Description
Background The use of mechanical chest compression devices on patients in cardiac arrest has not shown benefits
in previous trials. This is surprising, given that these devices can deliver consistently high-quality chest compressions
without interruption. It is possible that this discrepancy is due to the no-flow time (NFT) during the application of
the device. In this study, we aimed to demonstrate a reduction in no-flow time during cardiopulmonary resuscitation
(CPR) with mechanical chest compression devices following 10 min of structured training in novices.
Methods 270 medical students were recruited for the study. The participants were divided as a convenience sample
into two groups. Both groups were instructed in how to use the device according to the manufacturer’s specifications.
The control group trained in teams of three, according to their own needs, to familiarise themselves with the device.
The intervention group received 10 min of structured team training, also in teams of three. The participants then had
to go through a CPR scenario in an ad-hoc team of three, in order to evaluate the training effect.
Results The median NFT was 26.0 s (IQR: 20.0–30.0) in the intervention group and 37.0 s (IQR: 29.0–42.0) in the
control group (p<0.001). In a follow-up examination of the intervention group four months after the training, the NFT
was 34.5 s (IQR: 24.0–45.8). This represented a significant deterioration (p=0.015) and was at the same level as the
control group immediately after training (p=0.650). The position of the compression stamp did not differ significantly
between the groups. Groups that lifted the manikin to position the backboard achieved an NFT of 35.0 s (IQR:
27.5–42.0), compared to 41.0 s (IQR: 36.5–50.5) for the groups that turned the manikin to the side (p=0.074).
Conclusions This simulation-based study demonstrated that structured training can significantly reduce the no-flow
time when using mechanical resuscitation devices, even in ad-hoc teams. However, this benefit seems to be short-
lived: after four months no effect could be detected.
