Long-Term Effect of Intelligent Virtual Reality First-Aid Training on Cardiopulmonary Resuscitation Skill Proficiency.

Objectives: To explore the long-term effect of intelligent first-aid training based on virtual reality (VR) technology on cardiopulmonary resuscitation (CPR) skill proficiency.

Methods: The convenience sampling method was used to select a total of 100 non-medical volunteers from Nanchang, China, and this cohort was randomized to either the VR training group (VR group) or the traditional simulation scenario training group (traditional group). Relevant data were collected for comparative analysis. Participants were evaluated by measuring mean chest compression depth, chest compression pauses time, the proportion of compressions with correct compression depth, mean chest compression rate, and mean ventilation volume.

Results: After initial training, the two groups of participants showed similar results in terms of chest compression depth and chest compression rate. There were significant differences in chest compression pauses time, proportion of compressions with correct compression depth, and ventilation volume ( < 0.001). Long-term follow-up (12 months) after training showed that both groups of participants showed differences in the above indicators ( < 0.001). After training, the VR group had higher pass proportions for mean chest compression rate ( = 0.047) and mean ventilation volume ( = 0.043) than the traditional group. After training, the VR group had higher pass proportion for mean chest compression depth ( < 0.001), mean chest compression rate ( < 0.001), and mean ventilation volume ( < 0.001) than the traditional group.

Conclusions: Training with VR can significantly improve CPR knowledge and skill levels and help learners master and maintain high-quality CPR skills.
