A trained lay rescuer is the most important determinant of survival from sudden cardiac arrest. Augmented Reality (AR) device may represent a powerful instrument for CPR assistance and self-training especially during the COVID-19 pandemic.
A prospective, parallel, 1:1 pilot randomized clinical trial was designed. An AR CPR app was developed and 28 participants were randomly allocated into AR-assisted group and instructor-assisted group. Acceptability, usability, and mean per minute/per cycle chest compression depth, rate and accuracy were measured.
The mean scores for acceptability and usability were all rated good in each group. Comparing real-time AR-assisted CPR to instructor-assisted CPR, the mean difference of compression depth was 0.18 (95% CI: -0.18-0.53) cm and rate was -1.58 (95% CI: -6.11-2.95) min-1. Comparing AR self-training to instructor training, the AR group was not significantly different between two groups regarding both compression depth, rate and accuracy ( > .05).
We found that the AR CPR app was an acceptable and usable tool both in real-time-assisted CPR and self-training CPR.
经过培训的非专业救援人员是心脏骤停患者生存的最重要决定因素。增强现实（AR）设备可能是心肺复苏（CPR）辅助和自我训练的有力工具，尤其是在新冠疫情期间。
设计了一项前瞻性、平行、1:1的试点随机临床试验。开发了一款AR心肺复苏应用程序，28名参与者被随机分配到AR辅助组和指导员辅助组。测量了可接受性、可用性以及每分钟/每个周期的胸部按压深度、速率和准确性。
每组的可接受性和可用性平均得分均被评为良好。将实时AR辅助心肺复苏与指导员辅助心肺复苏进行比较，按压深度的平均差异为0.18（95%CI：-0.18-0.53）厘米，速率为-1.58（95%CI：-6.11-2.95）次/分钟。将AR自我训练与指导员训练进行比较，AR组在按压深度、速率和准确性方面两组之间无显著差异（P>0.05）。
我们发现，AR心肺复苏应用程序在实时辅助心肺复苏和自我训练心肺复苏中都是一种可接受且可用的工具。
