First Aid CPR Law Enforcement and Emergency Medical Services Officer Roles and Responsibilities Introduction The first officer at the scene of an emergency situation assumes the role of First Responder. Primary responsibilities As EMS First Responders, officers should assume the primary responsibility for:  evaluating the emergency situation,  ensuring officer safety as well as the safety of ill or injured individuals and the public,  taking necessary enforcement actions related to the incident, and  initiating actions regarding the well-being and care of ill or injured persons. Scene evaluation At the scene officers should evaluate the nature of the incident and communicate critical information to dispatch and other involved staff as soon as possible. The following list identifies a number of factors that may be considered when evaluating the scene: Location Type of emergency Nature of ill/injured person(s) Need for additional resources Officer Roles and Responsibilities, continued Urgent enforcement actions required Safety Officers are responsible for taking action to protect their own safety as well as the safety of other EMS personnel, the ill or injured person, the public, and to control the scene. When determining appropriate safety precautions to take, officers should consider possible dangers from: Assessment and care of victim By nature of their training, officers should be capable of assessing the medical condition of any ill or injured person at the scene of an emergency. Based on this initial assessment, officers may be required to provide basic care for the victim. Such care may include providing basic emergency medical services until relieved of the responsibility by other personnel with equal or higher levels of training. 1 Enforcement actions If the care and well being of the victim has been turned over to other EMS personnel, officers may be required to continue additional enforcement actions including: Officer Welfare and Safety Introduction - Officers and all others within the EMS system must take appropriate precautions at all times when in direct contact with injured victims blood or body fluids. Pathogens - Infection and disease are caused by pathogens that are spread through the air or by contact with another person’s blood or body fluids. Bacteria - are microscopic organisms that can live in water, soil, or organic material, or within the bodies of plants, animals, and humans. The human body contains a number of both beneficial and harmful bacteria. Only when a bacteria is harmful would it be considered a pathogen. Virus - is a submicroscopic agent that is capable of infecting living cells. Once inside the cells of plants, animals, or humans, viruses can reproduce and cause various types of illness or disease. Transfer of pathogens - There are two primary methods by which pathogens can be transferred from one human being to another. Airborne pathogens - are spread by tiny droplets sprayed during breathing, coughing, or sneezing. Airborne pathogens can be absorbed through the eyes or when contaminated particles are inhaled. Blood borne pathogens - may be spread when the blood or other body fluids (e.g., semen, phlegm, mucus, etc.) of one person comes into contact with an open wound or sore of another. Exposure - Because of the nature of their occupation, officers are at a high risk of being exposed to both airborne and blood borne pathogens. NOTE: Exposure does not necessarily mean an individual will contract the illness. Personal protective equipment – Gloves, Face Masks, Body fluid protective suit, etc. By using personal protective equipment (PPE), EMS personnel can break the chain of transmission 2 and prevent possible exposure and infection. Equipment to be effective must be used and cared for properly. PPE disposal - Gloves, along with other equipment intended for single use, must be disposed of in an approved manner according to manufacturer recommendations after use or contamination. Disposal may include but not be limited to use of: NOTE: Officers are responsible for being aware of and complying with their agency’s policies and guidelines regarding the disposal of hazardous PPE and materials. Universal precautions - Along with using personal protective equipment, there are a number of universal precautions that officers as First Responders in the EMS system should take. NOTE: A solution of one part bleach and ten parts water can be used when disinfecting equipment. Personal preventive measures - Officers should also be aware of personal preventive measures they may take to remain healthy and support their own immune systems. Staying in good physical condition can help breach the chain of transmission of pathogens to which they may be exposed. Documentation of exposure - If a peace officer is exposed to an infectious pathogen (or even suspects exposure), no matter how slight, that officer should report the exposure verbally and in writing as soon as possible. NOTE: Officers should be aware of and comply with their agency policies or guidelines regarding reporting exposure and specific actions to be taken. Legal Protections Regarding Emergency Medical Services Introduction - Under certain specified conditions, peace officers are afforded qualified immunity from liability when rendering emergency medical services at the scene of an emergency. Responsibility to act As trained professionals, officers have a responsibility to: An officer is not required to render care when reasonable danger exists (e.g., while under fire, exposure to hazardous materials, etc.). Immunity from liability 3 The California Legislature has declared that emergency rescue personnel qualify for immunity from liability from civil damages for any injury caused by an action taken when providing emergency medical services under certain specified conditions. (Health and Safety Code Section 1799.102) To be protected from liability for civil damages, emergency rescue personnel must: Emergency rescue personnel means any person who is a peace officer, employee or member of a fire department, fire protection, or firefighting agency of the federal, state, city, or county government. Emergency medical services include, but are not limited to, first aid and medical services, rescue procedures and transportation, or other related activities necessary to ensure the health or safety of a person in imminent peril. Negligence - If peace officers attempt to provide emergency medical services beyond the scope of their training, or if they act in a grossly negligent manner, they can be held liable for any injuries they may cause. Failure to provide care, even though the officer has had the appropriate level of training to do so, may also lead to the officer being liable for any injuries caused because of lack of care (e.g., not providing CPR to a victim who is HIV positive). NOTE: Peace officers are responsible for complying with their agency policies regarding providing emergency medical services. Expressed consent - Officers should clearly identify themselves and ask for consent to administer emergency medical services. Consent (i.e., permission) must be obtained from the ill or injured person before providing emergency care. In order to give lawful consent, the ill or injured person must be: Refusal of care - A conscious and competent adult has the right to refuse any emergency medical services offered by emergency rescue personnel. The refusal must be honored as long as the person is mentally competent. Depending on specific agency policy or guidelines, an individual who refuses emergency medical services may be required to sign a release form relinquishing EMS personnel of responsibility for that individual. Implied consent - A legal position that assumes that an unconscious or confused victim would consent to receiving emergency medical services if that person were able to do so. Emergency rescue personnel have a responsibility to administer emergency medical services under implied consent whenever a victim is: NOTE: Whenever implied consent is assumed or if medical services are provided based on the seriousness of the victim’s condition, emergency rescue personnel should carefully document the conditions or the basis for their decision to treat the victim. 4 Life threatening conditions - If it is determined that an illness or injury is such that if left untreated the victim’s condition will degenerate to a life-threatening condition, the emergency rescue personnel may provide medical services regardless of the victim’s conscious condition. NOTE: Individuals who are terminally ill may have given specific do not resuscitate (DNR) instructions. Officers are responsible for being aware of and complying with their own agency’s policies and guidelines regarding following such instructions in an emergency situation. Duty to continue - Once an officer initiates medical services, that officer must remain with the victim until:  T he officer is relieved by an individual with equal or greater training and skill  The scene becomes unsafe for the officer to remain. Victim Assessment: Introduction - Once the emergency scene has been evaluated and necessary safety precautions taken, the next step for an EMS First Responder is to assess the victim’s condition. The purpose of this two-part assessment process is to identify and immediately treat life-threatening conditions and to set priorities for further treatment.  Two part process There are two parts to the victim assessment process: the primary survey and the secondary survey. Primary Survey 5  Rapid (30-45 seconds), systematic process to detect life threatening conditions  May also be referred to as the initial survey Secondary Survey  Systematic examination to determine whether serious conditions exist.  May also be referred to as the focused survey Respiration rate - The act of breathing is called respiration. Responsiveness - Before taking any action, the victim’s level of responsiveness (mental status) should be determined. To determine responsiveness, the officer should speak with the victim directly, asking, “Are you okay?” If the victim does not respond, the officer should tap the victim or shout in order to elicit a response from the victim. Depending on the level of responsiveness, a victim may be determined to be:  alert, awake and oriented (i.e., can talk and answer questions),  responsive to verbal stimuli (e.g., talking or shouting), or  responsive to painful stimuli (e.g., tapping or pinching, rubbing). IF the victim is... THEN the officer should... not responsive  activate the EMS system, and  check the victim’s CABs. Victim Assessment: Primary Survey, Continued responsive  control any major bleeding,  treat for shock, and  activate the EMS system if necessary. CABs When a victim is alert and able to speak, it can be assumed that the victim has a clear airway and is able to breath. If the victim is unable to speak or not responsive, then appropriate steps should be taken to check the victim’s CABs. Circulation The presence of a carotid pulse, taken at a carotid artery, is the most reliable indication that the victim’s heart is functioning.  Place an index and middle finger on the front of the victim’s throat at the largest cartilage of the larynx (“Adam’s apple”).  