CPR and AED Usage
Table of Contents
1. CPR
cardiopulmonary resuscitation 30:2 compressions : ventilations
2. Chest compressions
- lower half of sternum
- compress 4-6cm
- hard and fast
- 100-120 per minute
- count: 1 and 2 and … 5; 1 and 2 and… 10; to 30
- allow complete chest recoil
- if tired, 10s rest between 100 comps
3. Rescue breath (ventilation)
- pinch nose; seal lips around mouth
- 2 quick breaths (1s)
- enough air to make chest rise (400-600mL)
- release nose
4. AED
heart rhythm interpretation advises operator if shock is needed delivers shock used only when C is: unconscious + not breathing + no pulse
4.1. rhythms
- shockable: ventricular fibrillation (VF)
- irregular, uncoordinated rhythms
- deteriotes to asystole in 8-10m
- non-shockable
- normal sinus rhythm
- asystole (flat line)
4.2. environmental dangers
- water (rain)
- metal surfaces
- flammable gas
4.3. chest preparation
- move jewelry
- shave excess chest hair
- check for pacemaker
- place 4 fingers away
- remove medication patches if interfering
- wipe excess sweat
4.4. placement
right side, below collarbone - 8cm away left side, below & left of nipple minimal interruption to chest compressions
4.5. procedure
- turn on
- place pads
- plug pads in
- "Analyzing heart rhythm"
- don't touch C - spread arms, "stand clear"
- "Shock advised"
- "Deliver shock now"
- "No shock advised"
- restart CPR until next HR analysis
4.5.1. if chest rising
- stop CPR
- recovery position
- AED remains connected
- monitor vitals every 2m
4.6. housekeeping
- replace pads, gloves, shaver
- check battery and device status
- return to location
5. Documentation
- time of collapse
- duration of CPR
- number of AED shocks
- medical history
6. Chain of survival
- early recognition & access
- early CPR
- early defibrillation
- early ambulance
- early advanced care
