What is an Automated External Defibrillator or AED?

An AED is an electronic device that recognizes a heart rhythm that requires a shock, and then prompts the rescuer to deliver the shock simply by pressing a button. AEDs are small, lightweight, simple to operate and extremely reliable.

AEDs have been proven to be safe, reliable and effective in preventing unnecessary death from sudden cardiac arrest. Studies have clearly demonstrated that survival rates are high when defibrillation treatment is administered within the first few minutes following sudden cardiac arrest. In three studies of cardiac arrest in supervised cardiac-rehabilitation centers, more than 90 percent of victims were successfully resuscitated using AEDs.
