The aim of the study was to compare the quality of chest compressions (CCs) carried out with and without the use of the TrueCPR device during simulated cardiopulmonary resuscitations conducted by trainee doctors.
The study was a prospective, randomized, cross-over simulation study. The study involved 65 trainee doctors who were tasked with performing a 2-min cycle of uninterrupted CCs under conditions of a simulated cardiopulmonary resuscitation of adults. CC were carried out in two scenarios: with and without TrueCPR chest compression support. Participants did not have experience in the use of CCs prior to this study.
The depth of compressions in regard to CC techniques were varied by 45 mm (IQR 43-48) for manual CC and 53 mm (IQR 51-55) for the TrueCPR device (p < 0.001). The incidence of CCs with and without TrueCPR was: 112 (IQR 103-113) vs. 129 (IQR 122-135) compressions (p = 0.002). The degree of complete chest relaxation with the TrueCPR device was 95% (IQR 76-99) and without the device, 33% (IQR 29-38) (p < 0.001).
In the simulation study performed, the use of the TrueCPR device resulted in a significant improvement in the quality of CCs in relation to frequency and depth of CCs and correctness of chest relaxation.
本研究旨在比较在模拟心肺复苏过程中，受训医生使用和不使用 TrueCPR 设备进行的胸外按压（CCs）的质量。
本研究为前瞻性、随机、交叉模拟研究。研究纳入 65 名受训医生，要求其在模拟成人心肺复苏的条件下进行 2 分钟不间断 CCs 循环。CCs 在两种情况下进行：使用和不使用 TrueCPR 胸部按压支持。参与者在此项研究之前没有 CCs 使用经验。
CC 技术的按压深度，手动 CC 为 45mm（IQR 43-48），TrueCPR 设备为 53mm（IQR 51-55）（p<0.001）。有和没有使用 TrueCPR 设备的 CC 发生率分别为：112（IQR 103-113）次与 129（IQR 122-135）次（p=0.002）。使用 TrueCPR 设备时，完全胸部放松的程度为 95%（IQR 76-99），而不使用设备时为 33%（IQR 29-38）（p<0.001）。
在进行的模拟研究中，使用 TrueCPR 设备可显著改善 CCs 的质量，提高 CCs 的频率和深度以及胸部放松的正确性。
