Mechanical chest compression does not seem to improve outcome after out-of hospital cardiac arrest. A single center observational trial.

Aim: Recently three large post product placement studies, comparing mechanical chest compression (cc) devices to those who received manual cc, found equivalent outcome results for both groups. Thus the question arises whether those results could be replicated using the devices on a daily routine.

Methods: We prospectively enrolled 948 patients over a 12 months period.
