The automatic external defibrillator is abbreviated as AED. It is a portable medical device that can diagnose specific arrhythmia and give electric shock defibrillation. It is a medical device that can be used by non-professionals to rescue patients with cardiac arrest. In the case of cardiac arrest, only within the "golden 4 minutes" of the rescue time, defibrillation and cardiopulmonary resuscitation with an automatic external defibrillator (AED) is an effective way to prevent sudden death.


In the United States, an average of 1 case of acute cardiac arrest occurs every more than one minute. In my country, about 540,000 people die from sudden cardiac death each year. Acute cardiac arrest (SCA) is the number one killer of human deaths. The incidence of SCA out of hospital accounts for 2/3. To rescue the sudden cardiac death, CPR and defibrillation must be performed in the first 3-5 minutes. For every minute of delay in defibrillation, the chance of survival drops by 10%!

Since rescue time is so precious and people die of sudden cardiac death in public places, how should they give first aid? The medical profession believes that installing external automatic defibrillators in public places is a way to improve the survival rate of sudden cardiac death.

AED is a fool-type cardiac defibrillation device for non-medical personnel. It is easy to operate and has voice prompts for every operation. Non-medical personnel can use it proficiently with a little training.

Facts have proved that the installation of AEDs in public places doubles the survival rate of SCA patients.
