Widespread knowledge of cardiopulmonary resuscitation (CPR) is critical to improving survival in sudden cardiac death. We analyzed YouTube, an Internet video-site which is a growing source of healthcare information for source, content and quality of information about CPR.
YouTube was queried using keywords "CPR", "Cardiopulmonary resuscitation", "BLS" and "Basic life support". Videos in English demonstrating CPR technique were included. Videos were classified by upload source, content, structure of course, subject for CPR demonstration, etc. Videos were scored for 'accuracy of demonstration' of CPR steps on a scale of 0-8 and for 'viewability'.
Of 800 videos screened 52 met the inclusion criteria with mean duration of 233 (±145)s and view count 37 (±77) per day. 48% (n = 25) videos were by individuals with unspecified credentials. No differences were noted in view count/day, 'accuracy of demonstration' and 'viewability' among videos based on source. No information was provided about scene safety assessment in 65% (n = 34) videos. Only 69% (n = 31/45) videos demonstrated the correct compression-ventilation ratio while 63.5% (n = 33), 34.6% (n = 18) and 40.4% (n = 21) gave information on location, rate and depth of chest compressions respectively. 19% (n = 10) videos incorrectly recommended checking for pulse.
Videos judged the best source for CPR information were not the ones most viewed. Information on this platform is unregulated, hence content by trusted sources should be posted to provide accurate and easily accessible information about CPR. YouTube may have a potential role in video-assisted learning of CPR and as source of information for CPR in emergencies.
广泛了解心肺复苏术（CPR）对于提高心源性猝死患者的存活率至关重要。我们分析了 YouTube，这是一个互联网视频网站，也是医疗保健信息的重要来源，以了解有关 CPR 的信息来源、内容和质量。
使用“CPR”、“心肺复苏术”、“BLS”和“基础生命支持”等关键词在 YouTube 上进行查询。纳入演示 CPR 技术的英语视频。根据上传来源、内容、课程结构、CPR 演示主题等对视频进行分类。根据 CPR 步骤演示的准确性（0-8 分）和可观看性对视频进行评分。
在筛选的 800 个视频中，有 52 个符合纳入标准，平均时长为 233（±145）秒，每日观看次数为 37（±77）次。48%（n=25）的视频来自未指定资质的个人。基于来源，每日观看次数、“演示准确性”和“可观看性”在视频之间没有差异。65%（n=34）的视频未提供有关现场安全评估的信息。只有 69%（n=31/45）的视频演示了正确的按压通气比，而 63.5%（n=33）、34.6%（n=18）和 40.4%（n=21）分别提供了有关位置、频率和深度的信息。19%（n=10）的视频错误地建议检查脉搏。
被评为 CPR 信息最佳来源的视频并非最受欢迎的视频。该平台上的信息不受监管，因此应发布来自可信赖来源的信息，以提供有关 CPR 的准确且易于访问的信息。YouTube 可能在视频辅助 CPR 学习以及在紧急情况下作为 CPR 信息来源方面具有潜在作用。
