Unlike regular [[defibrillator]]s, an automated external defibrillator (AED) requires minimal training to be used (or even no training). That is possible because all AEDs approved for use in the [[United States]] and many other countries use an electronic voice to prompt users through each step. Many AEDs now include visual prompts in case of a [[hearing impairment|hearing impaired]] user. 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).

An AED 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&nbsp;lbs (25&nbsp;kg) in weight or under age 8.
