Immediate initiation of cardiopulmonary resuscitation significantly increases the chances of survival after a cardiac arrest. Virtual reality devices allow the integration of features of real patients into training to facilitate interaction and feedback, thus improving performance. However, its use as a training tool remains underexplored. The aims of this study were to undertake initial testing of a virtual reality basic life support prototype and to explore users' views and experiences.
We recruited 23 adult staff members working at a Central London University in England and exposed them to a 5-minute virtual reality experience. Each participant completed a prequestionnaire and postquestionnaire and took part in a focus group discussion. Quantitative data were descriptively analyzed, whereas qualitative data underwent thematic analysis.
Regardless of prior experience of using virtual reality and/or performing basic life support, most participants scored more than 90% for chest compressions and reported an increase in confidence and competence after the experience. Focus group discussions identified the following 4 key themes: experience and expectations; performance and feedback; interaction and immersion; and potential.
Our study suggests that virtual reality is an enjoyable method by which to teach basic life support. Although concerns over the accuracy of the tracking system and the small sample size weaken our conclusions regarding its ability to assess performance, our exploratory data are of value to educators, researchers, and policy makers. Future work needs to address our study limitations, consider how virtual reality fits into the broader context of training, and attend to accreditation and resource issues.
立即开始心肺复苏术可显著提高心脏骤停后患者的生存机会。虚拟现实设备允许将真实患者的特征整合到培训中，以促进互动和反馈，从而提高表现。然而，其作为一种培训工具的使用仍未得到充分探索。本研究的目的是对虚拟现实基本生命支持原型进行初步测试，并探索用户的观点和经验。
我们招募了 23 名在英格兰伦敦市中心大学工作的成年员工，并让他们体验了 5 分钟的虚拟现实体验。每位参与者都完成了一份预调查问卷和后调查问卷，并参加了焦点小组讨论。定量数据进行了描述性分析，而定性数据则进行了主题分析。
无论参与者是否有使用虚拟现实和/或进行基本生命支持的经验，大多数参与者的胸外按压得分都超过 90%，并报告在体验后信心和能力有所提高。焦点小组讨论确定了以下 4 个关键主题：体验和期望；表现和反馈；互动和沉浸感；以及潜力。
我们的研究表明，虚拟现实是一种有趣的教授基本生命支持的方法。尽管对跟踪系统准确性和样本量小的担忧削弱了我们对其评估表现能力的结论，但我们的探索性数据对教育工作者、研究人员和政策制定者具有价值。未来的工作需要解决我们研究的局限性，考虑虚拟现实如何适应更广泛的培训背景，并关注认证和资源问题。
