摘要
背景心肺复苏（CPR）的质量对心脏骤停患者的预后有重大影响。随着医疗保健技术的进步，基于智能手表的心肺复苏反馈设备已成为提高心肺复苏实施质量的潜在工具。本研究评估了基于智能手表的新型心肺复苏反馈设备在提高医疗保健专业人员和非专业施救者胸外按压质量方面的作用。Relay Response BLS 智能手表应用与除颤仪反馈设备（Zoll OneStep CPR Pads）进行了比较。在对技术进行介绍后，受试者在 3 个模块中进行胸外按压：基线无辅助、基于智能手表的反馈设备辅助和基于除颤仪的反馈设备辅助。结果在所有组别中，与无辅助按压相比，基于智能手表的设备显著提高了平均按压深度效果（68.4% vs 29.7%; P <.05）和平均按压频率效果（87.5% vs 30.1%; P <.05）。基于智能手表的设备大大降低了按压的变异性（变异系数：14.9% vs 26.6%），表明其性能更加稳定。在 20 名专业救援人员中，有 15 人使用智能手表设备在平均 2.6 秒内实现了有效按压。可用性问卷调查显示，与除颤器设备相比，智能手表设备更受青睐。 结论：智能手表设备可将按压次数控制在推荐范围内，并减少性能变化，从而提高心肺复苏的质量。它的用户友好性和快速可学性表明，它有可能在专业和非专业救援人员的场景中得到广泛应用，为心肺复苏培训和现实生活中的应急响应做出积极贡献。
A smartwatch-based CPR feedback device improves chest compression quality among health care professionals and lay rescuers
Background
Cardiopulmonary resuscitation (CPR) quality significantly impacts patient outcomes during cardiac arrests. With advancements in health care technology, smartwatch-based CPR feedback devices have emerged as potential tools to enhance CPR delivery.
Objective
This study evaluated a novel smartwatch-based CPR feedback device in enhancing chest compression quality among health care professionals and lay rescuers.
Methods
A single-center, open-label, randomized crossover study was conducted with 30 subjects categorized into 3 groups based on rescuer category. The Relay Response BLS smartwatch application was compared to a defibrillator-based feedback device (Zoll OneStep CPR Pads). Following an introduction to the technology, subjects performed chest compressions in 3 modules: baseline unaided, aided by the smartwatch-based feedback device, and aided by the defibrillator-based feedback device. Outcome measures included effectiveness, learnability, and usability.
Results
Across all groups, the smartwatch-based device significantly improved mean compression depth effectiveness (68.4% vs 29.7%; P < .05) and mean rate effectiveness (87.5% vs 30.1%; P < .05), compared to unaided compressions. Compression variability was significantly reduced with the smartwatch-based device (coefficient of variation: 14.9% vs 26.6%), indicating more consistent performance. Fifteen of 20 professional rescuers reached effective compressions using the smartwatch-based device in an average 2.6 seconds. A usability questionnaire revealed strong preference for the smartwatch-based device over the defibrillator-based device.
Conclusion
The smartwatch-based device enhances the quality of CPR delivery by keeping compressions within recommended ranges and reducing performance variability. Its user-friendliness and rapid learnability suggest potential for widespread adoption in both professional and lay rescuer scenarios, contributing positively to CPR training and real-life emergency responses.
