Abstract
Objective. We investigated whether data collected using the Resusci Anne Skill-Reporter were comparable with those collected using the CPRmeter (cardiopul-monary resuscitation meter -an acceler-ometer feedback device used to provide high-quality chest compressions). Materials and Methods. Fifty continu-ous chest compressions were performed using a Resusci Anne SkillReporter and a CPRmeter under two conditions (Ex-periment 1: complete chest wall recoil; Experiment 2: incomplete chest wall re-coil). The conditions were defined accord-ing to visual feedback signals provided by the CPRmeter. A single healthcare worker performed 20 repetitions under each ex-perimental condition alternately. Chest compression data were collected and ana-lyzed using the Laerdal PC SkillReporting System and QCPR Review software. Results. The mean difference in chest com-pression 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 Skill-Reporter was significantly different from that of the CPRmeter. Cardiopulmonary resuscitation instructors, trainees, and re-searchers should be aware of this difference to ensure the most accurate interpretation of their training or experimental results.

Summary
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). We found that chest compression depth measured using the Resusci Anne SkillReporter differed from that of the CPRmeter (an accelerometer feedback device used to provide high-quality chest compressions) by more than 20% during CPR training sessions. We concluded that this discrepancy was not due to chance, because it exceeded the allowable error range and was observed repeatedly. N/A: not applicable, A P-value < 0.05 is presented in bold
