PAD (Public Access Defibrillation)
It's proven that AEDs can dramatically improve survival rates for sudden cardiac arrest.
In one study, published in the New England Journal of Medicine, survival rates in witnessed cases of SCA due to ventricular fibrillation reached 74 percent when the first shock was given within three minutes. Another study known as the Public Access Defibrillation Trial found that when AEDs were readily available in public places and trained bystanders were available to use them, survival rates nearly doubled over situations in which CPR alone was administered.
These studies prove what has been intuitively known for years. Although not everyone can be saved from SCA, early defibrillation by trained laypersons works in many situations. The earlier SCA victims are defibrillated, the better the outcome can be.
