EVALUATION ABSTRACT EVALUATION The ERC guidelines recommend the minimisation of pauses defibrillation should be performed with a compression pause during cardiopulmonary resuscitation. Chest compressions of less than 5 s (Monsieurs et al. 2015). An internal company should not be interrupted for more than 10 seconds at the trial with the corpuls3 in combination with the corpuls cpr most before and after delivery of a shock. A peri-shock pause showed pauses significantly shorter than the recommended (the compression pause before and after defibrillation) of max. limit. The synchronisation of the corpuls3 and the corpuls 10 s is scientifically confirmed to be associated with a higher cpr has been confirmed to improve this result even more. survival rate (Cheskes et al. 2014; Sell et al. 2010). Accor- Synchronised operation of the devices has been able to ding to the ERC guidelines the complete process of manual achieve a reduction of the hands-off time by 16.08%. s d n o c e s n i e m i t f f o - s d n a H Figure 1: View of the hands-off time of our study comparing synchronised and separate operation of the corpuls3 and corpuls cpr.
