Sudden out-of-hospital cardiac arrest (oCA) is a leading cause of death in the western world and only 5-8% of patients survive such an event. In addition, patients with in-hospital cardiac arrest (iCA) have a poor prognosis with a survival rate of < 30%. Defibrillation is the most effective treatment and should be performed in < 5 min in patients with oCA or in < 3 min in patients with iCA. However, its effectiveness diminishes by approximately 10% with each passing minute. The term early defibrillation is used for automated external defibrillators (AEDs) by trained public safety personal (first responder), whereas public access defibrillation describes the use of AEDs by people who have no specific AED training. Several studies in the US and in Europe have shown that first responder defibrillation will increase the number of survivors of oCA compared to the response from paramedics. This is caused by a shorter call-to-arrival time for first responders compared to paramedics. In Europe, programs for the use of AEDs exist only occasionally. Reasons for this are the lack of open mindedness, logistic and legal problems. AEDs should be installed in all public places where many people congregate as well as in hospitals. Training of all co-workers in cardiac life support and use of AEDs is essential.
