Abstract

Objective. We investigated whether data collected using the Resusci Anne SkillReporter were comparable with those collected using the CPRmeter (cardiopulmonary resuscitation meter -an accelerometer feedback device used to provide high-quality chest compressions).

Materials and Methods. Fifty continuous chest compressions were performed using a Resusci Anne SkillReporter and a CPRmeter under two conditions (Experiment 1: complete chest wall recoil; Experiment 2: incomplete chest wall recoil). The conditions were defined according to visual feedback signals provided by the CPRmeter. A single healthcare worker performed 20 repetitions under each experimental condition alternately. Chest compression data were collected and analyzed using the Laerdal PC SkillReporting System and QCPR Review software.

Results. The mean difference in chest compression depth between the Resusci Anne SkillReporter and CPRmeter was 6.7 ± 1.2 mm in Experiment 1 (95% CI: 6.1~7.3) and was significantly higher in Experiment 2 (17.3 ± 1.9 mm; 95% CI: 16.4~18.2; p < 0.001).

Conclusions. The chest compression depth measured by the Resusci Anne SkillReporter was significantly different from that of the CPRmeter. Cardiopulmonary resuscitation instructors, trainees, and researchers should be aware of this difference to ensure the most accurate interpretation of their training or experimental results.
