Background The COVID-19 pandemic has created challenges and led to the massive closure of in-person CPR trainings globally. We developed a mobile application-based real-time CPR training solution named HEROS-Remote, which combines instructors, learners, training contents, and CPR feedback in just one app. In this study, we investigated the usability, acceptability, and feasibility of the HEROS-Remote CPR training solution among community lay people.

Method From August to November 2021, HEROS Remote pilot study was conducted in Seoul, Korea. During the study period, 164 learners participated in 22 HEROS-Remote sessions. Before the training, CPR training material, including Little Anne QCPR manikin, was delivered to the individual learner. After one-hour chest compression-only HEROS Remote online training, the learners participated in-depth survey on their experiences of HEROS Remote online training.

Results A total 152 learners (92.7%) responded to the survey. Overall, 88.1% of the learners were satisfied with the HEROS Remote training and 85.5% responded that they would recommend online training to others. Majority of the learners (37.3% strongly agree; 41.3% agree) also agreed with the easiness of using the HEROS Remote app. Manikin delivery service was highly satisfactory (97%). However, major challenge for this online solution was that the quality of the training highly depended on internet connectivity.

Conclusion This study provides evidence of the feasibility and acceptability of a novel online, real-time CPR training solution. Further research is needed to investigate the effectiveness of online CPR training versus face-to-face training.
