General Questions
What does AED stand for?
AED stands for automated external defibrillator (or automated external defibrillation).
Whats an AED?
An AED is a device used to administer an electric shock through the chest wall to the heart. Built-in computers assess the patients heart rhythm, judge whether defibrillation is needed, and then administer the shock. Audible and/or visual prompts guide the user through the process.

How does an AED work?
A microprocessor inside the defibrillator interprets (analyzes) the victims heart rhythm through adhesive electrodes (some AED models require you to press an ANALYZE button). The computer analyzes the heart rhythm and advises the operator whether a shock is needed. AEDs advise a shock only to ventricular fibrillation and fast ventricular tachycardia. The electric current is delivered through the victims chest wall through adhesive electrode pads.

Why are AEDs important?
AEDs are important because they strengthen the Chain of Survival. They can restore a normal heart rhythm in victims of sudden cardiac arrest. New, portable AEDs enable more people to respond to a medical emergency that requires defibrillation. When a person suffers a sudden cardiac arrest, their chance of survival decreases by 7% to 10% for each minute that passes without defibrillation. AEDs save lives!

Who can use an AED?
Most AEDs are designed to be used by nonmedical personnel such as police, firefighters, flight attendants, security guards, and other lay rescuers who have been properly trained. Having more people in the community who can respond to a medical emergency by providing defibrillation will greatly increase sudden cardiac arrest survival rates.

Why does someone having a heart attack need an AED?
When a heart attack becomes a full cardiac arrest, the heart most often goes into uncoordinated electrical activity called fibrillation. The heart twitches ineffectively and cant pump blood. The AED delivers electric current to the heart muscle, momentarily stunning the heart, stopping all activity. This gives the heart an opportunity to resume beating effectively.

Will an AED always resuscitate someone in cardiac arrest?
The AED treats only a heart in ventricular fibrillation (VF), an irregular heart rhythm. In cardiac arrest without VF, the heart doesnt respond to electric currents but needs medications. The victim needs breathing support. AEDs are less successful when the victim has been in cardiac arrest for more than a few minutes, especially if no CPR was provided.

AED Use
Is an AED safe to use?
An AED is safe to use by anyone whos been trained to operate it. Studies have shown the devices to be 90% sensitive (able 90% of the time to detect a rhythm that should be defibrillated) and 99% specific (able 99% of the time to recommend not shocking when defibrillation is not indicated). Because of the wide variety of situations in which it will typically be used, the AED is designed with multiple safeguards and warnings before any energy is released. The AED is programmed to deliver a shock only when it has detected VF. However, potential dangers are associated with AED use. Thats why training Ж including safety and maintenance Ж is important.

The AHA recommends that persons who live or work where an AED is available for use by lay rescuers participate in a Heartsaver AED Course. AEDs are so user-friendly that untrained rescuers can generally succeed in attaching the pads, pressing ANALYZE (if required), and delivering shocks. However, untrained rescuers may not know when to use an AED, and they may not use an AED safely, posing some danger of electric shock to themselves and others. Also, untrained rescuers probably would not know how to respond to the victim if the AED prompts “no shock indicated.” An operator needs only to follow the illustrations on the electrode pads and the control panel and listen and follow the voice prompts (for example, “Do not touch the patient.”). An AED will deliver a shock only when a shock is advised and the operator pushes the SHOCK button. This prevents a shock from being delivered accidentally.

Are AEDs safe to use on children?
An AED should not be used on a child younger than 8 years old or weighing less than about 55 pounds. For more information on this question click here: AEDs and Children.

Will I get zapped if I shock a victim in the rain or near water?
Its remotely possible to get shocked or to shock bystanders if water is standing near or underneath the patient. Try to move the patient to a dry area and cut off wet clothing. Also be sure that the skin has been toweled dry so the electrode pads will stick to the skin. At the moment you press the SHOCK button, you must make sure that no one, including yourself (the AED operator), touches any part of the victim.

Can an AED make mistakes?
An AED will almost never decide to shock an adult victim when the victim is in non-VF. AEDs “miss” fine VF only about 5% of the time. The internal computer uses complex analysis algorithms to determine whether to shock. If the operator has attached the AED to an adult victim whos not breathing and pulseless (in cardiac arrest), the AED will make the correct “shock” decision more than 95 of 100 times and a correct “no shock indicated” decision more than 98 of 100 times. This level of accuracy is greater than the accuracy of emergency professionals.

Why do you stop CPR as the electrode pads are placed and analysis occurs?
For the AED to analyze accurately, the victim must be motionless. Sometimes there will be an agonal respiration (a
