-Cardiac refers to the heart. Arrest means stop. Sudden cardiac arrest is the sudden and unexpected loss of heart function.

-Signs of cardiac arrest include: no breathing or only gasping, no movement, and no pulse.

-Without rapid and appropriate treatment, most of these cardiac arrests will result in death. Thousands of lives could be saved through public access to automated external defibrillators.

-An automated external defibrillator (AED) is a small, portable device used to identify cardiac rhythms and deliver a shock to correct abnormal electrical activity in the heart. As a result of the sophisticated electronics in an AED the operator will only be advised to deliver a shock if the heart is in a rhythm which can be corrected by defibrillation. If a shockable rhythm is not detected, no shock can be given and the provider will be instructed to perform cardiopulmonary resuscitation (CPR) until emergency medical services arrive.

- When an AED and CPR are immediately available, the chance of survival from sudden cardiac arrest is substantially improved.  Combined with CPR, the use of an AED may increase the likelihood of survival by 75% or more.

-AEDs have been used efficiently and effectively in community settings, such as casinos, airport terminals, airplanes, shopping malls, recreation facilities, office buildings and other public locations.

-For every one minute delay in defibrillation, the survival rate of a cardiac arrest victim decreases by 7 to 10%. After more than 12 minutes of ventricular fibrillation, the survival rate is less than 5%
