An appropriate compression pace is important for securing the quality of hands-only CPR--a manikin study. Hiroshima J Med Sci. 2014 Sep;63(1-3):7-11 Authors: Shimizu Y, Tanigawa K, Ishikawa M, Ouhara K, Oue K, Yoshinaka T, Kurihara H, Irifune M Abstract 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 ...
