Automated External Defibrillator - Quick and Easy reference

An automated external defibrillator (AED) is a

lightweight, portable device that delivers an

electric shock through the chest to the heart. 



Sudden Cardiac Arrest occurs when the heart malfunctions and

stops beating unexpectedly. If not treated within

minutes, it quickly leads to death.

Most SCAs result from ventricular fibrillation (VF). 



How does an AED work?

A built-in computer checks a victim’s heart rhythm

through adhesive electrodes. The computer calculates

whether defibrillation is needed. If it is, a recorded

voice prompts the rescuer to press the shock button

on the AED. This shock momentarily stuns the heart

and stops all activity. It gives the heart the chance to

resume beating effectively. Audible prompts guide the

user through the process. AEDs advise a shock only

for ventricular fibrillation or another life-threatening

condition called pulseless ventricular tachycardia.



Non-medical personnel such as police, fire service

personnel, flight attendants, security guards and other lay

rescuers who have been trained in CPR can use AEDs.

Although formal training in the use of an AED is not

required, it is recommended to help the rescuer increase

their comfort and level of confidence. However, AEDs

are intended for use by the general public. Most AEDs

use audible voice prompts to guide the user through the

process.
