: Appropriate clinical training for emergencies is a key factor in the quality of healthcare. Advances in technology facilitate the creation of new forms of training, fostering student interaction and engagement. In this respect, augmented and virtual reality approaches in healthcare training are generating great interest. : to evaluate the effectiveness of virtual and augmented reality in emergency healthcare training. : A randomized controlled trial was conducted with two intervention groups. Intervention group No. 1 ( = 30) received in-class instruction followed by practice with a cardiopulmonary resuscitation (CPR) manikin and using virtual reality with the Meta Quest model (using the VR applications Heart, Lung, and School of CPR). Intervention group No. 2 ( = 31) received the same in-class training but followed by an augmented reality session. In this intervention, the Heart and Lung AR applications were used on an iPhone 15 ProMax. The control group ( = 32) only received in-class instruction and practice with the CPR manikin. : The virtual reality and augmented reality interventions improved learning effectiveness and user satisfaction. These results were statistically significant ( < 0.05) for knowledge post-intervention between groups, VR being the highest. However, the results were not significant for satisfaction. : VR procedures can be effective for increasing learning effectiveness in emergency training.
