Because, the AED gives the shock to the heart that most likely saves them from dieing.
Hook up the AED if immediately available; if not do CPR until the AED is ready to hook up.
Check for signs of life (breathing, pulse). If no signs of life, continue CPR.
After the shock, the AED will either say that another shock is advised or to continue CPR.
Continue CPR
You then check for breathing & pulse for a maximum of 10 seconds; if no breathing & pulse immediately start CPR and continue CPR until AED re-analyzes.
If no shock is indicated by the AED, check for signs of life. Continue CPR if no signs of life are present.
Yes you do.
CPR should be IMMEDIATELY resumed after EACH shock. After 5 cycles/2 minutes of CPR, allow the AED to analyze. If it advises no shock, resume CPR and continue this process until emergency personnel take over.
If it is a shockable rhythm, the AED will analyze and defibrillate as needed. Continue CPR when not analyzing and/or shocking.
If no shock indicated, check for signs of life; and if none continue CPR until the AED analysis's again.
An AED does two things: 1. Analyze the heart rhythm 2. If necessary- prompt the AED to deliver shock to the heart. (Shocks attempt to restart the heart). Source- I am going though CPR training and I recently learned this
Red Cross protocols on CPR and AED are: # For CPR if signs of life are not present start CPR immediately. You will need to follow the basic steps of Check Call Care. # For AED when available immediately stop CPR and attach it to the victim. Follow the directions of the AED.
Check pulse, and if no pulse, continue CPR until the AED goes to the analyze phase again.
