Development and validation of a medical latex glove-type real-time cardiopulmonary resuscitation feedback device.

High-quality chest compressions are critical for improving survival in patients presenting with sudden cardiac arrest. The aim of this study was to evaluate a novel medical latex glove-type real-time cardiopulmonary resuscitation (CPR) feedback device. A randomized crossover simulation study was conducted with 30 participants under three conditions: no feedback, a conventional CPR feedback device (CFD), and the novel CPR feedback device (SFD). Two-minute chest compressions were provided under each condition. The primary outcomes were the user adherence to the device-displayed guidance defined as proportion of adequate chest compressions depth (5-6 cm) and the rate (100-120 beats per minute), and the accuracy of device-displayed value based on manikin reference data. The Wilcoxon signed-rank test and exact McNemar test were used to compare. The SFD was associated with greater adherence to device-displayed feedback regarding chest compression depth: 96.7% for the SFD and 80.0% for the CFD (p value < 0.01). There was no significant difference in adherence to device-displayed feedback regarding chest compression rate: 91.7% for the SFD and 88.3% for the CFD (p value of 0.76). The SFD demonstrated a lower measurement error in chest compression depth and higher in chest compression rate compared to CFD: SFD vs. CFD - 3.6 mm vs. 4.25 mm for chest compression depth (p value 0.17), and 3.44 beats per min vs. 2.05 beats per min for chest compression rate (p value < 0.01). Chest compressions with the novel medical latex glove-type CPR feedback device resulted in a greater adherence to the device-displayed guidance on chest compression depth than the conventional device did.
