The aim of the study was to explore feasibility of basic life support (BLS) guided through smart glasses (SGs) when assisting fishermen bystanders. Twelve participants assisted a simulated out-of-hospital cardiac arrest on a fishing boat assisted by the dispatcher through the SGs. The SGs were connected to make video calls. Feasibility was assessed whether or not they needed help from the dispatcher. BLS-AED steps, time to first shock/compression, and CPR's quality (hands-only) during 2 consecutive minutes (1st minute without dispatcher feedback, 2nd with dispatcher feedback) were analyzed. Reliability was analyzed by comparing the assessment of variables performed by the dispatcher through SGs with those registered by an on-scene instructor. Assistance through SGs was needed in 72% of the BLS steps, which enabled all participants to perform the ABC approach and use AED correctly. Feasibility was proven that dispatcher's feedback through SGs helped to improve bystanders' performance, as after dispatcher gave feedback via SGs, only 3% of skills were incorrect. Comparison of on-scene instructor vs. SGs assessment by dispatcher differ in 8% of the analyzed skills: greatest difference in the "incorrect hand position during CPR" (on-scene: 33% vs. dispatcher: 0%). When comparing the 1st minute with 2nd minute, there were only significant differences in the percentage of compressions with correct depth (1st:48 ± 42%, 2nd:70 ± 31, p = 0.02). Using SGs in aquatic settings is feasible and improves BLS. CPR quality markers were similar with and without SG. These devices have great potential for communication between dispatchers and laypersons but need more development to be used in real emergencies.
本研究旨在探讨智能眼镜（SGs）辅助渔民旁观者进行基本生命支持（BLS）的可行性。十二名参与者在调度员的协助下，通过 SGs 协助在渔船上进行模拟院外心脏骤停。SGs 相连以进行视频通话。评估了他们是否需要调度员的帮助。分析了 BLS-AED 步骤、第一次电击/按压的时间以及连续两分钟（第一分钟无调度员反馈，第二分钟有调度员反馈）的 CPR 质量（仅手按）。通过比较调度员通过 SGs 进行的变量评估与现场指导员记录的变量评估，分析了可靠性。通过 SGs 提供的帮助在 72%的 BLS 步骤中是必要的，这使得所有参与者都能够正确执行 ABC 方法并使用 AED。通过 SGs 从调度员处获得反馈有助于提高旁观者的表现，这是因为在调度员通过 SGs 提供反馈后，只有 3%的技能是不正确的。现场指导员与调度员通过 SGs 评估之间的比较在 8%的分析技能上存在差异：最大差异在于“CPR 时手的不正确位置”（现场：33%比调度员：0%）。在比较第一分钟和第二分钟时，仅在正确按压深度的百分比上存在显著差异（第一分钟：48±42%，第二分钟：70±31%，p=0.02）。在水上环境中使用 SGs 是可行的，可以提高 BLS。CPR 质量指标在使用和不使用 SGs 时相似。这些设备在调度员和非专业人员之间的通信方面具有巨大潜力，但需要进一步开发才能在实际紧急情况下使用。
