It is important to implement good quality chest compressions for cardiopulmonary resuscitation (CPR). This manikin study examined the effects of different compression rates on chest compression depth variables using a metronome sound guide. Fifty sixth-year dentistry students participated in the study. Each participant performed CPR at 3 different compression rates, 110, 100, and 90 compressions per min (pace-110-g, pace-100-g, and pace-90-g) for 2 consecutive one-minute sets with a ten-second break between the sets. The percentage of compressions deeper than 5 cm at pace-110-g decreased significantly from 22.1 ± 4.7% in the first set to 16.7 ± 4.4%* in the second set (*p<0.05 vs. the first set). However, no significant differences were observed between the first and second sets at pace-100-g and pace-90-g. The results obtained for pace-110-g were compared in detail by gender. In the male group, the percentage of compressions deeper than 5 cm was 43.5 ± 7.5% in the first set, and this decreased significantly to 34.6 ± 7.6%* in the second set (*p<0.001 vs. the first set). However, the percentage of compressions deeper than 5 cm in the female group was 2.3 ± 1.6%* in the first set and 0.2 ± 0.2%* in the second set (*p<0.05 vs. male). Our study demonstrated that the compression pace of 110 compressions per min was inadequate to provide chest compressions of an appropriate depth, which decreased rapidly. Therefore, limiting the rate of compressions to within a certain number per min may contribute to minimizing deteriorations in compression depth in hands-only CPR.
