Automated External Defibrillator (AED)
Early CPR can help a cardiac arrest victim, but an electrical shock (defibrillation) is required to correct the problem. The sooner an AED is used, the greater the victim's chance of survival. Each minute defibrillation is delayed; the victim's chance of survival is reduced by about 10%.
AED is an essential step in the Cardiac Chain of Survival.
