AED are small, easy to use machines that allow bystanders to help victims of cardiac arrest.  Applied to unresponsive victims, AED are attached by large stickers applied to the chest.  Then the AED analyzes the cardiac rhythm of the victime to determine if a shock is advised.  If a shock is advised the AED prompts the rescuer to shock the victim by pressing a button.

AED’s are found in many public places such as libraries, parks, schools, and the like.  Many companies also have them installed in their buildings, such as grocery stores and department stores.
