An automated external defibrillator, called AED, is a portable medical device that can diagnose specific arrhythmias and administer electric shocks to defibrillation. It is a medical device that can be used by non-specialists to rescue patients in cardiac arrest. During cardiac arrest, defibrillation and cardiopulmonary resuscitation with an automated external defibrillator (AED) during the "golden four minutes" of optimal resuscitation time is the most effective way to prevent sudden death.

In the United States, an average of one acute cardiac arrest occurs every minute, and about 540,000 people die of sudden cardiac death in Our country every year. Acute cardiac arrest, or SCA, is the leading cause of death in humans. The out-of-hospital incidence of SCA accounts for 2/3 of all cases. Cardiopulmonary resuscitation and defibrillation must be performed within 3-5 minutes to save sudden cardiac death. The chance of survival decreases by 10% for every minute of delay in defibrillation! 

Since rescue time is so precious, how do people get first aid if they suddenly die of heart attack in a public place? The medical community believes that installing automatic external defibrillators in public places is a way to improve the survival rate of sudden cardiac death.

AED is a foolproof cardiac defibrillation device for non-medical personnel. It is very easy to operate and has a voice prompt for each step of operation. Non-medical personnel need a little training to become proficient in using it. It has been proven that installing AEDs in public places doubles the chances of survival for SCA patients.
