-
-call first if suspect cardiac emergency
-care first situations are likely to be breathing emergencies
-provide care for 2 minutes and then summon advanced medical personnel if...

4. give 2 rescue breaths if no movement or breathing
5. if chest clearly rises, check for pulse no more than 10 sec
6. check for severe bleeding - Opening airway
-
-tilt adult head back
-tilt child head slightly past neutral
-tilt infant head to neutral
-if head, neck, or back injury use jaw-thrust maneuver - Checking pulse
-
-adult/child: carotid artery on neck
-infant: brachial on inside of upper arm - What to do: movement, breathing, pulse
- -place in recovery position and monitor ABC's
- What to do: first 2 rescue breaths don't make chest clearly rise
- -unconscious choking victim

- -rescue breathing
- What to do: no movement, no breathing, and no pulse
- -CPR
- Rescue Breathing: Adult
-
-pulse but no movement or breathing
-1 breath every 5 seconds
-continue for 2 minutes
-remove mask and look for movement and recheck for breathing and a pulse for no more than 10 seconds - Rescue Breathing: Child and Infant
-
-1 breath every 3 seconds
-continue for 2 minutes
-recheck for breathing, pulse, and movement - Conscious Choking Adult and Child
-
1. size up scene
2. ask "are you choking?"
-identify self and ask if can help (obtain consent)
-encourage continued coughing if coughing
3. if victim can't cough, speak, or breath have some one summon medical help
4. lean victim forward and give 5 back blows w/ heel of hand
5. give 5 abdominal thrusts - Back Blows
-
-place one arm diagonally across chest and lean victim forward
-strike victim bwt shoulder blades - Abdominal Thrusts
-
-adult: stand behind victim
-child: stand or kneel behind child
-place thumb side of fist above the navel
-give quick, upward thrusts - Continue giving back blow and abdominal thrusts until
-
-object is forced out
-victim begins to breathe or coupgh
-victim becomes unconscious - Conscious Choking Infant
-
-position infant face down on forearm
-lower infant onto thigh keeping infant's head lower than chest
-give 5 back blows
-position infant face-up along forearm
-give 5 chest thrust w/ 2 or 3 fingers just below nipple line - what if first 2 rescue breaths don't make chest clearly rise
-
-reposistion the airway by tilting head further back and try 2 breaths again
-if breaths still don't go in go to unconscious choking victim - Unconscious choking adult/child
-
-give 5 chest thrusts
-compress at rate of 100 compression per minute
-look inside victim's mouth
-if see object take it out
-give 2 breath again - Unconscious choking infant
-
-remove mask and give 5 chest compressions (2/3 fingers below nipple line)
-look for object in mouth
-see object take out
-give 2 breaths again - Cardia Chain of Survival
-
1. early recognition of emergency and early access to EMS
2. Early CPR
3. Early Difibrillation
4. Early advance medical care - Common causes of heart attack
-
-usu result from cardiovascular disease
-respiratory distress
-electrocution
-traumatic injury - Atherosclerosis
-
-depositis of cholestrol and other materials buildup on inner walls of arteries causing vessels to narrow
-when coronary arteries narrow, a heart attack may occur - Signs of Heart Attack
-
-discomfort, pressure, or pain (in chest)
-pain that comes and goes (angina pectoris)
-trouble breathing (faster than normal)
-ashen or pale skin
-sweat heavily or dizzy
-pain in left arm
-naseau/vomitting - Myocardial Infarction
-
-heart attack
-muscles of heart suffer a loss of oxygenated blood - Care for a heart attack
-
-call 911
-have victim rest
-loosen tight/uncomfortable clothing
-monitor victim
-comfort victim
-give aspirin if able
-assist w/ prescribed meds
-be prepared to give CPR or use AED - Cardiac Arrest
-
-caused by heart attack, electrocution, respiratory arrest, or drowining
-hearth stops beating or is beating to irregulary or weakly to circulate blood effectively - Signs of cardiac arrest
-
-unconsciouness
-no movement or breathing
-no pulse - CPR
-
-chest compressions circulate blood to victim's brain and other vital organs
-let chest fully recoil to normal position after each compression before starting next compression - What may happen when giving CPR
-
-break victim's ribs or seperate cartilage
-victim may vomit
-scene may become chaotic
-not all victim's survive - Adult CPR
-
-30 chest compressions and 2 rescue breaths
-two hands on the center of the chest
-compress 1.5 to 2 in.
