Automatic extracorporeal defibrillators, also known as automatic extracorporeal defibrillators, automatic defibrillators, cardiac defibrillators, and dummies, are portable medical devices that can diagnose specific arrhythmias and provide shock defibrillation. They are medical devices that can be used by non professionals to rescue patients with cardiac arrest.
During cardiac arrest, the most effective way to prevent sudden death is to use an automatic external defibrillator (AED) for defibrillation and cardiopulmonary resuscitation within the "golden 4 minutes" of the optimal rescue time.