Slide fingers off the victim’s throat to the side of the neck toward the officer.  Position fingers between the trachea (“windpipe”) and the large muscles on the side of the victim’s neck for five to ten seconds. NOTE: For infants under one year, circulation should be assessed on the brachial artery (inside upper arm between biceps and triceps). 6 IF the victim has... THEN the officer should... no pulse  begin cardiopulmonary resuscitation (CPR). a pulse but is not breathing  give the victim two full breaths  each approximately 1 seconds long. NOTE: If the first breaths do not go in, reposition the airway and try to ventilate again. If the breaths do not go in the second time, use the appropriate technique to force the obstruction from the airway. a pulse, is breathing, but unconscious  check for indications of life-threatening conditions (e.g., major bleeding, shock, etc.).  place the victim in the recovery position (on the side with the head supported by the lower forearm), if appropriate, to aid breathing and allow fluids or vomitus to drain from the mouth. a pulse, is breathing, and conscious  check for indications of life-threatening conditions (e.g., major bleeding, shock, etc.). Airway - The airway is the passageway by which air enters and leaves the lungs. An airway obstruction may be caused by the position of the victim’s tongue, head, or jaw, or some type of obstruction in the victim’s throat. The following table identifies basic actions associated with opening a victim’s airway:  Use a head-tilt/chin-lift maneuver to lift the tongue away from the air passage. Breathing - After ensuring that the victim’s airway is clear and open, the responding officer should determine if the victim is breathing.  Take a position with the officer’s ear near the victim’s mouth and eyes looking toward the victim’s chest.  Check for breathing for five seconds by: Victim Assessment: Primary Survey, Continued Life-threatening conditions - Once it is determined that the victim is breathing and has a pulse, the officer must control any major bleeding and treat the victim for shock. Such conditions must be treated first before any further assessment of the victim takes place. 7 NOTE: Techniques for administering emergency first aid measures for controlling bleeding, treatment for shock, and other conditions are noted in later sections. Multiple Victim Assessment Introduction In some emergency situations, there will be more than one victim. In such situations, it is the officer’s responsibility as EMS First Responder’s to classify the victims for treatment. By doing so, treatment will be rendered first to those victims needing immediate attention for life-threatening conditions. Classification categories Officers should move from one victim to another, making a quick (less than one minute) assessment of each victim’s condition and classifying each victim into a category. The following table identifies the classification categories: Category Action NONSALVAGEABLE - No further action (obviously dead or not breathing) IMMEDIATE - Receives treatment first, once all victims are classified DELAYED - Receives treatment once all victims classified as IMMEDIATE have been treated MINOR - Directed to a safe area away from other victims and possible scene safety hazards Assessment criteria Classification categories should be based on assessment of that victim’s breathing, circulation, and mental status. The following table describes the order of the assessment process and criteria for classifying each victim: Actions IF... THEN... Breathing  Clear airway if necessary.  Measure respiration rate. no respiration - classify victim as NONSALVAGEABLE . over 30 cycles/min.  classify victim as IMMEDIATE. below 30 cycles/min.  continue assessment by checking the victim’s circulation. Circulation - Take radial pulse or capillary refill on extremities. 8 pulse absent  classify victim as NONSALVAGEABLE pulse present  continue assessment by checking the victim’s mental status. Multiple Victim Assessment, continued Mental Status  Give simple commands such as “Open your eyes,” or “Close your eyes.” unable to follow commands  classify victim as IMMEDIATE. Follows commands  classify victim as DELAYED or MINOR. Begin treatment - After completing the assessment and classification of all victims, treatment of victims classified as IMMEDIATE can begin. Moving a Victim Introduction As an EMS First Responder, one of the most difficult decisions an officer may need to make at an emergency scene is whether or not to move a victim. DO NOT MOVE - More harm can be done to a victim through moving that person than by the original injury. This is especially true if a spinal cord injury is suspected. DO NOT MOVE - any injured victim unless it is absolutely necessary. An unconscious, injured victim should be treated as though the victim has a spinal injury and therefore should not be moved unless it is absolutely necessary. Conditions for moving a victim - A victim should be moved only when the victim is in a life- threatening situation. Imminent danger Unable to assess  When it is not possible to do a primary survey (CABs) of the victim’s condition  When the victim’s condition or an officer’s ability to provide basic life-saving procedures is not possible due to the victim’s position  Slumped over a steering wheel  When CPR is required General guidelines If an injured person must be moved, officers should consider the following guidelines. Plan Ahead 9  Identify a safe location before attempting to move the victim.  Move only as far as is absolutely necessary. Reassure Victim  Tell the victim(s) what is going on and why the victim is going to be moved.  Keep the victim as calm as possible. Victim Stability  Keep victim in a straight line during the movement.  Keep victim lying down.  Move the victim rapidly but also as carefully and gently as possible.  Be careful not to bump the victim’s head during movement. NOTE: If an infant is fastened in an infant seat, do not remove the infant. Move infant and the seat together. Moving a Victim, continued Shoulder drag A number of different techniques may be used to move an injured victim. One maneuver that may be used is the shoulder drag technique. It can be done if the victim is in either a supine (face up) or prone (face down) position. To avoid straining their backs when dragging a victim, officers should:  bend their knees  keep their backs straight  let their leg muscles do most of the work. The basic steps for the shoulder drag technique are noted below: Step / Action 1. Use hands and grasp the victim under the armpits. 2. Stabilize the victim’s head and neck to reduce the risk of injury. 3. Carefully lift the victim keeping the head and shoulders as close to the ground as possible. 4. Drag the victim so that the head, torso, and legs remain in a straight line. 5. DO NOT pull sideways. 6. Gently place the victim in the new location. 7. Assess the victim’s condition. 10 Basic Life Support Officers may be required to provide basic life support for a victim, fellow officer, or themselves until additional medical services become available. Assess breathing Once the victim’s airway has been opened, officers must assess whether or not the person is breathing. This is done by checking for breathing:  looking for the rise and fall of the chest  listening for the sound of breathing, and  feeling for breath from the victim’s nose or mouth. Ventilation If it is determined that the victim is not breathing, officers should:  give two full slow breaths  each approximately 1 second long. If the breaths do not go in, the victim’s airway should be repositioned and ventilation should be repeated. If the breaths still do not go in, officers should look for an airway obstruction. Airway obstructions An airway obstruction can be either partial or complete. They are caused by a number of different materials blocking the person’s air passages. Examples include, but are not limited to the following.  Victim’s tongue  Vomitus or blood  Blood  Broken teeth or dentures  Foreign objects such as toys, ice, food Partial airway obstruction - If the victim indicates an airway problem (i.e., choking) but is able to speak or cough, the victim is experiencing a partial airway obstruction. With a partial 11 airway obstruction, it may be assumed that there is adequate air exchange to prevent respiratory failure. A victim who is conscious with a partial airway obstruction should be encouraged to cough forcefully to dislodge and expel the object. Do not interfere with the victim’s attempts to cough. (e.g., pound on the victim’s back). This could lodge the obstruction even further, causing a Complete airway obstruction - If the obstruction cannot be removed by coughing and the victim has labored breathing, is making unusual breathing sounds, or is turning blue/grey, the victim should be treated as if there is a complete airway obstruction. NOTE: Grabbing the throat with one or both hands indicating the victim is unable to breath is considered the universal choking sign. Basic Life Support, continued Complete obstruction - The victim may be experiencing a complete airway obstruction if:  unconscious and unable to be ventilated after the airway has been opened, or  conscious but unable to speak, cough, or breathe. Under such conditions, additional measures may be required to free the victim’s airway from a complete obstruction. The two primary maneuvers used are the abdominal thrust and the chest thrust. Removing obstruction - If any object causing the obstruction can be seen it might be removed by using a finger sweep. To conduct a finger sweep:  open the victim’s mouth by grasping both the tongue and lower jaw between the thumb and fingers,  insert the index finger of the other hand down along the cheek and then gently into the throat in a “hooking” motion, and  if the object can be felt, grasp it and remove it. NOTE: The finger sweep maneuver should be done with care so that the object is not forced further into the victim’s throat. NOTE: Do not use a blind finger sweep. Objects should be removed from their mouths only if the objects can be seen clearly. Abdominal thrust - The abdominal thrust (also referred to as the Heimlich maneuver) is one method used to force obstructions from a victim’s airway that cannot be removed with a finger sweep. Abdominal thrusts force air out of the lungs, expelling the obstruction, and clearing the victim’s airway. NOTE: For the purposes of this course, an adult is eight years and older; a child is one to eight years. 12 Conscious choking adult or child 1. Ask the victim, “Are you choking?”, “Can I help you?” 2. Determine that the victim is choking (i.e., unable to speak, cough, or breathe). 3. Inform the victim before taking action. 4. Take a position behind the victim. 5. Wrap arms around the victim’s waist and locate the victim’s navel. 6. Make a fist with one hand. 7. Place the thumb side of the fist against the midline of the victim’s abdomen, above the navel. 8. Grab fist with other hand. 9. Apply pressure inward and upward toward the victim’s head in a smooth, quick movement. 