Brief Summary
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.

Outcome Measures
Primary Outcomes (2)
Descriptive measurement of feasibility
* Evaluation of automated inclusion and randomization * Evaluation of information of allocation to bystander * Adherence to the two protocol, bystanders (S-CPR/CO-CPR) * Validation of data collection and sources (please see appendix) * Sufficient inclusion of all OHCA during the RUN-IN study period
6 months
Descriptive measurement of safety (delay CPR)
* Delay to start of CPR due to screening for inclusion, exclusion, randomization and instructions to the witnesses (S-CPR/CO-CPR) * Correct inclusion * Correct exclusion * Proportion of patients correctly identified as cardiac arrests
6 months
Secondary Outcomes (3)
Proportions of patients with ventricular fibrillation/ ventricular tachycardia (ITT and PP)
within minutes from arrival of the EMS (day 1)
Proportion of patients who achieve return of spontaneous circulation (ROSC)
day 1
Survival to hospital admission

Eligibility Criteria
You may qualify if:
- Unconsciousness with no, abnormal or agonal breathing (suspected OHCA)
- The suspected OHCA is witnessed (seen or heard)
- Bystander has previous training in CPR
You may not qualify if:
- Age 18 or younger
- Collapse is not witnessed
- Bystander has never been trained in CPR (these bystanders should be instructed to administer CO-CPR in accordance to guidelines).
- Obvious asphyxia, i.e. drowning, strangulation, hanging
- Obvious intoxication or drug overdose
- Pregnancy
- Obvious pregnancy
- Trauma
- Bystander is unwilling to participate or to perform CPR
