Automated external defibrillators (AEDs) are lightweight, battery-operated, portable devices that are simple to use. Sticky pads with sensors are attached to the chest of the person who is having sudden cardiac arrest (SCA).
The sensors send information about the person's heart rhythm to a computer in the AED. The computer analyzes the heart rhythm to find out whether an electric shock is needed. If a shock is needed, the AED uses voice prompts to tell you.
An AED will not shock in error. You cannot harm a person with an AED.
Using an AED to shock the heart within minutes of the start of SCA may restore a normal heart rhythm. Every minute counts.
Each minute of SCA leads to a 10 percent reduction in survival.
ANYBODY can use an AED to save a life. Watch this short video to find out how.
