AED generally refers to Automated External Defibrillator.
AED, also known as automated external defibrillator, automated shock device, automatic defibrillator, cardiac defibrillator, and defibrillator for dummies, is a portable medical device that diagnoses specific cardiac arrhythmias and delivers a shock to defibrillate the heart, and is a medical device that can be used by non-professionals to resuscitate cardiac arrest patients. Defibrillation and cardiopulmonary resuscitation (CPR) using an automated external defibrillator (AED) is the most effective way to stop sudden death in cardiac arrest, but only during the "golden four minutes" of the optimal resuscitation time.
Expanded:
p>Automated External Defibrillator, used when the pulse of an injured person stops. However it does not deliver a shock to an injured person who has no heart rate and has a horizontally straight ECG.?
In short, the use of a defibrillator does not by itself restore the heartbeat, as many movies and TV shows have misrepresented, but rather it stops fatal arrhythmias (such as ventricular fibrillation, ventricular flutter, and so on) by applying an electric shock, and then restores the heartbeat by reexciting the heart through an elevated cardiac pacing point. (However, in some cases patients with underlying cardiac disease may not be able to regain their heartbeat after defibrillation. (However, some patients may not be able to recover their heartbeat after defibrillation due to their underlying cardiac disease, in which case the AED will indicate that there is no indication for defibrillation and recommend immediate CPR).
