Comparing Mixed Reality and Standard Instructor-Led CPR Training for Adults Aged 18 to 50 to Improve CPR Skills and Knowledge

What this Trial Is About

Researchers are evaluating the feasibility, effectiveness, and educational value of HEROS 4.0, a mixed-reality MR cardiopulmonary resuscitation CPR training system compared to traditional instructor-led CPR training. This cluster-randomized, non-inferiority trial aims to determine if MR-based training provides CPR performance quality comparable to standard video and instructor methods. The study involves adults aged 18 to 50 who have not had CPR training in the past year. Participants are randomly assigned to one of two groups. The HEROS 4.0 group completes a two-stage program first, watching a 40-minute instructional video at home, then undergoing 20 minutes of MR-based CPR training in a specialized booth. The conventional group receives 60 minutes of standard CPR education with videos and in-person instruction. Both groups receive training covering cardiac arrest recognition, emergency response, chest compressions, and defibrillator use. After training, all participants perform a simulated cardiac arrest scenario assessed by a CPR quality-measurement manikin. The main outcome is chest compression fraction measured immediately and again after six months to evaluate skill retention. Secondary outcomes include compression depth, rate, adequate compression proportions, overall life support performance, participant confidence, and system usability. Questionnaires and objective measures are used to track performance over time, with safety monitored throughout the study period.
