The Use of the Borg Rating of Perceived Exertion Scale in Cardiopulmonary Resuscitation

Abstract Background A cardiopulmonary arrest is a critical event whose survival rate is related to the quality of resuscitation maneuvers combined with the use of technology. It is important to understand the perception of fatigue during this procedure, aiming to improve the effectiveness of compressions to increase the chances of survival. Objectives To apply the Borg rating of perceived exertion scale (Borg scale) to analyze the exertion perceived by nurses during cardiopulmonary resuscitation maneuvers using a feedback device. Methods Experimental study with a randomized distribution of nurses in a teaching hospital. Perceived exertion during simulated cardiopulmonary resuscitation with/without a feedback device was assessed using the Borg scale. The statistical significance level of 5% was adopted. Results 69 nurses working in critical and non-critical adult care units were included. Perceived exertion and heart rate were lower in the intervention group (p<0.001), influenced by the feedback device, with no significant difference between critical and non-critical units. Conclusions The Borg scale proved to be adequate for the proposed objectives. The feedback device contributed to lower exertion and heart rate reduction during resuscitation maneuvers. The low cost and ease of application favor its use during training and real-time resuscitation attempts to assess performance using a feedback device to reduce exertion and perception of fatigue. It allows reflection on the intervening factors and resources that can influence the quality of resuscitation attempts and the chances of survival.

### 摘要
#### 背景
心搏骤停（cardiopulmonary arrest）是一类危急重症事件，其存活率与复苏操作质量及技术应用水平密切相关。明晰该操作过程中的疲劳感知情况，对优化胸外按压效果、提升患者生存概率具有重要意义。

#### 研究目标
本研究旨在应用伯格自觉劳累评分量表（Borg rating of perceived exertion scale，Borg scale），分析护士在使用反馈设备实施心肺复苏（cardiopulmonary resuscitation）操作时的自觉疲劳程度。

#### 研究方法
本研究为实验性研究，在某教学医院内开展，纳入的护士采用随机分组方式。通过伯格量表评估模拟心肺复苏操作中，使用与未使用反馈设备时的自觉疲劳程度。本研究设定5%为统计学显著性检验水准。

#### 研究结果
本研究共纳入69名来自成人重症监护病房及非重症监护病房的护士。干预组（使用反馈设备组）的自觉疲劳评分与心率均显著更低（p<0.001），该效应由反馈设备介导，且重症与非重症病房护士的相关指标无显著差异。

#### 研究结论
伯格量表可有效适配本研究的预设目标。反馈设备可降低心肺复苏操作中的疲劳感知与心率水平。该设备成本低廉、操作便捷，适合在培训及实时复苏场景中应用，通过反馈机制优化操作表现、减轻操作者疲劳感知。本研究结果可辅助反思影响复苏操作质量及患者生存概率的干预因素与相关资源。