-about 100 compressions per min - Child CPR
-
-30 compressions and 2 rescue breaths
-two hands or one on center of chest
-compress 1 to 1.5 in.
-100 compressions per min - Infant CPR
-
-30 compressions and 2 rescue breaths
-two or three fingers on center of chest
-compress .5 to 1 in.
-100 compressions per min - Two-Rescuer CPR
-
-adult: 30 compressions/2 breaths
-child: 15 compressions/2 breaths
-infant: 15 compressions/2 breaths
-15:2 ratio provides more frequent respiration for children and infants - CPR-Special Situations
-
-in stairwell, move victim to flat area (don't interrupt CPR for longer than 30 sec)
-do not interrupt CPR while a victim is being transferred to ambulance or ER - Administering emergency oxygen
- -higher concentration of O2 being deliverd to a victim can help counter the effects of a life-threatening injury or illness to the body
- Continue CPR until...
-
-another trained person arrives to take over
-AED is available to use
-too exhausted
-scene becomes unsafe
-notice an obvious sign of life - AED
-
-automated external defibrillation
-provides electric shock to heart
-disrupts electrical activity of V-fib and V-tach long enough so hearth can spontaneously develop effective rhythm on own - Hearts electricl system
-
-electrical impulses from conduction system travel through atria (upper chambers) to ventricles (lower chambers)
-under normal conditions impulse reaches muscular walls of ventricles and causes ventricles to contract forcing blood out of heart to circulate through body - Sinoatrial Node (SA)
- -normal point of origin on electrical impulses above atria
- Atrioventricular Node (AV)
-
-midway point bwt atria and ventricles
-electical impulse travels to here where pathway divides into 2 branches (right and left ventricle) - Pulse
- -contraction of left ventricle
- ECG
-
-electrocardiogram
-evaulate electrical activity of heart
-rhythms appear as series of peaks and valleys - Ventricular Fibrillation (V-fib)
-
-totally disorganzied electricl activity in the heart
-fibrillations or quiverings of ventricles
-ventricles can't pump blood and there is no movement, breathing, or pulse - Two most common rhythms initially present in cardiac arrest
-
-ventricular fibrillation
-ventricular tachycardia - Ventricular Tachycardia (V-tach)
-
-rapid contraction of the ventricles
-rate is often so fast that the heart is unable to pump blood properly
-no movement, breathing, or pulse - Asystole
-
-all electrical activity ceases b/c v-fib and v-tach were not interrupted
-asytole cannot be corrected by defibrillation - Using an AED: adult
- -provide 1 shock followed by 5 cycles (2 min) of CPR
- Possible causes of cardiac arrest in children
-
-respiratory distress (ie choking)
-traumatic injuries or accidents
-hard blow to chest
-congenital heart disease - AED precautions
-
-don't touch victim while defibrillating or analyzing
-don't use alcohol to wipe victim's chest (flammable)
-don't defibrillate around flammable materials
-don't use AED in moving vehicle
-don't use AED on victim in contact w/ water
-don't use pediatric pads on adults
-don't use AED on victim wearing nitroglycerin patch or other patches
-don't use phone or radio w/in 6 ft of AED - AED special situations
-
-around water: remove wet clothes
-implantable devices: do not place defibrillation pad directly over device
-nitrogylcerin patches: remove all patches
hypothermia: initial assessment takes longer (30-45 sec) and don't shake cause could result in v-fib
-traume
-chest hair - Using an AED: adult and child
-
-turn on AED
-wipe chest dry
-attack the pads (one on upper right chest other on lower left side)
*make sure pads aren't touching
-make sure no one is touchin victim ("stand clear")
-push analyze buttom
-push shock buttom if indicated
-after shock or if no shock is indicated give 5 cycles of CPR - 6 steps in EMS system