10. Repeat thrusts until object is expelled or victim loses consciousness. Basic Life Support, continued Chest thrusts - The chest thrust is another maneuver that can be used to force obstructions from a victim’s airway. Chest thrusts are used when the victim:  has gone unconscious  is in late stages of pregnancy  has abdominal injuries  is too obese for abdominal thrusts to be effective. Unconscious adult or child 1. Activate the EMS system. 2. Place victim in a supine position. ( On their back) 3. Open the victim’s airway. 4. Remove any visible obstruction. (Do not use a blind finger sweep.)  Attempt to ventilate victim’s lungs.  If airway remains obstructed, reposition the victim’s head and attempt to ventilate again.  If airway remains obstructed, Begin CPR.  Two hands in the center of the chest at the imaginary nipple line for an adult/child.  For Adult - Place the heel of the hand closest to the victim’s feet on top of the heel of the other hand at the compression point.  For Child - Place one or two hands (depending on officer/victim size and strength factors) at the compression point.  Straighten and lock elbows.  Position shoulders directly above hands.  Using body weight, push straight down with enough force to compress the sternum at least 2 inches for an adult.  If victim is a child, compress the sternum 1/3-1/2 the depth of the chest.  Fully release compression pressure in the same amount of time it took to apply it.  Deliver 30 compressions at a rate of at least 100 per minute. 13 Infants - A combination of back blows and chest compressions may be used to clear a foreign body from an infant’s airway. The following table identifies techniques for chest thrusts on both conscious and unconscious infants: NOTE: For the purposes of this course, an infant is newborn - one year. Conscious choking infant Step / Action 1. Confirm that the infant’s airway is obstructed (serious breathing difficulty, ineffective cough, absence of a strong cry). 2. Do not attempt to ventilate or conduct a finger sweep. 3. Support infant’s body on forearm, face down. (The officer’s arm may be resting on one leg for additional support.) Basic Life Support, continued 4. Place infant’s face in the palm of the hand with the infant’s nose between the forefinger and middle finger. 5. Position the infant’s head lower than the body. 6. Using the heel of one hand, deliver up to five blows to the infant’s back between the shoulder blades. 7. If the airway remains obstructed, turn infant over so that the back of the infant’s head is supported by the hand. 8. Keep the infant’s head lower than the body. 9. Place fingers of one hand on the center of the infant’s chest, one finger width below the nipples but above the xiphoid process. 10. Deliver five chest thrusts to compress the infant’s chest 1/3-1/2 the depth of the chest. 11. If the airway remains obstructed, alternate between five back blows and five chest thrusts until the obstruction is clear or the infant loses consciousness. Unconscious infant 1. Activate the EMS system. 2. NOTE: Officers should have a second person (if available) activate the EMS system, while the officers begin the maneuver immediately. 3. Position infant on its back. 4. Carefully, open the infant’s airway. 5. Look in the infant’s mouth. 6. If obstruction is visible, carefully remove it. 7. If airway remains obstructed, reposition the infant’s airway and attempt to ventilate. 8. If air does not enter the infant’s airway, reposition the infant’s airway and attempt to ventilate a second time. 9. If airway remains obstructed, Begin CPR. 14 10. Using 1-2 fingers, find the compression point one finger width below the imaginary nipple line. 11. Compress the sternum 1/3-1/2 the depth of the chest. 12. Fully release compression pressure in the same amount of time it took to apply it. 13. Deliver 30 compressions at a rate of at least 100 per minute. Rescue Breathing Introduction If it is determined that a victim’s airway is open and no obstructions are present, yet the victim is still not breathing, the officer may attempt rescue breathing. Rescue breathing - is the process of using one’s own breaths to artificially breathe for a victim. The rescue breathing process continues until the victim is able to breathe without assistance or other breathing support is provided by EMS personnel. Scene safety - Ensure scene safety by taking universal precautions. Responsiveness  Establish that the victim is unresponsive.  Activate the EMS system. (If a second person is available, have that individual activate the EMS system.) Checking CABs Prior to beginning rescue breathing, a primary survey of the victim should take place. The primary survey should include determining the victim’s responsiveness as well as checking the victim’s CABs.  Circulation to identify if the victim has a pulse.  Airway to ensure the victim’s airway is open, Breathing to determine if the victim is breathing (If it is determined that the victim is not responsive, has a pulse, has an open airway, but is not breathing, then rescue breathing may be required.) Rescue breathing technique  Open the victim’s airway using the head-tilt/chin-lift or jaw-thrust maneuver (whichever is most appropriate for the situation.). Portable pocket mask 15 o nose.  Take a breath and slowly exhale directly into the victim’s mouth or through the one- way valve of the mask.  Use only enough air to create a gentle rise in the victim’s chest.  Break contact with the victim’s mouth or the mouth piece of the mask. Rescue Breathing, continued  Watch the victim’s chest as the air is released from the victim’s lungs.  If breaths do not enter the victim’s lungs: reposition the victim’s head to open the airway, attempt to breathe into the victim’s lungs again.  Repeat the breathing cycle until the: NOTE: If the victim begins to breathe without assistance, continue to assess the victim’s condition and provide care for shock. Other conditions If the victim’s mouth is injured and cannot be used for rescue breathing, the officer should use a mask-to-nose position. If the victim has a laryngectomy, a surgical procedure that implants an artificial airway (stoma) in the neck, the officer should use a mask-to-stoma position. For both positions, the same methods should be used as with mouth-to mouth/face mask techniques for rescue breathing. Rescue breathing rates and duration Rescue breathing duration and rate will vary depending on the victim’s age. Adult (8 years and older) = 1 breath every 5-6 seconds. Child (1 - 8 years) = 1 breath every 3-5 seconds. Infant (newborn - 1 year) = 1 breath every 3-5 seconds. NOTE: Officers should use their best judgment when estimating the age of a child or infant. Reassessing: Reassessment should be completed every two minutes. CAB’s should be checked every two minutes. If the victim is:  has no pulse, begin cardiopulmonary resuscitation (CPR).  has a pulse but not breathing, continue rescue breathing. 16 Rescue Breathing, continued Recovery position If the victim resumes adequate breathing and there are no indications of major bleeding or spinal injury, then the victim can be placed in the recovery position. This position allows for drainage from the mouth and prevents the victim’s tongue from blocking the airway. To place a victim in the recovery position:  roll the victim onto either side toward the officer,  keep the victim’s body in one unit with the spine as straight as possible,  move the victim’s lower arm up and bend at the elbow,  rest the victim’s head on the lower forearm,  move the victim’s top leg toward the victim’s chest, and  continue monitoring the victim’s breathing. Vomiting - If a victim vomits, the vomitus may enter the lungs and cause further life threatening complications. If vomiting should occur:  turn the victim’s entire body (not just the head) to the side as one unit to keep the spine straight,  wipe the vomitus from the victim’s mouth,  return the victim to the supine position,  re-open the airway, and continue rescue breathing. 17 Cardiopulmonary Resuscitation (CPR) Introduction If a victim is unresponsive, not breathing, and has no carotid pulse to indicate circulation, then the victim is in a state of cardiac arrest. Without immediate care, the victim will die. CPR Cardiopulmonary resuscitation (CPR) is a method of artificially restoring and maintaining a victim’s breathing and circulation. CPR is a key element of basic life support. In order to survive, oxygenated blood must circulate through the body and reach the victim’s brain. In order to ensure that this process takes place, an officer must:  physically force the victim’s blood to circulate (external chest compressions).  maintain an open airway,  breathe for the victim (rescue breathing) Clinical and biological death A victim is clinically dead the moment breathing and circulation stop. Clinical death may be reversible if basic life support techniques such as CPR are begun immediately. When a victim’s breathing and circulation stop and brain cells die due to lack of oxygen, irreversible changes begin to take place, and vital organs begin to deteriorate. At this point, a victim is biologically dead. Biological death usually takes place within four to six minutes after breathing and circulation stop. NOTE: If any doubt exists as to whether or not the victim is alive, CPR should be started. NOTE: The point at which a victim is considered to be biologically dead may be defined by specific agency guidelines and policy. “Do not resuscitate” orders A valid “do not resuscitate” (DNR) or “no-CPR” directive would also be a reason for not beginning CPR on a victim. If there is any doubt that the order may not be valid or if a family member requests that an order be ignored, CPR should be started. Specific agency policy Different agencies may have specific policies and guidelines regarding performing CPR on unconscious adults, children, and infants, or DNR orders. Officers are responsible for knowing and complying with their agency policies. Checking CABs Prior to beginning CPR, a primary survey of the victim should take place. The primary survey should include determining the victim’s responsiveness as well as checking the victim’s CABs.  C irculation to identify if the victim has a pulse  A irway to ensure the victim’s airway is open  B reathing to determine if the victim is breathing If the victim does not has a pulse (circulation), begin CPR immediately! 18 Cardiopulmonary Resuscitation (CPR), Continued Adult/child CPR: Once a peace officer has confirmed the victim’s mental state, conducted a primary survey, and has determined that there is no breathing or circulation, CPR should begin immediately. NOTE: For the purposes of CPR, a child is defined as one to eight years. Actions 1. Responsiveness  Establish that the victim is unresponsive.  Activate the EMS system. (If second person is available, have that individual activate the EMS system.) 2. Position  Place victim in a supine position on a firm surface. 3. Pulse  Check for a carotid pulse over a five to ten second time period.  If victim has: 4. Compression Point NOTE: External compressions are not effective unless performed in the correct position. Compressions to the wrong part of the chest may lead to further injury of the victim. 5. External Compressions  Straighten and lock elbows.  