ABSTRACT ABSTRACT STUDY The ERC guidelines recommend the shortest possible compres- manual defibrillation process should be possible with a compres- sion interruptions during cardiopulmonary resuscitation. Before sion break of less than 5 seconds (Monsieurs et al. 2015). and after the shock delivery, chest compressions should be When using the corpuls3 in combination with the corpuls interrupted for a maximum of 10 seconds. A peri-shock pause cpr in an in-house study, these recommendations could be (the compression break before and after defibrillation) of a noticeably undercut. With the synchronization of the corpuls3 maximum of 10 seconds has been scientifically proven to be and the corpuls cpr, this endeavour could be further increased. associated with a higher survival rate (Cheskes et al. 2014; With synchronized device operation, the hands-off time was Sell et al. 2010). According to the ERC guidelines, the entire reduced by 16.08%. c e s n i e m i t f f o - s d n a H Illustration 1: Representation of the hands-off time of our study comparing synchronized and disconnected device operation of the corpuls3 and corpuls cpr.
