Abstract：
UNASSIGNED: 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.
UNASSIGNED: This study evaluated a novel smartwatch-based CPR feedback device in enhancing chest compression quality among health care professionals and lay rescuers.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

摘要：
■心肺复苏(CPR)质量显著影响患者在心脏骤停期间的预后。随着医疗保健技术的进步，基于智能手表的CPR反馈设备已经成为增强CPR交付的潜在工具。
■这项研究评估了一种新颖的基于智能手表的CPR反馈设备，可提高医疗保健专业人员和救援人员的胸部按压质量。
■单中心，开放标签，我们对30名受试者进行了随机交叉研究,根据救助者类别分为3组.将中继响应BLS智能手表应用与基于除颤器的反馈设备（ZollOneStepCPR垫）进行了比较。在介绍了这项技术之后，受试者在3个模块中进行胸部按压：基线无辅助，在基于智能手表的反馈设备的帮助下，并由基于除颤器的反馈装置辅助。成果措施包括有效性、可学习性,和可用性。
■在所有组中，基于智能手表的设备显着提高了平均压缩深度有效性（68.4％vs29.7％；P<0.05）和平均率有效性（87.5％vs30.1％；P<0.05），与无辅助按压相比。基于智能手表的设备显着降低了压缩变异性（变异系数：14.9％对26.6％），表明性能更一致。20名专业救援人员中有15名使用基于智能手表的设备在平均2.6秒内实现了有效的按压。可用性问卷显示，基于智能手表的设备比基于除颤器的设备更受欢迎。
■基于智能手表的设备通过将按压保持在推荐范围内并减少性能可变性来增强CPR传递的质量。它的用户友好性和快速可学习性表明，在专业和外行救援人员场景中都有广泛采用的潜力。积极促进心肺复苏培训和现实生活中的应急反应。