Position shoulders directly above hands.  Using body weight, push straight down with enough force to compress the sternum at least 2 inches.  If victim is a child, compress the sternum 1/3-1/2 the depth of the chest.  Fully release compression pressure in the same amount of time it took to apply it.  Deliver 30 compressions at a rate of at least 100 per minute.  (Count out loud “1, 2, 3, ....”) Adult/child CPR: one person (continued) 6. Airway  Open the victim’s airway using head-tilt or jaw-thrust maneuver.  Check for breathing. Look, listen, and feel for breathing once the airway is open. NOTE: If already breathing or breathing resumes effectively once the airway is opened, place victim in a recovery position, when appropriate. 7. Initial Ventilation 19  If available, use a pocket face mask for ventilation during CPR.  Give two breaths with each lasting 1 second.  Blow into the victim’s mouth until resistance is noted. (Feel for resistance orally and watch for the victim’s chest to rise.).  Allow victim to exhale between breaths. 8. Ventilation/Compression Cycle  After 30 compressions, reposition victim’s airway.  Give two slow, full breaths.  Continue cycle of 30 compressions to 2 breaths for 5 cycles (approximately 2 minutes). 9. Assessment  Assessment/reassessment should be done every 5 cycles or 2 minutes.  Recheck carotid pulse and look, listen, and feel for breathing over a period of five seconds.  If victim has: Infant CPR The technique for performing CPR on an infant (newborn to one year of age) is similar to that for adults, but with adjustments that take into accounts the infant’s size. Actions 1. Responsiveness  Establish that the victim is unresponsive.  If second person is available, have that individual activate the EMS system. (If officer is alone, begin CPR immediately.) 2. Position  Place victim in a supine position on a firm surface. Infant CPR: one person (continued) 3. Airway  Gently open the victim’s airway using head-tilt maneuver. (Do not over extend the infant’s neck.)  Check for breathing. Look, listen, and feel for breathing once the airway is open. 4. Initial Ventilation  Give two, gentle puffs of air with each lasting 1 second until the victim’s chest visibly rises.  Allow victim to exhale between breaths. 20 5. Pulse Check for a brachial pulse over a five second time period.  If victim has: 6. External Compressions  Locate compression point on the victim’s breastbone, one finger width below the imaginary line between the nipples.  Using two fingers only, depress the victim’s breast with enough force to compress the sternum 1/3-1/2 the depth of the chest.  Deliver 30 compressions at a rate of at least 100 compressions per minute.  Follow with two breaths(puffs) (30 compressions to two breaths). 7. Assessment  Check brachial pulse after two minutes.  If victim has: 8. Stopping of CPR CPR must be continued until:  the victim’s breathing and circulation resumes,  the officer is relieved by an equally or higher medically trained person,  the officer is too exhausted to continue,  environmental hazards endanger the rescuer (e.g., gun shots),  continued CPR efforts would endanger the lives of others, or it is determined the victim is biologically dead. Bleeding Control Introduction Large or deep wounds or injuries can lead to uncontrolled bleeding, which in turn can lead to shock and eventually death. Circulatory system The three components to the human circulatory system are the:  heart,  blood vessels, and  blood. If any one component does not function properly, oxygen and nutrients will not reach the body’s major organs in sufficient enough supply to support life. Bleeding control techniques There are four techniques that may be used to control or limit bleeding at the scene of a medical emergency. 1. Direct pressure  Direct pressure applied to the bleeding site until bleeding is controlled  Use of a bandage to hold a pressure dressing in place  Most common and effective technique  Should be used first before other bleeding control options  May be done by firmly applying direct pressure over the bleeding site using clean dressing NOTE: If clean dressing is not available, a gloved hand or other clean material may be used. 21 2. Elevation  Use of gravity to help reduce blood pressure to the site and slow the bleeding  Elevate bleeding site above the level of the heart  Used in combination with direct pressure NOTE: Should not be used if a fracture to that limb or a spinal cord injury is suspected. 3. Pressure Points  Applying direct pressure to a specific location where an artery is close to the body surface and near a bone  Used when bleeding is not controlled through pressure, elevation, or pressure bandage Brachial artery  Used to control bleeding from upper limbs  Pressure is applied by placing the pads of fingers into the groove between the victim’s biceps muscle and bone  Pressure should be maintained until bleeding is controlled Femoral artery  Used to control bleeding from lower limbs  Pressure is applied by placing the pads of fingers into the crease between the victim’s abdomen and leg  Pressure should be maintained until bleeding is controlled Bleeding Control, Continued 4. Tourniquet  Use of a device to close off all blood flow to and from a limb  Should only be used for life threatening conditions as a last resort when all other methods have failed  Can be made of any material wide enough (at least 2 inches) so as to not cut into the victim’s skin (e.g., flat belt, stocking, necktie, etc.)  Apply close to the wound, between the wound and the victim’s heart (but not over a joint)  Wrap material around limb and draw tightly to the point where the bleeding is stopped and no further bleeding occurs. Note the time the tourniquet is placed; report to EMTs  If victim is covered, leave the area where the tourniquet is located exposed for EMTs to see  Tourniquet should not be loosened or removed once in place NOTE: A dressing is any material applied to a wound to control bleeding and prevent contamination. A bandage is any material used to hold a dressing in place. Bleeding Control, Continued Open wounds 22 An open wound is any injury where the skin has been broken, exposing the tissue underneath. Abrasions, incisions, lacerations, punctures, avulsions, and amputations are all examples of open wounds requiring attention to control bleeding. Abrasion - A scraping away of only outer portion of the skin  Rug burns  Road burns  Skinned elbows/ knees Incision - Smooth, straight cut caused by sharp objects  Paper cuts  Razors  Edge weapons Laceration - Jagged-edged wound caused by objects tearing or ripping the skin  Broken glass  Jagged metal  Saws  Severe blow or impact with blunt object Puncture - Deep wound through the skin and other tissue  Arrows  Knives  Nails  Bullets  Impaled objects Bleeding Control, Continued NOTE: Penetrating punctures have only an entrance wound and can be shallow or deep. Perforating punctures have an entrance wound and an exit wound. Avulsion - A part or structure of the body that has been forcibly torn or cut away  Tip of nose that is cut off  External portion of ear torn away  Eye pulled from its socket Amputation - Surgical or traumatic removal of a body extremity  Jagged skin and bone edges may be exposed  May involve massive bleeding  Accidents involving chain saws, industrial equipment, etc. Care for open wounds General Guidelines Assessment  Expose the injury site before applying bleeding control (e.g., remove, loosen, or cut away clothing covering the wound).  Assess for possible fractures associated with open wound. 23  To prevent any further contamination of the wound, do not attempt to clean the wound before applying dressing to control bleeding. Immediate care  Control Bleeding  Cover the entire wound site with dressing.  Apply pressure to stop bleeding.  Bandages should be applied snugly but not so tight as to impair circulation to portions of the body distal (farther away from the torso) to the wound site.  Leave fingers and toes exposed. Impaled Objects  Do not attempt to remove the object. (Any movement of the object could cause further damage or increased bleeding.)  Control bleeding by applying pressure on both sides of the object.  Do not put pressure on the object itself. Avulsions/Amputations  Place partially separated skin or tissue back in proper position before applying dressing and bandage.  Attempt to locate any avulsed part or amputated extremity.  Keep separated part/extremity dry, cool, and protected.  Do not immerse, pack in ice, or freeze separated part/extremity.  Transport separated part/extremity with victim for possible surgical replacement Bleeding Control, Continued Circulation  Monitor pulse below the injury site.  Check capillary circulation by pinching fingertips or toes. (Color should return immediately to pinched area.)  If circulation is impaired, loosen bandage (do not remove) until circulation improves. Continued care  If necessary, immobilize the injury site (e.g, open fracture).  Keep the victim lying still to prevent an increase in circulation.  Maintain pressure on wound.  Monitor the victim’s CABs.  Reassure the victim. (Fear and anxiety can increase a victim’s heart rate and circulation.)  Treat for shock. 24 Shock Introduction Shock is a life-threatening condition. If not immediately cared for, the victim can die. Perfusion is the continued flow of blood through the capillaries supplying the body’s tissues and organs with oxygen and removing waste products. Inadequate perfusion leads to shock. Indicators of Shock  Altered mental status  Oxygen deficiency to the brain  Pale, cool, clammy skin  Profuse sweating  Thirst, nausea, vomiting  Blue/grey lips, nail beds, tongue, ears (i.e., cyanosis)  Dull eyes, dilated pupils  Rapid pulse rate C Weak or “thready” pulse  Shallow, labored breathing NOTE: There may be no relationship between severity of an injury and the onset of shock. Victims may appear to have no major injury but still show signs of restlessness or anxiety, which are early stages of shock. For this reason, all victims of traumatic or medical emergencies should be provided care for shock from the time of initial contact. 25 Fainting is a form of shock characterized by sudden unconsciousness. It is caused by dilation of blood vessels resulting in reduced flow of oxygenated blood to the brain. Treating shock All victims should be treated for shock even if no indications of shock are evident. When providing care to treat shock, officers acting as EMS First Responders should:  control all external bleeding and treat other injuries,  gently place the victim in appropriate position,  be alert for vomiting,  maintain the victim’s body temperature but avoid overheating,  place the victim in a position to help maintain blood flow,  reassure the victim, and  continue to monitor the victim’s CABs and be prepared to take action if necessary (e.g., rescue breathing, CPR). NOTE: Overheating the victim may worsen shock. A blanket beneath a victim may be more effective in reducing heat loss than one placed on top of the victim. Shock, continued Thirst - Even though the victim may be thirsty, do not give anything to drink. Shock can cause the gastrointestinal system to shut down. Fluids given orally may lead to vomiting. Positioning victim During treatment for shock, the position in which the victim is placed is dependent upon the nature of the injury or illness. If lower limb or spinal fractures are not suspected:  place the victim in a supine position and  elevate legs approximately 6-12 inches. 