Abstract

BACKGROUND

Using a mobile virtual reality (VR) platform to heighten realism for cardiopulmonary resuscitation (CPR) training has the potential to improve bystander response.

OBJECTIVES

We examined whether using a VR mobile application (mApp) for CPR training would improve bystander response compared with a standard mApp CPR training.

METHODS

We randomized lay bystanders to either our intervention arm (VR mApp) or our control arm (mApp). During a post-intervention skills test, we collected bystander response data (call 911, perform CPR, ask for an automated external defibrillator (AED)), along with CPR quality (chest compression (CC) rate and depth). Wilcox rank sum was used to analyze CC rate and CC depth as they were not normally distributed; Pearson's Chi-square was used to analyze Chain of Survival variables.

RESULTS

Between 3/2018 and 9/2018, 105 subjects were enrolled: 52 VR mApp and 53 mApp. Mean age was 46 ± 16 years, 34% were female, 59% were Black, and 17% were currently CPR trained (≤2 years). Bystander response was significantly higher in the VR mApp arm: called 911 (82% vs 58%, p = 0.007) and asked for an AED (57% vs 28%, p = 0.003). However there was no difference in CPR performed (98% vs 98%, p = NS) and the application of the AED (90% vs 93%, p = NS). When comparing the VR mApp to the mApp, mean CC rate was 104 ± 42 cpm vs 112 ± 30 cpm (p = NS), and mean CC depth was 38 ± 15 mm vs 44 ± 13 mm (p = 0.05).

CONCLUSION

The use of the VR mApp significantly increased the likelihood of calling 911 and asking for an AED, however, CC depth was decreased.

摘要

背景

使用移动虚拟现实（VR）平台来提高心肺复苏（CPR）培训的真实感，有可能改善旁观者的反应。

目的

我们研究了使用 VR 移动应用程序（mApp）进行 CPR 培训是否比标准 mApp CPR 培训更能改善旁观者的反应。

方法

我们将非专业旁观者随机分配到干预组（VR mApp）或对照组（mApp）。在干预后的技能测试中，我们收集了旁观者的反应数据（拨打 911、进行 CPR、请求自动体外除颤器（AED）），以及 CPR 质量（按压频率和深度）。由于 CC 频率和 CC 深度未呈正态分布，因此使用 Wilcox 秩和检验进行分析；使用 Pearson 卡方检验分析生存链变量。

结果

2018 年 3 月至 2018 年 9 月期间，共纳入 105 名受试者：VR mApp 组 52 名，mApp 组 53 名。平均年龄为 46±16 岁，34%为女性，59%为黑人，17%的人目前接受过（≤2 年）CPR 培训。VR mApp 组的旁观者反应明显更高：拨打 911（82%比 58%，p=0.007）和请求 AED（57%比 28%，p=0.003）。然而，进行的 CPR（98%比 98%，p=NS）和 AED 的应用（90%比 93%，p=NS）没有差异。当将 VR mApp 与 mApp 进行比较时，平均 CC 频率为 104±42 cpm 比 112±30 cpm（p=NS），平均 CC 深度为 38±15 mm 比 44±13 mm（p=0.05）。
