This systematic review evaluates the effectiveness of augmented reality (AR) and virtual reality (VR) in resuscitation training compared to other instructional methods. The review, conducted by the International Liaison Committee on Resuscitation (ILCOR) Education Implementation Team Task Force, included 19 studies published between 2014 and 2023. AR was used in 4 studies to provide real-time feedback during CPR, showing improved performance compared to no feedback but not significantly different from other feedback sources. VR was explored in 15 studies, with most assessing CPR skills, where VR did not show a consistent advantage over other interventions. The review found that AR can enhance CPR performance with real-time feedback, while VR's impact on knowledge acquisition and retention is mixed. The overall evidence is rated as very low due to heterogeneity and risk of bias. The review concludes that while AR and VR can support resuscitation training, current evidence does not clearly demonstrate a consistent benefit over other training methods. Future research should explore the synergistic effects of immersive technology with other educational strategies and assess long-term knowledge and skill retention.This systematic review evaluates the effectiveness of augmented reality (AR) and virtual reality (VR) in resuscitation training compared to other instructional methods.
