Aprendizaje combinado frente a realidad virtual y métodos tradicionales en la formación en reanimación cardiopulmonar: un ensayo aleatorizado en estudiantes universitarios

OBJECTIVE: Out-of-hospital cardiac arrest is the leading cause of sudden death. Basic Life Support (BLS) training is an essential competency in Nursing. Active learning methodologies such as blended learning may improve educational outcomes. DESIGN: A randomized controlled trial with four parallel groups (n=160). PARTICIPANTS: was conducted among first-year undergraduate nursing students. Site: At a university in the Region of Murcia, Spain. INTERVENTIONS: Four methodologies were compared: traditional training, virtual reality (VR), blended learning, and a control group with no intervention. Practical competence was assessed using an 8-item checklist covering key steps in the chain of survival. Technical parameters were measured using Laerdal QCPR® manikins, including percentage of high-quality CPR, compression depth, rate, and full chest recoil. ANOVA, chi-square tests, and correlation models were applied (p
