Abstract

«Aim: Cardiopulmonary resuscitation (CPR) quality affects survival after cardiac arrest. We aimed to investigate if a smartwatch with real-time feedback can improve CPR quality by healthcare professionals.

Methods: An app providing real-time audiovisual feedback was developed for a smartwatch. Emergency Department (ED) professionals were recruited and randomly allocated to either the intervention group wearing a smartwatch with the preinstalled app, or to a control group. All participants were asked to perform a two-minute CPR on a manikin at a 30:2 compression-ventilation ratio. Primary outcomes were the mean CCR and CCD measured on the manikin. A secondary outcome was the percentage of chest compressions meeting both the guideline-recommended rate (100–120 min1) and depth (50–60mm) of high quality CPR during a 2-min period.

Differences between groups were0 evaluated witht-test, Chi-Squaretest, or Mann–Whitney U test depending on the distribution.

Results: Eighty participants were recruited. 40 people were assigned to the intervention and 40 to the control group. The compression rates (mean SD, min1) were significantly faster (but above the guideline recommendation, P < 0.001) in the control (129.1 14.9) than in the intervention group (112.0 3.5). The compression depths (mean SD, mm) were significantly deeper (P <0.001) in the intervention (50.9 6.6) than in the control group (39.08.7). The percentage (%) of high-quality CPR was significantly higher (P<0.001) in the intervention (median 39.4, IQR p 27.1–50.1) than in the control group (median 0.0, IQR 0.00.0).

Conclusion: Without real-time feedback, chest compressions tend to be too fast and too shallow. CPR quality can be improved with the assistance of a smartwatch providing real-time feedback.»
