Video-assisted cardiopulmonary resuscitation (V-CPR) describes an advanced telephone-assisted CPR (T-CPR), in which emergency medical service (EMS) dispatchers view a live video steam of the resuscitation. Dispatchers ' general attitudes toward and self-assessment in V-CPR have not been previously investigated.
We conducted this quantitative analysis along with a pilot study on V-CPR. After conducting V-CPR with laypersons in a simulation, EMS dispatchers were given questionnaires with 21 items concerning their personal attitude toward V-CPR and their self-assessment in providing instructions. The actual CPR performance achieved was recorded and compared to the dispatchers' self-assessments.
Dispatchers completed 49 questionnaires, and the data is presented descriptively. Over 80% strongly agreed that V-CPR was helpful in guiding and that their feedback improved CPR quality. Fifty-one percent agreed that video images supported them in making a diagnosis, while 44.9% disagreed. A vast majority (80-90% each) strongly agreed that V-CPR helped them recognize CPR issues such as compression point, compression rate, and deterioration. In contrast, data for improved compression depth and release were weaker. Thirty percent found V-CPR to be more stressful or exhausting than T-CPR. A majority stated they would prefer V-CPR as an addition to T-CPR in the future. There was a huge gap between dispatchers' own view of CPR effort and measured CPR quality.
Dispatchers generally embrace V-CPR and praise the abilities it provides. Our results indicate that the use of V-CPR did not automatically result in an overall improvement in guideline-compliant CPR quality.
视频辅助心肺复苏术（V-CPR）描述了一种先进的电话辅助 CPR（T-CPR），其中紧急医疗服务（EMS）调度员可以查看复苏的实时视频流。调度员对 V-CPR 的一般态度和自我评估以前没有被调查过。
我们对 V-CPR 进行了这项定量分析和试点研究。在模拟中与非专业人员进行 V-CPR 后，EMS 调度员收到了 21 个关于他们对 V-CPR 的个人态度和提供指导的自我评估的问卷。记录实际的 CPR 表现，并将其与调度员的自我评估进行比较。
调度员完成了 49 份问卷，数据以描述性方式呈现。超过 80%的人强烈认为 V-CPR 有助于指导，他们的反馈提高了 CPR 质量。51%的人同意视频图像支持他们做出诊断，而 44.9%的人不同意。绝大多数（80-90%）强烈认为 V-CPR 有助于他们识别 CPR 问题，如按压点、按压率和恶化。相比之下，关于提高压缩深度和释放的数据则较弱。30%的人认为 V-CPR 比 T-CPR 更紧张或更累。大多数人表示，他们将来更愿意将 V-CPR 作为 T-CPR 的补充。调度员对 CPR 努力的看法与测量的 CPR 质量之间存在巨大差距。
调度员普遍接受 V-CPR，并赞扬它提供的能力。我们的结果表明，使用 V-CPR 并不一定会自动导致符合指南的 CPR 质量的整体提高。
