Abstract

Objective: Following the 2020 cardiopulmonary resuscitation (CPR) guidelines, this study compared participant's fatigue with the quality of manual chest compressions performed in the head-up CPR (HUP-CPR) and supine CPR (SUP-CPR) positions for two minutes on a manikin.

Methods: Both HUP-CPR and SUP-CPR were performed in a randomized order determined by a lottery-style draw. Manual chest compressions were then performed continuously on a realistic manikin for two minutes in each position, with a 30-minute break between each condition. Data were collected on heart rate, blood pressure, and Borg rating of perceived exertion (RPE) scale scores from the participants before and after the compressions.

Results: Mean chest compression depth (MCCD), mean chest compression rate (MCCR), accurate chest compression depth ratio (ACCDR), and correct hand position ratio were significantly lower in the HUP group than that in the SUP group. However, there were no significant differences in accurate chest compression rate ratio (ACCRR), correct recoil ratio, or mean arterial pressure (MAP) before and after chest compressions between the two groups. Changes in heart rate and RPE scores were greater in the HUP group.

Conclusion: High-quality manual chest compressions can still be performed when the CPR manikin is placed in the HUP position. However, the quality of chest compressions in the HUP position was poorer than those in the SUP position, and rescuer fatigue was increased.

不同心肺复苏体位下人工胸外按压质量及施救者疲劳评价。

目的：根据2020年心肺复苏（CPR）指南，本研究比较了参与者的疲劳与在人体模型上平视CPR （HUP-CPR）和仰卧CPR （SUP-CPR）姿势下进行两分钟的手动胸部按压的质量。方法：HUP-CPR和SUP-CPR均按抽签方式随机顺序进行。然后在一个真实的人体模型上连续进行手动胸外按压，每次按压2分钟，每次按压之间休息30分钟。在按压前后收集参与者的心率、血压和Borg感知运动评分（RPE）量表得分。结果：HUP组患者平均胸压深度（MCCD）、平均胸压率（MCCR）、准确胸压深度比（ACCDR）、正确手位比均显著低于SUP组。但两组在胸按压前后的准确胸压率比（ACCRR）、正确后坐力比、平均动脉压（MAP）均无显著差异。HUP组的心率和RPE评分变化更大。结论：人工心肺复苏模型处于HUP体位时，仍可进行高质量的手工胸外按压。然而，HUP体位的胸外按压质量较SUP体位差，且施救者疲劳加重。