26 Traumatic Injuries Head Injuries Introduction Any person who has suffered a traumatic injury may also be subject to a possible brain or spinal cord injury. For this reason, officers, acting as EMS First Responders, should treat all traumatic injury victims as if they have a head injury. Indications of head injury Head injuries can involve injuries to the skull, scalp, brain, blood vessels and fluid around the brain, and/or neck. They may vary from those involving minor bleeding to those leading to life-threatening conditions and spinal cord injury. Indications of Possible Head Injury  Striking a vehicle’s windshield or dashboard  Blow to the head  Falls Mental Status  Agitated or confused  Combative or appears intoxicated  Decreased level of consciousness (e.g., appears “groggy”)  Loss of short term memory  Loss of consciousness (even for a short period of time) Vital Signs  Abnormal breathing patterns 27  Decreased pulse  General deterioration of vital signs Visible Injury  Deformity of head/skull (e.g., protrusions, depressions, swelling, bruising, etc.)  Visible bone fragments Indications of Possible Head Injury Appearance  Clear or bloody fluid from ears and/or nose  Unequal pupils  Bruises behind ears (i.e., “battle scars”)  Discoloration around eyes (i.e., “raccoon eyes”)  Paralysis  Blurred vision  Projectile vomiting NOTE: The extent of a head injury may not always be obvious. Whenever a victim has suffered a traumatic head or neck injury, brain and spinal cord damage should always be assumed. Head Injuries, Continued First Aid Measures for Head Injuries Position  Do not move the victim’s head or neck.  Have the victim remain in the position in which found. Assessment  Determine level of consciousness.  Conduct a primary and secondary survey.  If necessary, use the jaw-thrust maneuver to open victim’s airway. Treatment  Activate the EMS system.  Control bleeding if necessary.  Be alert for the presence of cerebrospinal fluid in ears or nose. If present, bandage loosely so as not to restrict the flow.  Do not apply direct pressure to any head/skull deformity.  Be prepared for sudden and forceful projectile vomiting.  Treat for shock.  Do not elevate the victim’s legs.  Reassure the victim.  Continue to monitor CABs. Impaled objects (Head injuries) Unlike treatment for other situations involving impaled objects, any object (e.g., knives, arrows, screw drivers, etc.) that is impaled into a victim’s cheek or face and may cause an airway obstruction should be removed. If the impaled object is obstructing the victim’s airway: 28  carefully pull the object out from the direction it entered, and place dressing on both the inside and outside of the cheek to control bleeding.  If the object resists coming out, stop. Do not pull any farther. Place a protective device around it to stabilize the object (e.g., paper cup) and secure the device with a bandage. NOTE: If there is no airway obstruction, do not attempt to remove the object. Nosebleeds Victims with facial injuries may experience an accompanying nosebleed. If this occurs and no spinal injury is suspected, have the victim:  assume a seated position,  lean slightly forward,  pinch the nose midway at the point where bone and cartilage meet, and  maintain the position until bleeding stops. If the victim is unconscious:  slightly elevate the victim’s head, or  place the victim in the recovery position, if appropriate, and  maintain an open airway. NOTE: Do not pack the victim’s nostrils. This could cause blood to back up and create an obstructed airway. Chest and Abdominal Injuries Introduction Traumatic injuries to the chest or abdomen are potentially serious because of possible damage to the lungs and vital organs. Types of chest and abdominal injuries Traumatic injury to the chest and/or abdomen can lead to bleeding (external and internal) as well as damage to the lungs, heart, and other vital organs. The chest and/or abdomen may be injured in a number of ways. Blunt trauma  Blow to the chest and/or abdomen causing:  Penetrating object  Caused by bullets, knives, metal or glass, etc.  Can lead to:  Compression along with rapid chest and/or abdomen compression (e.g., striking a steering wheel)  Can lead to: Closed chest wound Although there may not appear to be any serious injury to the chest, blunt trauma or compression to the chest area can lead to a condition referred to as flail chest. Flail chest is the condition where the ribs and/or sternum are fractured in such a way that a segment of the chest wall does not move with the rest of chest wall during respiration. It is caused when two or more ribs next to each other are broken. Indicators First Aid Measures 29  Paradoxical breathing (when both sides of the chest do not move in a synchronized manner)  Painful and shallow breathing Open chest wound All open wounds to the chest should be considered life-threatening. For respiration to take place properly, the chest must function as a vacuum. With an open chest wound, air may enter the chest area causing a lung to collapse (e.g., sucking chest wound with a punctured lung). Under such conditions, the victim’s ability to breathe, and the victim’s heart function can be greatly impaired. To prevent air from entering the chest cavity, an occlusive dressing should be applied to the wound as quickly as possible. Occlusive dressing An occlusive dressing:  is a nonporous dressing (e.g., plastic bag), used to cover the wound, and  creates an air-tight seal. NOTE: As the victim inhales, the dressing is sucked tight to the skin, providing a seal over the wound. If the dressing is placed properly, respiration should partially stabilize. Applying an occlusive dressing  Place a gloved hand over the wound to “seal” the wound.  Without moving the hand covering the wound, use the free hand to place a piece of plastic over the hand covering the wound site. NOTE: Plastic should be at least two inches wider than the wound itself.  While using the free hand to apply gentle pressure and maintain the seal around the wound, gently remove the other hand from under the plastic.  Tape all but one corner of the plastic in place.  The untaped corner will allow air to escape from the chest cavity when the victim coughs.  Provide care to prevent shock.  Continue to monitor the victim’s CABs. NOTE: If the chest has both entrance and exit wounds, occlusive (airtight) dressings should be placed on both wounds. Closed abdominal wound A victim with a closed abdominal wound will have no external bleeding but may have internal bleeding that can be severe and potentially life-threatening. If a closed abdominal wound is suspected, peace officers should initiate the following first aid measures. Chest and Abdominal Injuries, Continued 30 Indicators First Aid Measures  Victim found lying in a fetal position (with legs pulled up to chest)  Rapid shallow breathing  Rapid pulse  Rigid or tender abdomen with or without swelling  Pain or tenderness to the touch during secondary survey  Activate EMS system.  If no spinal injury suspected, place victim in a comfortable position (e.g., supine with knees bent up).  Treat for shock.  Continue to monitor the victim’s CABs.  Be prepared for the victim to vomit. Open abdominal wounds An open abdominal wound can be caused by lacerations and punctures to the abdomen. Blood loss and the potential for infection should be of concern when dealing with an open wound to the abdomen. If an open abdominal wound is identified, peace officers should initiate the following first aid measures. First Aid Measures Assessment  Determine the victim’s state of consciousness.  Conduct primary and secondary surveys. Treatment Activate EMS system.  If no spinal injury is suspected, place the victim in a supine position with the knees up.  Place a sterile dressing over the wound.  Apply an occlusive dressing over the dressing to prevent the wound from drying out.  Secure all sides of the occlusive dressing.  Place a thick pad or cover over the occlusive dressing to maintain additional warmth to the abdominal cavity.  Treat for shock.  Continue to monitor the victim’s CABs.  If any organs or portion of an organ protrude from the abdominal wound, do not attempt to touch, move, or replace them. Cover the organ and the rest of the wound with a moist dressing and seal with an occlusive dressing. Bone, Joint, and Muscle Injuries 31 Introduction Musculoskeletal injuries may have a grotesque appearance. Officers should not be distracted by the injury’s appearance or begin first aid measures until an assessment is completed and treatment for other life-threatening measures are taken. Musculoskeletal system The musculoskeletal system is the system of bones, muscles, and other tissue that support and protect the body and permit movement. The components of the musculoskeletal system include bones, joints, skeletal muscles, cartilage, tendons, and ligaments. Description: Bone  Hard yet flexible tissue  Provides support for the body as well as protection of the vital organs Joint  Place where bones fit together  Proper function is critical in order for the body to move Skeletal Muscle  Soft fibrous tissue  Controls all conscious or deliberate movement of bones and joints Cartilage  Connective tissue that covers the outside of the ends of bones  Firm but less rigid than bone  Helps form certain flexible structures of the body (e.g., external ear, connections between the ribs and sternum, etc.)  Allows for smooth movement of bones at joints Tendon  Bands of connective tissue that bind muscles to bones Ligament  Connective tissue that attaches to the ends of bones and supports joints  Allows for a stable range of motion Musculoskeletal injuries Types of force that can cause injury to the musculoskeletal system: Direct - Direct blow to an area  Being struck by an automobile Indirect - Force from a direct blow to one area which causes damage to another  Landing on feet from a fall and injuring ankles, knees, etc. Twisting - Sudden rapid movement that stretches or tears  Football and other sport related injuries Bone, Joint, and Muscle Injuries, Continued 32 Types of injuries The four most common injuries are fractures, dislocations, sprains, and strains, are identified below: Fractures - Complete or partial break of a bone including:  open fractures where there is a break in the skin at the site of the fracture  closed fractures where there is no break in the skin at the site of the fracture  Limb deformity (differences in size or shape)  Swelling or discoloration to the area  Tenderness and localized pain  Breaking and/or grating sound  Possible loss of function Dislocations - When a bone is pushed or pulled out of alignment from a joint  Constant pain  Increased pain with movement  Joint deformity  Swelling  Loss of movement (i.e., “frozen joint”) Sprains - Severely stretched or torn ligaments  Associated with joint injuries  Pain  Swelling  Discoloration Strains - Over-stretching or tearing of muscle NOTE: Unless there is an obvious deformity or open wound with exposed bone, it is not possible to determine whether an injury is a fracture, dislocation, sprain, or strain without X- ray and other diagnostic procedures. When a musculoskeletal injury is suspected and the injury is severe (i.e., fracture), peace officers should use the following first aid measures. First Aid Measures Assessment - Conduct a primary and secondary assessment to determine if there are any life- threatening injuries. Treatment  Activate EMS system, if necessary.  