The impact of real-time chest compression feedback increases with application of the 2015 guidelines

This research by Davis and colleagues was published online in the Journal of Critical Care during August 2019.
Background:  Cardiac arrest survival depends upon chest compression quality. Real-time audiovisual feedback may improve compression guideline adherence, particularly with the more specific 2015 guidelines.
Methods:  Subjects included healthcare providers from multiple U.S. hospitals. Compression rate and depth were recorded using standard manikins and real-time audiovisual feedback defibrillators (ZOLL R Series). Subjects were enrolled before (n = 756) and after (n = 995) release of the 2015 guidelines, which define narrower compression targets. Subjects performed 2 min of continuous compressions before and after activation of feedback. The percentage of compressions meeting appropriate rate/depth targets was determined before and after release of the 2015 guidelines.
Results:  An increase in compression guideline adherence was observed with use of feedback before [68.7% to 96.3%, p < .001] and after [16.6% to 94.1%, p < .001] release of the 2015 guidelines. The proportion of subjects requiring feedback to achieve adherence was higher for the 2015 guidelines [28.6% vs. 78.5%, OR 9.12, 95% CI 7.33–11.35,p < .001].
Conclusions:  The use of real-time audiovisual feedback increases adherence to chest compression guidelines, particularly with application of the narrower 2015 guidelines targets for compression depth and rate.
