Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–50 who have not received CPR training in the past 12 months, who are not healthcare professionals, and who can safely use mixed-reality equipment.

Probably not a fit

Healthcare professionals, people over age 50, anyone with recent CPR training, or those who cannot tolerate MR equipment (e.g., motion sickness) are unlikely to be eligible or to benefit.

What this trial studies

This is a cluster-randomized, stratified non-inferiority trial comparing the HEROS 4.0 mixed-reality (MR) CPR training system with conventional video- and instructor-led CPR instruction. A total of 120 adults aged 18–50 who have not had CPR training in the prior 12 months will be randomized 1:1 by cluster to MR or standard training. The primary outcome is CPR performance quality, with additional evaluation of feasibility, immersion, scalability, and educational effectiveness. Healthcare professionals and individuals unable to safely tolerate MR equipment (for example, due to motion sickness) are excluded.

Why it matters

Potential benefit: If successful, MR-based HEROS 4.0 training could expand access to high-quality, immersive CPR instruction that matches traditional training while being more scalable.

How similar studies have gone: Previous VR and mixed-reality simulation studies have generally shown comparable improvements in CPR skills to traditional methods, though HEROS 4.0 is a newer platform with limited direct evidence.
