CPR training at mass gathering events is an important part of health initiatives to improve cardiac arrest survival. However, it is unclear whether training lay bystanders using an ultra-brief video at a mass gathering event improves CPR quality and responsiveness.
To determine if showing a chest-compression only (CCO) Ultra-Brief Video (UBV) at a mass gathering event is effective in teaching lay bystanders CCO-CPR.
Prospective control trial in adults (age >18) who attended either a women's University of Arizona or a men's Phoenix Suns basketball game. Participants were evaluated using a standardized cardiac arrest scenario with Laerdal Skillreporter™ mannequins. CPR responsiveness (calling 911, time to calling 911, starting compressions within two minutes) and quality (compression rate, depth, hands-off time) were assessed for participants and data collected at Baseline and Post-intervention. Different participants were tested before and after the exposure of the UBV. Data were analyzed via the intention to treat principle using logistic regression for binary outcomes and median regression for continuous outcomes, controlling for clustering by venue.
A total of 96 people were consented (Baseline=45; Post intervention=51). CPR responsiveness post intervention improved with faster time to calling 911 (s) and time to starting compressions (sec). Likewise, CPR quality improved with deeper compressions and improved hands-off time.
Showing a UBV at a mass gathering sporting event is associated with improved CPR responsiveness and performance for lay bystanders. This data provides further support for the use of mass media interventions.
在大型集会活动中进行心肺复苏术 (CPR) 培训是提高心脏骤停存活率的健康倡议的重要组成部分。然而，目前尚不清楚在大型集会活动中培训非专业旁观者使用超简短视频是否能提高 CPR 的质量和反应能力。
确定在大型集会活动中展示仅胸部按压（CCO）超简短视频（UBV）是否能有效教授非专业旁观者 CCO-CPR。
在参加亚利桑那大学女子或菲尼克斯太阳队男子篮球比赛的成年人（年龄>18 岁）中进行前瞻性对照试验。使用莱德尔 Skillreporter™模拟人评估参与者的标准化心脏骤停情况。CPR 的反应性（拨打 911、拨打 911 的时间、在两分钟内开始按压）和质量（按压频率、深度、手离开时间）在基线和干预后进行评估。不同的参与者在暴露于 UBV 之前和之后进行了测试。通过使用逻辑回归进行二元结果和中位数回归进行连续结果的意向治疗原则分析数据，控制场地聚类。
共有 96 人同意参与（基线=45；干预后=51）。干预后，CPR 的反应性得到改善，表现为拨打 911 的时间更快（s）和开始按压的时间更短（sec）。同样，CPR 质量也得到了改善，表现为按压更深，手离开时间更长。
在大型集会体育赛事中展示 UBV 与提高非专业旁观者的 CPR 反应性和表现相关。这些数据进一步支持使用大众媒体干预。
