本研究的目的是确定医院提供者的心肺复苏（CPR）知识，以及知识是否会影响模拟心脏骤停期间有效按压的性能。这项横断面研究评估了医学生和艾德人员的心肺复苏术知识和表现与当前的心肺复苏术认证。我们通过问卷调查收集了有关压缩率，手的位置，深度和反冲的数据，以确定知识，然后我们使用60秒的模拟人体模型上的压缩来评估性能。由对受试者知识不知情的评价者对200例入组的数据进行分析。在知识方面，94%的参与者正确识别了速率参数，58%的手放置，74%的深度和94%的反冲。识别有效率≥100的参与者进行按压的频率显著高于识别<100的参与者（μ=117 vs. 94，p<0.001）。识别正确手放置的参与者比识别不正确放置的参与者进行了更多的遵循指南的按压（μ=86% vs. 72%，p<0.01）。根据指南知识，未发现深度或反冲性能存在显著差异。指南的知识是可变的，但是，心肺复苏术知识显着影响某些方面的性能，即速率和手的位置，而深度和反冲力不受影响。无论先前的知识如何，按压深度都很差，并且知识与反冲性能无关。总体表现欠佳，可能需要额外的培训，以确保一致、有效的表现，从而在心肺骤停后获得更好的结局。
The purpose of this study was to determine cardiopulmonary resuscitation (CPR) knowledge of hospital providers and whether knowledge affects performance of effective compressions during a simulated cardiac arrest. This cross-sectional study evaluated the CPR knowledge and performance of medical students and ED personnel with current CPR certification. We collected data regarding compression rate, hand placement, depth, and recoil via a questionnaire to determine knowledge, and then we assessed performance using 60 seconds of compressions on a simulation mannequin. Data from 200 enrollments were analyzed by evaluators blinded to subject knowledge. Regarding knowledge, 94% of participants correctly identified parameters for rate, 58% for hand placement, 74% for depth, and 94% for recoil. Participants identifying an effective rate of ≥100 performed compressions at a significantly higher rate than participants identifying <100 (μ=117 vs. 94, p<0.001). Participants identifying correct hand placement performed significantly more compressions adherent to guidelines than those identifying incorrect placement (μ=86% vs. 72%, p<0.01). No significant differences were found in depth or recoil performance based on knowledge of guidelines. Knowledge of guidelines was variable; however, CPR knowledge significantly impacted certain aspects of performance, namely rate and hand placement, whereas depth and recoil were not affected. Depth of compressions was poor regardless of prior knowledge, and knowledge did not correlate with recoil performance. Overall performance was suboptimal and additional training may be needed to ensure consistent, effective performance and therefore better outcomes after cardiopulmonary arrest.
