Video-assisted cardiopulmonary resuscitation (V-CPR) can improve the quality of bystander-performed CPR; however, its applicability has not been explored in situations where the lay responder is alone with the victim. This pilot study aimed to assess the feasibility of V-CPR in such scenarios. A randomized controlled crossover simulation study was conducted with 10 lay responders in two settings: a residential living room and a yard. Participants used available household objects to position a smartphone for a live video call with a dispatcher. The study evaluated (1) camera placement and perspective, (2) camera placement time, and (3) video quality and CPR assessability, based on assessors evaluations. No participant failed to establish a usable camera view. The average placement time was 23.4 s indoors and 34.0 s outdoors (p = 0.075). Based on five assessors, hand position and compression rate were highly assessable (86% and 84%), while compression depth was correctly assessed in only 32%. Although V-CPR quality varied between environments, the method proved feasible even when responders acted alone. Further studies are needed to compare the results with commercial V-CPR, optimize camera positioning, reduce delays, and evaluate outcomes using standardized dispatcher protocols. This study was retrospectively registered at https://clinicaltrials.gov/ ClinicalTrials.gov (NCT06794398, 01/27/2025).
视频辅助心肺复苏（V-CPR）可提高旁观者实施心肺复苏的质量；然而，在现场急救人员单独与受害者在一起的情况下，其适用性尚未得到探索。这项初步研究旨在评估V-CPR在这种场景中的可行性。在两种场景下对10名现场急救人员进行了一项随机对照交叉模拟研究：住宅客厅和院子。参与者使用现有的家用物品放置智能手机，以便与调度员进行实时视频通话。该研究基于评估者的评估，对（1）摄像头放置和视角、（2）摄像头放置时间以及（3）视频质量和心肺复苏可评估性进行了评估。没有参与者未能建立可用的摄像头视图。室内平均放置时间为23.4秒，室外为34.0秒（p = 0.075）。基于五名评估者的评估，手部位置和按压频率的可评估性很高（分别为86%和84%），而按压深度的正确评估率仅为32%。尽管V-CPR质量在不同环境中有所不同，但即使急救人员单独行动，该方法也证明是可行的。需要进一步研究将结果与商用V-CPR进行比较，优化摄像头定位，减少延迟，并使用标准化调度员协议评估结果。本研究已在https://clinicaltrials.gov/ClinicalTrials.gov（NCT06794398，2025年1月27日）进行回顾性注册。
