Influence of the Education in Layperson in Out of Hospital Resuscitation

Study Overview
=================
Brief Summary
-----------------
Cardiac arrest occurs frequently and the outcome after out-of-hospital resuscitation is often fatal. Disturbing is that more than half of the surviving patients suffer from permanent impairment of cognitive functions, such attention, memory and executive functioning. With all the efforts to achieve a high quality initial resuscitation management the time delay between cardiac arrest and the beginning the initial resuscitation maneuver is the main reason for the still poor outcome. To shorten this fatal time delay, current efforts of national and supranational health authorities aime at the non-medically trained lay person, who should carry out basic life support directly on the scene supported by the use of public available semi-automatic defibrillators (AED).

Detailed Description
-----------------
It is a combined retrospective and prospective observational single center study. Data of all Out of Hospital patients suffered a cardiac arrest in Zurich city will be collected according to the Utstein criteria. The aim of this study is to investigate the impact of trained police forces in the resuscitation outcome.
