AED stands for Automatic External Defibrillator. This is the type non medical personnel uses and the one found in public locations.
The are two types of heart fibrillations either of which disturbs blood flow to the brain. In fact, fibrillation is not an orderly heart beat but a quiver. The shock delivered by a Defibrillator may restore a normal heart beat and enable blood flow. It is able to detect fibrillation and actually issues spoken instructions to the person operating it. Once applied, the Defibrillator is left in place to monitor the person's heart and normally removed by Emergency Personnel.
