Optimal depth (50-60mm) and rate (100-120min(-1)) of chest compressions (CC) is the prerequisite of effective cardiopulmonary resuscitation (CPR). However, insufficient CC during CPR are common even among health care professionals. We sought to evaluate if CC are more effective with the use of a novel feedback device compared to standard CC. Primary endpoints were absolute percentage of correct CC of all CC (correct rate and correct depth, classified as "optimal" CC), and the percentage of CC in target rate and percentage of CC in target depth.
63 healthcare professionals performed CC on a manikin with the use of a novel feedback device. The device provides audio-visual information about compression depth and rate. Each participant performed two minutes of CC with and without feedback. Participants were randomized into two groups that performed either CC with feedback first, followed by a trial without feedback, or vice versa. All participants answered a short questionnaire on self-estimation of CC performance.
The absolute percentage of optimal compressions of all compressions has increased from 27.9±28.8% to 47.6±33.5% (p<0.001) with use of the device. Furthermore, a significant increase of the percentage of CC in target depth (35.9±30.6% without vs. 54.8±33.5% with the device, p=0.003) and in target rate (70.5±37.7% without vs. 82.7±27.8 with the device, p=0.039) were observed.
This novel feedback device significantly improved the quality of CC in health care professionals.
胸外按压（CC）的最佳深度（50 - 60毫米）和速率（100 - 120次/分钟）是有效的心肺复苏（CPR）的前提条件。然而，即使在医护人员中，心肺复苏期间胸外按压不足也很常见。我们试图评估与标准胸外按压相比，使用新型反馈设备进行胸外按压是否更有效。主要终点是所有胸外按压中正确胸外按压的绝对百分比（正确率和正确深度，分类为“最佳”胸外按压），以及目标速率下胸外按压的百分比和目标深度下胸外按压的百分比。
63名医护人员使用新型反馈设备在模拟人上进行胸外按压。该设备提供有关按压深度和速率的视听信息。每位参与者进行有反馈和无反馈的两分钟胸外按压。参与者被随机分为两组，一组先进行有反馈的胸外按压，然后进行无反馈的试验，另一组则相反。所有参与者回答了一份关于胸外按压表现自我评估的简短问卷。
使用该设备后，所有按压中最佳按压的绝对百分比从27.9±28.8%增加到47.6±33.5%（p<0.001）。此外，观察到目标深度下胸外按压的百分比（无设备时为35.9±30.6%，有设备时为54.8±33.5%，p = 0.003）和目标速率下胸外按压的百分比（无设备时为70.5±37.7%，有设备时为82.7±27.8%，p = 0.039）有显著增加。
这种新型反馈设备显著提高了医护人员胸外按压的质量。
