Automated External Defibrillator - Simplicity of Use

Simplicity of Use

Unlike regular defibrillators, an automated external defibrillator requires minima training to use. It automatically diagnoses the heart rhythm and determines if a shock is needed. Automatic models will administer the shock without the user's command. Semi-automatic models will tell the user that a shock is needed, but the user must tell the machine to do so, usually by pressing a button. In most circumstances, the user cannot override a "no shock" advisory by an AED. Some AEDs may be used on children - those under 55 lbs (25 kg) in weight or under age 8. If a particular model of AED is approved for pediatric use, all that is required is the use of more appropriate pads.

All AEDs approved for use in the United States use an electronic voice to prompt users through each step. Because the user of an AED may be hearing impaired, many AEDs now include visual prompts as well. Most units are designed for use by non-medical operators. Their ease of use has given rise to the notion of public access defibrillation (PAD), which experts agree has the potential to be the single greatest advance in the treatment of out-of-hospital cardiac arrest since the invention of CPR.

The number of people who survive sudden cardiac arrest is increasing gradually, thanks to the use of AEDs. For this reason, the Sudden Cardiac Arrest Foundation developed the National SCA Survivor Network, which provides a platform for mutual support and for engaging in the mission to help save other lives.
