A total of 22 resident-grade physicians (15 males [68.2%]; median [range] age, 28 [25-34] years) were prospectively recruited. All participants had prior experience or qualifications in advanced life support skills and resuscitation. There were 2 participants (9.1%) with 1 year of clinical practice since their primary medical qualification, 14 participants (63.6%) with at least 2 years, and 6 participants (27.3%) with 3 years or more. There were 2 participants (9.1%) who had previously used the MR device analyzed in this study, 18 participants (81.8%) who had heard of the technology but not previously used a device, and 2 participants (9.1%) had never heard of or used the technology. All participants were able to safely use the device without impediment, and there were no technical failures of wireless connectivity or data recording during the trial.
