Abstract Study: Hands off time reduced with synchronised device operation, during resuscitation.

Posted by Corpuls on Jan 28, 2022 3:03:28 PM

The ERC guidelines recommend the shortest possible compression interruptions during cardiopulmonary resuscitation. Before and after the shock delivery, chest compressions should be interrupted for a maximum of 10 seconds. A peri-shock pause (the compression break before and after defibrillation) of a maximum of 10 seconds has been scientifically proven to be associated with a higher survival rate (Cheskes et al. 2014; Sell et al. 2010). According to the ERC guidelines, the entire manual defibrillation process should be possible with a compression break of less than 5 seconds (Monsieurs et al. 2015). When using the corpuls3 in combination with the corpuls cpr in an in-house study, these recommendations could be noticeably undercut. With the synchronisation of the corpulsand the corpuls cpr, this endeavour could be further increased. With synchronized device operation, the hands-off time was reduced by 16.08%.

The reduction in the compression pause is particularly evident during the perishock pause. On average, the perishock pause in synchronized mode of 2.00 ± 0.32 s is 38.23% shorter than the peri-shock pause in disconnected mode of 3.24 ± 0.71 s. This saving can be a valuable gain in time with the desired break being a maximum of 5 seconds.

When comparing the peri-shock pauses, the significant minimisation of the pause duration with synchronisation compared to disconnected device operation of corpuls3 and corpuls cpr becomes particularly clear. (Significance P < 0.001: ***)
