The public is encouraged to use an AED and CPR if someone collapses and shows no signs of life, like breathing or gasping. Time is critical in these situations. When out-of-hospital cardiac arrest (stopping of the heart) occurs, the chance of survival without intervention decreases by 10% per minute. After 4 to 6 minutes without treatment of cardiac arrest, brain death occurs and by 10 minutes without treatment, the chance of survival is next to none.
An Automated External Defibrillator (AED):
- Is a small portable device that can analyze the electrical activity of a person’s heart to determine if the heart would benefit from applying energy (a "shock")
- Works by stopping the uncoordinated electrical activity of the heart, giving the heart a chance to re-establish a regular rhythm
Public Access Defibrillators aid in the CPR treatment by helping the user with verbal instruction and require no formal training to be used. The combination of AED use and CPR can increase the chance of survival by 75%.
