目的：本研究旨在比较胸外按压心肺复苏（CPR）和传统的CPR.Methods之间的胸外按压的时间依赖性恶化：本研究涉及106和107名参与者随机分配到胸外按压心肺复苏术培训和传统的心肺复苏术培训，分别。培训结束后，立即要求参与者进行CPR 2 min，并评估其CPR技能的质量。从CPR开始，每20秒CPR周期计数胸外按压的总数和适当深度的胸外按压次数。主要结果是心肺复苏质量指数计算为胸外按压与适当的深度之间的总胸部compressions.Results的比例：胸外按压的总数保持稳定，随着时间的推移，无论是在胸外按压和传统的心肺复苏术组。然而，仅胸外按压CPR组的CPR质量指数从0- 20秒到61-80秒从86.6 +/- 25.0下降到58.2 +/- 36.9。降低幅度大于常规CPR组（85.9 +/- 25.5至74.3 +/- 34.0）。CPR质量指数的差异在61- 80 s periods.Conclusions达到统计学显著性（p = 0.003）：胸部按压与适当的深度减少更迅速，在胸部按压单纯CPR比常规CPR。我们建议CPR提供者每隔1分钟更换一次角色，以在仅胸外按压CPR期间保持胸外按压的质量。（UMIN-CTR C 000000321）（C）2010爱思唯尔爱尔兰有限公司保留所有权利。
Objectives: This study aimed to compare the time-dependent deterioration of chest compressions between chest compression-only cardiopulmonary resuscitation (CPR) and conventional CPR.Methods: This study involved 106 and 107 participants randomly assigned to chest compression-only CPR training and conventional CPR training, respectively. Immediately after training, participants were asked to perform CPR for 2 min and the quality of their CPR skills were evaluated. The number of chest compressions in total and those with appropriate depth were counted every 20-s CPR period from the start of CPR. The primary outcome was the CPR quality index calculated as the proportion of chest compressions with appropriate depth among total chest compressions.Results: The total number of chest compressions remained stable over time both in the chest compression-only and the conventional CPR groups. The CPR quality index, however, decreased from 86.6 +/- 25.0 to 58.2 +/- 36.9 in the chest compression-only CPR group from 0-20s through 61-80 s. The reduction was greater than in the conventional CPR group (85.9 +/- 25.5 to 74.3 +/- 34.0). The difference in the CPR quality index reached statistical significance (p = 0.003) at 61-80s period.Conclusions: Chest compressions with appropriate depth decreased more rapidly during chest compression-only CPR than conventional CPR. We recommend that CPR providers change their roles every 1 min to maintain the quality of chest compressions during chest compression-only CPR. (UMIN-CTR C0000000321) (C) 2010 Elsevier Ireland Ltd.