Do not attempt to manipulate or “straighten out” an injury.  Expose the injury by removing clothing covering the area.  Control bleeding associated with open fractures.  Stabilize the injury by immobilizing the bones above and below the joint.  Check distal pulse of affected limb.  Treat for shock.  Do not elevate legs if injury is to the lower extremities.  If treating multiple victims with fractures, treat the most life threatening fractures first (e.g., spinal fractures, fractures involving pelvis, fractures that could lead to internal bleeding in the body cavity), injured arm to the victim’s body, etc.). 33 Burns Introduction A burn is an injury caused by heat, chemicals, or electricity. Burns can involve just the outer-most layer of the skin or go deeper into structures below the skin including muscle, bone, nerves, and blood vessels. Along with physical damage, victims with burns can also experience great pain and emotional trauma from the injury. Victim assessment Prior to any first aid measures, no matter how extreme the burn, a victim assessment including primary and secondary surveys should be conducted. Only when immediate life- threatening conditions have been addressed, should the officer’s attention be directed to first aid treatment for the burns themselves. Severity - Burns involving the skin are classified according to the depth of the burn in the tissue. Classifications include: first-degree burns, second-degree burns, third-degree burns, and fourth-degree burns. First-degree  Damage only to the epidermis (outer-most layer of the skin)  Also referred to as superficial burns  Skin appears red  Can be very painful  Damage usually heals without scarring  Example: mild sunburn Second-degree  Damage to the epidermis and the dermis (second layer of the skin containing nerves, hair follicles, and sweat glands)  Also referred to as partial thickness burns  Skin appears red and mottled (spotted)  Accompanied by blisters (plasma and fluid released from tissue that rises to top layer of skin)  May involve swelling  Causes intense pain  May produce slight scarring Third-degree  Damage to the epidermis, dermis, and into fatty layer and muscle beneath the skin  Also referred to as full thickness burns  Skin appears dry, leathery, and discolored (white, brown, or black)  May be extremely painful or the victim may experience little pain if nerve endings have been destroyed  May require skin grafting to heal  Causes dense scar formation Fourth-degree  Damage to bone and underlying organs 34 Burns, Continued First aid measures The most common types of burns are thermal burns, chemical burns, and electrical burns. The following table provides a description along with appropriate first aid measures for each: Description / First Aid Measures Thermal Burns  Caused by direct heat Possible causal agents Chemical Burns  Caused by acids or alkalis coming into contact with the skin  Most frequently occurs in industrial settings NOTE: Bandage should hold dressing in place and protect the area from contaminants. Bandaging too tightly may not only cause pain but also restrict swelling. Electrical Burns  Occur when the body becomes a conduit for electrical current  Sources include: Electrical Burns, continued  May cause extensive internal injuries NOTE: Entrance and exit wounds caused by electrical current may be difficult to see initially. They will be found in different locations on the victim’s body. For example, if the victim touches a live wire, current may enter the body through the hand, pass through the body, and exit through the victim’s feet. Electrical current and vehicles If officers respond to calls where live power lines have fallen onto a vehicle, they should:  not touch the lines or any part of the vehicle,  instruct the occupants to remain in the vehicle, and wait for the utility company to turn off the power before taking any action.  Occupants should not be told to leave the vehicle unless life-threatening circumstances exist (e.g., vehicle fire). 35 Medical Emergencies In this chapter. This chapter will focus on basic first aid measures for a variety of medical emergencies and conditions peace officers as EMS First Responders may encounter. Cardiac Emergencies Introduction A cardiac emergency can range from a victim experiencing shortness of breath or palpitations to full cardiac arrest. Swift action is necessary on the part of peace officers to prevent death or permanent neurological injury. Heart attack is a common term describing minor to severe conditions. Minor conditions include blockage of blood or lack of oxygen to heart tissue, and varying levels of pain. If the victim does not receive appropriate care immediately, the victim’s chances of survival are greatly reduced. Coronary artery disease (CAD) (often referred to as coronary heart disease) is a disease where fatty deposits build up in the walls of the arteries that feed the heart’s muscle. If an artery becomes blocked, the heart muscle will be deprived of blood and oxygen. Other causes of cardiac emergencies Along with coronary heart disease, there are a number of other conditions that can lead to cardiac emergencies. Cardiac arrest may also be caused by:  drowning,  electrocution,  suffocation,  choking,  drug overdose, or  allergic reaction. Indicators of Cardiac Emergency  Chest Pain - Crushing, dull, or heavy persistent pain (i.e., angina). Sensation of squeezing or pressure  Radiating Pain - Pain, pressure, or discomfort moving:  Vital Signs - Difficulty breathing or shortness of breath. Abnormally slow or fast pulse.  Mental Status - Anxiety or feeling of impending doom. Irritability or short temper. Denial of indicators  Other - Profuse sweating, Cool, moist, pale or ashen skin. Nausea or heartburn. First aid measures 36 Although the indicators of a cardiac emergency resemble the indicators of a number of other medical conditions (e.g., heartburn), peace officers should always first assume that a cardiac emergency exists, activate the EMS system (if not already activated), and take appropriate first aid measures. First Aid Measures for Cardiac Emergencies, continued Assessment - Conduct primary and secondary surveys. Treatment  Activate EMS system.  Place the victim in a comfortable position (e.g., seated, supine, etc.).  Keep the victim calm and still (even if the person denies indicators of a heart attack).  Provide care to prevent shock.  Maintain victim’s body temperature.  Continue to monitor victim’s CABs and provide reassurance until EMS personnel arrive. Medications Some victims with existing cardiac conditions may be taking prescription medications for that condition. Officers should never administer any medications, prescribed or otherwise. If victims are oriented enough to ask for or decide they need their prescribed medication, peace officers may allow a victim to take them. Officers may assist the victim if required (i.e., removing medication from its container and placing it in the victim’s hand). 37 Respiratory Emergencies Introduction Respiratory emergencies may range from victims who are having breathing difficulty, but nevertheless are breathing adequately, to victims who are not able to breathe at a level that will sustain life. Adequate breathing Normal breathing rate is determined based on the person’s age. Age Breathing Rate Adult (8 years and older) 12-20 breaths/minute Child (1-8 years) 15-30 breaths/minute Infant (newborn - 1 year) 25-50 breaths/minute Causes of inadequate breathing There are numerous possible causes that could lead to inadequate breathing and potential respiratory arrest (when breathing stops completely), including:  existing illness (e.g., emphysema, asthma),  allergic reaction (causing swelling of the throat),  cardiac emergency,  drowning,  suffocation,  obstructed airway,  body positioning that restricts breathing (i.e., positional asphyxia),  drug overdose, or  hyperventilation. Breathing Rate  Abnormally fast (i.e., hyperventilation) or slow  Sporadic or irregular breaths Labored Breathing  Increased effort by the victim  Breathing appears shallow or very deep  Little or no air is felt at the nose or mouth  Uneven or little chest movement Breathing Sounds  Wheezing, gurgling, deep snoring sounds  No breathing sounds Coloring  In advanced stages, lips, nail bed, skin will appear blue-grey in color due to lack of oxygen (i.e., cyanosis) Mental Status  Anxious  Fearful  Panicky 38 Respiratory Emergencies, Continued First aid measures If a peace officer suspects that a victim is experiencing a respiratory emergency, the officer should activate the EMS system (if not already activated) and take appropriate first aid measures. First Aid Measures for Respiratory Emergencies Assessment - Conduct primary and secondary surveys. Check for breathing. Look for even rise and fall of the victim’s chest. Listen for air entering and leaving the victim’s nose and mouth. Feel for air moving into and out of the victim’s nose and mouth. Treatment  Activate EMS system, if necessary.  Place the victim in a position of comfort (e.g., seated, supine, etc.).  If victim is unconscious, place in the recovery position, if appropriate.  Keep the victim calm and still.  Allow the victim to take prescribed medications (e.g., inhaler).  Loosen any restrictive clothing.  Provide care to prevent shock.  Maintain victim’s body temperature.  Continue to monitor victim’s CABs and provide reassurance.  Be prepared to begin rescue breathing if necessary. 39 Seizures Introduction - A seizure is the result of a surge of energy through the brain. Instead of discharging electrical energy in a controlled manner, the brain cells continue firing, causing massive involuntary contractions of muscles and possible unconsciousness. If only part of the brain is affected, it may cloud awareness, block normal communication, and produce a variety of undirected, unorganized movements. Epilepsy is a term for a convulsive disorder which causes brief, temporary changes in the brain’s electrical system, known as a seizure. Indicators of a seizure Indicators of a seizure may include:  staring spells,  disorientation,  lethargy,  slurred speech,  staggering or impaired gait,  tic-like movements,  rhythmic movements of the head,  purposeless sounds and body movements,  dropping of the head,  lack of response,  eyes rolling upward,  lip smacking, chewing, or swallowing movements,  partial or complete loss of consciousness, or  picking at clothing NOTE: Individuals with epilepsy may exhibit characteristics similar to the effects of drug use or alcohol intoxication. Actions When officers encounter someone experiencing a seizure, the officers should:  look for medical alert bracelets, necklaces, or other terms of medical identification.  