To investigate the feasibility of mobile videocall guidance to facilitate AED use by laypersons. . A total of 90 laypersons were randomized into three groups: the mobile video call-guided, voice call-guided, and non-guided groups. Participants were exposed to simulated cardiac arrest to use an AED, and guided by video calls, voice calls, or were not guided. We recorded the simulation experiments as a videoclip, and other researchers who were blinded to the simulation assessed the performance according to the prespecified checklist after simulations. . We compared the performance score and time intervals from AED arrival to defibrillation among the three groups and analyzed the common errors.
There was no significant difference among the three groups in terms of baseline characteristics. Performance scores in the checklist for using AED were higher in the mobile video call-guided group, especially in the category of "Power on AED" and "Correctly attaches pads" than in the other groups. However, the time interval to defibrillation was significantly longer in the mobile video call-guided group.
Mobile video call guidance might be an alternative method to facilitate AED use by laypersons. Therefore, further well-designed research is needed to evaluate the feasibility of this approach in OHCA.
研究移动视频通话指导对非专业人员使用 AED 的可行性。方法：共招募 90 名非专业人员，随机分为三组：移动视频通话指导组、语音通话指导组和无指导组。参与者接受模拟心脏骤停使用 AED 的培训，分别接受视频通话、语音通话或无指导。我们将模拟实验记录为视频片段，然后让其他对模拟情况不知情的研究人员根据预定的检查表对实验后进行评估。结果：三组在基线特征方面没有显著差异。使用 AED 的检查表中的性能评分在移动视频通话指导组中较高，尤其是在“打开 AED”和“正确粘贴电极片”类别中高于其他组。然而，移动视频通话指导组的除颤时间间隔明显较长。结论：移动视频通话指导可能是一种辅助非专业人员使用 AED 的替代方法。因此，需要进一步进行精心设计的研究来评估在 OHCA 中使用这种方法的可行性。
