Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of mortality in the industrialized world. Bystander CPR before arrival of the Emergency Medical Service (EMS) is a positive predictor of survival. During the last decade, the best form of bystander CPR has been debated. Chest Compression Only CPR (CO-CPR) has been advocated as a preferable method in situations where the bystander has no previous knowledge in CPR, both because its believed to be equally efficient but also a simplified form of CPR that could lead to a higher incidence of bystander-CPR. The purpose of this study is to perform av run-in period with focus on safety and feasibility prior to the launch of a larger randomized trial which has a primary end-point of survival. This study will compare OHCA with standard CPR (S-CPR; chest compressions and rescue breaths in a 30:2 fashion) compared to CO-CPR.