not restrain them.  move objects out of the way which could harm them.  cushion the person’s head.  keep people away.  turn the person on his/her side.  never put any object in the mouth. After the seizure has ended, individuals may experience a period of post seizure confusion. Officers should remain with the individual until the individual is reoriented to the surroundings or in the care of a responsible person. 40 NOTE: Individuals with epilepsy often exhibit behavior similar to the effects of drug use or alcohol intoxication. NOTE: Convulsions, confusion, and episodes of agitated behavior during an episode should not be perceived as deliberate hostility or resistance to the officer. Seizures, Continued Medications - Depriving medications could trigger a seizure. Officers should be guided by agency policy regarding the administering of prescribed medications. Examples The following examples illustrate officer interactions with people experiencing a seizure. Example: While on patrol, two officers were stopped by a man who stated that there was a woman on the sidewalk who seemed to be “sick or something.” When the officers approached, they saw the woman on the ground. She was unconscious and jerking back and forth. One of the officers recognized that the woman was experiencing a seizure and told his partner to keep everyone else away. After a couple of minutes the woman’s actions stopped. When the woman regained consciousness, the officer approached her and reassured her that it was all right. The woman appeared to be dazed and confused so the officers remained with her until she was able to leave safely. Example: An officer was called to a parking lot where a man appeared to be wandering about in a daze. The man was staring straight ahead and seemed to be moving aimlessly, oblivious of his surroundings. The man did not respond to the officer’s questions and instead continued smacking his lips and picking at his shirt. When the officer attempted to take hold of the man’s arm, the man began to struggle and became agitated. The officer failed to recognize that the man was experiencing a partial seizure and assumed that he was under the influence of drugs. The officer’s actions caused a potential for injury. 41 Strokes Introduction A victim experiences a stroke (i.e., cerebrovascular accident (CVA)) when an artery providing blood to the brain is blocked. A stroke can also be caused by a ruptured blood vessel in the brain creating pressure on brain tissues. Indicators of Stroke  Mental Status  Mobility  Convulsions  Vision  Communication  Other First Aid Measures for Stroke If a peace officer suspects that a victim has experienced a stroke, the following first aid measures should be taken. Assessment  Conduct primary and secondary surveys.  Activate the EMS system (if not already activated). Treatment  If conscious, elevate head and shoulders slightly (semi-sitting position).  If unconscious, and appropriate, place in recovery position on affected side.  Activate the EMS system (if not already activated).  Continue to monitor CABs and maintain an open airway.  Reassure victim.  Take appropriate actions to prevent shock.  Protect any numb or paralyzed areas from possible injury.  Do not give victim anything by mouth. Diabetic Emergencies Introduction The basic source of energy within the human cell is glucose. Glucose is circulated throughout the body in the bloodstream. In order for glucose to pass from the bloodstream into the body’s cells, insulin, a hormone produced by the pancreas, must be present. An imbalance of insulin in the body and glucose in the bloodstream can lead to life- threatening conditions. Diabetes is a condition brought on when the body does not produce a sufficient amount of insulin. Diabetes can occur at any age. Insulin shock and diabetic coma An improper level of insulin in the body can lead to two potentially dangerous conditions: insulin shock and diabetic coma. 42 Indicators There are a number of different indicators of a possible diabetic emergency. The following table presents a comparison of the indicators of insulin shock and diabetic coma: Indicators of a Diabetic Emergency Insulin Shock Diabetic Coma Onset  Skin  Breathing  Mental Status  Pulse  Other Diabetic Emergencies, Continued Diabetic emergency vs. other conditions There are a number of indicators of a diabetic emergency that are similar to indications of alcohol intoxication or substance abuse.  Aggressiveness  Combativeness  Uncooperative behavior  Confusion, dazed appearance  Decreased level of consciousness  Impaired motor skills Peace officers should never assume that a person exhibiting these indicators is intoxicated without further questioning and assessment. First Aid Measures for Diabetic Emergencies Because it can be extremely dangerous and life-threatening if left untreated, a possible diabetic emergency must be thoroughly assessed and first aid measures taken immediately. Along with activating the EMS system (if not already activated) officers should take the following first aid measures. Assessment  Ask questions to determine if victim has exhibited any indications of a potential diabetic emergency.  Look for medical alert jewelry or other indicators that the person may be diabetic (e.g. wallet identification card, oral medications, insulin in the refrigerator, etc.).  Conduct primary and secondary surveys. Treatment  If unconscious:  If conscious, NOTE: Types of oral glucose include: - table sugar (not a sugar substitute) dissolved in water. - orange juice. - honey. - hard candy placed under the tongue. 43 Poisoning and Substance Abuse Introduction A poison is any substance introduced to the body that causes damage. Children are the most common victims of poisoning. Adults may become victims of poisons from their environment as well as by overdoses of medications or substance abuse. Poison identification Peace officers acting as EMS First Responders should make every effort to obtain pertinent information from the victim, family members, and bystanders as well as through their own observations. Officers should attempt to determine:  what substance or combination of substances is involved,  when was the victim exposed to the substance,  how much of the substance the victim was exposed to,  length of time the victim was exposed,  what effects the victim has experienced since the exposure, and  what if any interventions others (e.g., family members, friends, etc.) have already taken. Officers should also look for indications of:  medical problems (e.g., bottles of medications, medical alert jewelry, etc.),  existence of injuries, and/or  evidence of alcohol or illegal drug use (e.g., drug paraphernalia, bottles, etc.). Officer safety Peace officers responding to medical emergencies involving poisons should take appropriate precautions against exposing themselves to the substance as well. Officers should:  not enter any environment containing poisonous gases or fumes until the area has been well ventilated.  use care when handling hypodermic needles or other sharp objects that may be contaminated.  not take any actions that could cause them to become victim’s of the substance. Manner of exposure Poisons can be taken into the body in various ways, either accidentally or deliberately. Ingestion - Swallowing the substance  Medications  Illegal drugs  Alcohol  Household or industrial chemicals  Petroleum products  Improperly prepared food 44 Poisoning and Substance Abuse, Continued Inhalation - Breathing in the substance in the form of gases, vapors, or fine sprays  Carbon monoxide  Household or industrial chemicals  Petroleum products Absorption - Taking in the substance through unbroken skin or membranes  Insecticides  Agricultural chemicals  Plant materials (e.g., poison ivy) Injection - Through deliberate or accidental punctures to the skin  Illegal drugs  Medications Indicators of Poisoning Specific indicators will vary greatly depending on the poisonous substance involved. The following table presents a number of indicators that may aid in determining the manner in which the poison was taken into the body: Ingestion  Possible burns around the mouth or hands  Unusual stains or colors on skin or mouth  Strong odor on victim’s breath  Difficulty breathing  Sudden unexplained, severe illness  Vomiting, abdominal cramping Inhalation  Dizziness  Headache  Nausea, vomiting, abdominal cramping Absorption  Itching  Redness, rash, or some other form of skin reaction  Increased skin temperature  Headache  Eye irritation  Allergic reaction Injection  Swelling at injection site  Redness of affected skin NOTE: Some individuals may have a systemic (i.e., whole body) reaction when exposed to certain substances. One symptom of a systemic reaction is anaphylactic shock, a condition that causes the airway to swell, making breathing difficult if not impossible. 45 Poisoning and Substance Abuse, Continued First Aid Measures for Poisoning Just as the indicators vary, first aid measures for treating a poisoning victim vary based on the specific type of poison and how it was ingested. For serious medical emergencies, the officer should activate the EMS system (if not already activated). If a peace officer, acting as an EMS First Responder, suspects that a victim has been exposed to a poison, that officer should take the following first aid measures: Assessment  Determine the victim’s level of consciousness.  Conduct primary and secondary assessments. (Look for signs of swelling, redness, puncture sites, etc.)  Attempt to identify the poisonous substance. Treatment  Activate the EMS system.  If necessary, remove victim from source of poison (gases, vapors, plant material, etc.).  If victim is unconscious, place in a recovery position, if appropriate.  Contact poison control center for treatment advice.  If exposure has been through absorption: o flood affected areas with water, and o wash affected areas with soap and water.  Take precautions to prevent shock.  Continue to monitor victim’s CABs. Alcohol and substance abuse There are a number of indicators specific to poisonings caused by alcohol and/or substance abuse, of which officers should be aware. Indications of withdrawal from alcohol or drugs can include, but are not limited to:  confusion,  hallucinations or psychotic behavior,  blackouts (i.e., loss of short term memory),  altered mental status,  tremors or shaking,  profuse sweating, or  increased pulse and breathing rates. Certain types of drug abuse can also be associated with violent outbursts and aggressive behavior. Officers should take necessary precautions to protect themselves and others when assisting an individual suspected of drug or alcohol abuse. 