Treffer: Immersive Virtual Simulation Boosts CPR Competency in Vocational Nursing Students: A Randomized Controlled Trial

This study investigates the effectiveness of Virtual Simulation Systems (VSS) in improving cardiopulmonary resuscitation (CPR) training outcomes for vocational nursing students through a cluster randomized controlled trial. A total of 100 second-year nursing students from Sichuan Health Rehabilitation Vocational College were divided into an experimental group, which received VSS-based training incorporating virtual reality, real-time feedback, and interactive scenarios, and a control group following traditional manikin-based methods. After a four-week intervention, the experimental group exhibited significantly higher scores in theoretical knowledge (mean 88.68 versus 75.24) and practical skills (mean 85.10 versus 81.52), with statistical significance confirmed. Participants in the VSS group also reported greater satisfaction and engagement, emphasizing the system's ability to replicate clinical realism and reduce performance anxiety. These results demonstrate that VSS addresses critical gaps in conventional CPR education by enhancing competency through immersive, adaptive learning. The findings support the integration of technology-driven training in vocational nursing programs, particularly in resource-limited settings. Future research should focus on long-term skill retention and scalable implementation strategies to optimize the educational impact of virtual simulations.
