Influence of the Education in Layperson in Out of Hospital Resuscitation

Influence of the Education in Layperson Resuscitation and Preparation the Patrol Car of the City Police With Automatic External Defibrillators and Automated Ventilation Equipment on Out of Hospital Resuscitation Outcome

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).