46 Temperature Related Emergencies Introduction The body must generate heat in order to maintain a constant internal body temperature. Excess heat is released through the lungs and skin. If the body is not able to generate enough heat or generates too much heat, the body’s systems may shut down, creating a life-threatening condition. Cold related emergencies Hypothermia occurs when the body’s internal temperature drops to the point where body systems are affected. Hypothermia can range from mild to severe due to a number of factors:  length of exposure to cold temperatures,  condition of victim’s clothing (wet or dry),  age of victim (elderly and very young are more susceptible),  existence of underlying illnesses or disorders (e.g., circulatory problems, infections/fever),  traumatic injury (e.g., head injuries, etc.), or  alcohol consumption. NOTE: Hypothermia can develop even in temperatures that are above freezing. Indicators of Hypothermia Mild/Moderate Hypothermia  Violent shivering  Numbness  Fatigue  Forgetfulness  Confusion  Cold skin  Red skin color  Loss of motor coordination  Rapid breathing and pulse Severe Hypothermia  Lack of shivering  Rigid muscles and joints  Slow shallow breathing  Irregular, weak, slow pulse  Dilated pupils  Decreased level of consciousness leading to unconsciousness  Unwilling or unable to do simple activities  Not oriented to person, place, or time  Slurred speech  Blue-grey skin color NOTE: Unconscious victims with hypothermia may appear clinically dead due to stiffness and extremely low pulse and respiration rates. 47 Temperature Related Emergencies, Continued First aid measures for hypothermia First aid measures are dependent upon whether the victim’s condition is mild or severe. First Aid Measures for Hypothermia Mild/ Moderate  Move victim to a warm environment (e.g., patrol vehicle).  Remove any wet clothing and replace with dry.  Rewarm victim slowly.  Provide care to prevent shock.  Monitor the victim’s CABs.  If victim can swallow easily, give warm liquids (e.g., water).  Do not give alcoholic or caffeinated beverages, or nicotine because they can further hinder circulation.  Keep the victim moving to increase circulation. Severe Hypothermia  Activate the EMS system (if not already activated).  Determine the victim’s level of consciousness.  Conduct primary and secondary surveys.  If victim has a pulse but is not breathing, begin rescue breathing.  If victim has no pulse and is not breathing, begin CPR. NOTE: If the victim cannot be moved, take necessary measures to keep the victim from losing more body heat (e.g., wrap in blankets, etc.). Frostbite Exposure to cold temperatures can also lead to cold-related injuries to parts of the body. Injuries that are the result of cold or freezing tissue include frostnip and frostbite. Areas most commonly affected by frostbite are:  ears,  face and nose,  hands,  feet and toes. Indicators First Aid Measures Frostnip  Superficial freezing of skin’s outer layer  Numbness  Pale skin color  Skin feels flexible to the touch  Tingling or burning sensation to the area upon warming Temperature Related Emergencies, Continued 48 Indicators First Aid Measures Frostbite  Freezing of tissue below the skin’s surface  Skin feels stiff to the touch  Pale, grey-yellow, grey-blue, waxy, blotchy skin color  Pain or aching sensation to the area upon warming NOTE: Do not rub the affected area. Damage may be caused by ice crystals that have formed below the surface of the skin. NOTE: Do not allow the frozen area to refreeze after warming. Refreezing can cause extensive tissue damage. Heat cramps and heat exhaustion If the body is unable to get rid of excess heat, the body’s internal temperature can rise to a level that can cause pain, organ damage, or even death. Heat cramps can strike when the body loses too much salt due to prolonged perspiration. Heat exhaustion is a condition that is more serious than heat cramps. It is a form of shock that can occur when the body becomes dehydrated. Once a person who is exposed to heat becomes thirsty, that person may already be suffering from dehydration. In both cases, the person will have a normal body temperature and be able to think clearly. First aid measures for heat cramps and heat exhaustion Heat cramps and heat exhaustion can be relatively minor illnesses if they are recognized and treated rapidly. The following table identifies the indicators as well as first aid measures for each: Indicators First Aid Measures Heat Cramps  Painful muscle spasms usually in the legs or abdomen  Lightheadedness  Weakness Temperature Related Emergencies, Continued Heat Exhaustion  Profuse sweating  Dizziness  Headache  Pale, clammy skin  Rapid pulse  Weakness  Nausea and vomiting Heat stroke 49 If heat exhaustion is not recognized and treated promptly, heat stroke may set in. Heat stroke occurs when the body’s internal temperature rises abnormally high. Heat stroke is a life-threatening condition requiring immediate attention. Indicators / First Aid Measures Heat Stroke  Red, hot, dry skin  Rapid, irregular pulse  Shallow breathing  Confusion  Weakness  Possible seizures and/or unconsciousness NOTE: Heat stroke can affect children or the elderly who have circulatory problems, even when they are not exposed to extreme heat. NOTE: Dry hot conditions, versus heat with high humidity, can bring on less fatigue. For this reason, individuals may remain in a dry hot environment longer and become more susceptible to heat related illnesses. Stings and Bites Introduction - Insect stings, spider bites, and snake bites can all be sources of injected toxins. Certain insects, spiders, and snakes can inject toxins that cause serious consequences if not treated rapidly. Anaphylactic shock Anaphylaxis (i.e., anaphylactic shock) is a severe, life-threatening allergic reaction caused by exposure to certain allergens. Exposure to an allergen (via insect stings, foods, etc.) can cause:  blood vessels to dilate leading to a sudden drop in blood pressure, and  swelling of the tissues that line the respiratory system causing an obstructed airway. First aid measures Epinephrine - is a hormone produced by the body. When administered as a medication soon after exposure, epinephrine will constrict blood vessels and dilate the bronchioles helping to open the victim’s airway. Individuals who are subject to anaphylaxis often carry prescription epinephrine to use if such a reaction occurs. Insect stings and bites 50 Insects that sting include wasps, hornets, bees, yellow jackets, and fire ants. Insects that bite include mosquitoes, lice, gnats, and ticks. In either case, most insect stings and bites are little more than an irritation to the victim; unless they produce a venom which induces anaphylaxis. Indicators First Aid Measures Usual Reaction  Local swelling  Minor pain  Itching Allergic Reaction  Itching  Burning sensation  Hives  Swollen lips and tongue  Difficulty breathing  Respiratory failure Stings and Bites, Continued Spider bites Although most spiders are harmless, the venom from the Black Widow and Brown Recluse spiders can cause serious illness. The following table provides information regarding first aid measures for treating the victim or bites from these spiders: Description Indicators / First Aid Measures Black Widow - Marked by a real, hourglass shaped spot on its abdomen.  Dull pain within 15 minutes of bite  Headache  Chills  Sweating  Dizziness  Nausea and vomiting Brown Recluse - Marked by a brown or purplish violin-shaped mark on its back  Painless ulcer at site where bitten  Ulcer gradually increases in size (bull’s-eye appearance)  Chills  Aches  Nausea Snake bites - Most native snakes in California are not poisonous. The exceptions are the Rattlesnake and poisonous snakes that have been brought into the state. Bites from poisonous snakes can be extremely serious but rarely fatal. Indicators / First Aid Measures  Pain, redness, and swelling which begins quickly after bite  Fang marks  Shortness of breath 51  Tingling around victim’s mouth  Bloody vomiting (appearance of coffee grounds)  Shock  Coma Stings and Bites, Continued Animal and human bites Although animal and human bites do not involve toxins or venom, they can become infected if not treated properly. The victim of an animal bite may also be at risk of rabies if the bite as caused by an infected animal. Indicators / First Aid Measures  Pain, redness, swelling at the site  Damage can range from puncture wound of skin to severe laceration or avulsion of tissue. NOTE: If possible, an attempt should be made to identify the circumstances that led to the bite and locate the animal for rabies testing. 52 Childbirth Officers must have a basic understanding of first aid measures to assist before, during, and after delivery in an emergency situation. This chapter will focus on basic first aid measures for assisting a woman during childbirth. Normal Labor and Childbirth Introduction - Only the woman herself can deliver her infant. If called upon to assist during normal childbirth, it is the officer’s role to activate the EMS system, determine if the woman can be transported prior to the birth, and provide support as the woman delivers the infant. Transport prior to birth One of the first decisions the assisting officer will need to make is whether or not to arrange for transport to a medical facility prior to delivery of the infant. The woman can be safely transported only if she is in the first stage of labor (not straining, contractions are still farther apart, and there are no signs of crowning). NOTE: If transport is safe, continue to monitor the woman while waiting for EMTs to arrive at the scene. Imminent birth If any of the following conditions exist, the woman is entering the second stage of labor and birth may be imminent. The woman should not be transported. Indications that birth may be imminent include:  contractions that are occurring less than two minutes apart (five minutes if second or subsequent birth),  the woman feels an urgent need to bear down, and/or  crowning is present. Complications in Childbirth Introduction - Although most deliveries take place without difficulty, complications may occur. At such times, it is extremely important to activate the EMS system, provide emotional support and reassurance to the woman and take appropriate first aid measures until additional EMS personnel arrive at the scene. Excessive bleeding prior to delivery The presence of some blood prior to the beginning of delivery is normal. If bleeding is excessive, it may be an indication of a complication. There are a number of possible causes for this condition. 53 Complications in Childbirth, Continued Indicators / First Aid Measures  Profuse bleeding from vagina  Mother may or may not experience abdominal pain. Newborn fails to breathe A newborn should begin breathing on its own within 30 seconds after birth. If it fails to breathe, rubbing the infant’s back or tapping the infant’s feet may stimulate spontaneous respiration. If the newborn still fails to breathe on its own, rapid first aid measures are required. The following actions should be taken: First Aid Measures  Circulation - Check for a brachial pulse; If there is no pulse, begin CPR immediately. If there is a pulse, then check the airway.  Airway - Open the infant’s airway; do not overextend the head and neck. This could close the airway or damage the infant’s trachea.  Breathing – Check for breathing looking and listening for breathing; if none, provide two slow small breaths (“puffs”). NOTE: For additional information regarding infant rescue breathing and CPR, refer to Basic Life Support.
