Randomized trial of the chest compressions effectiveness comparing 3 feedback CPR devices and standard basic life support by nurses

Abstract

Background: Out-of-hospital cardiac arrest is a leading cause of mortality and serious neurological morbidity inEurope.We aimto investigate the effect of 3 cardiopulmonary resuscitation (CPR) feedback devices on effectivenessof chest compression during CPR.Methods: Thiswas prospective, randomized, crossover, controlled trial. Following a brief didactic session, 140 volunteernurses inexperienced with feedback CPR devices attempted chest compression on amanikin using 3 CPRfeedback devices (TrueCPR, CPR-Ezy, and iCPR) and standard basic life support (BLS) without feedback.Results: Comparison of standard BLS, TrueCPR, CPR-Ezy, and iCPR showed differences in the effectiveness of chestcompression (compressions with correct pressure point, correct depth, and sufficient decompression),which are,respectively, 37.5%, 85.6%, 39.5%, and 33.4%; compression depth (44.6 vs 54.5 vs 45.6 vs 39.6mm); and compressionrate (129.4 vs 110.2 vs 101.5 vs 103.5 min-1).Conclusions: During the simulated resuscitation scenario, only TrueCPR significantly affected the increased effectivenesscompression compared with standard BLS, CPR-Ezy, and iCPR. Further studies are required to confirmthe results in clinical practice.
