Objective To explore the learning experience of using mixed-view standardized videos in cardiopulmonary resuscitation (CPR) training. Methods From September to December 2022, a questionnaire survey was conducted among 60 medical students who participated in CPR training at Peking University Third Hospital and 144 medical staff in the emergency department of the same hospital to understand their feedback on mixed first-person and third-person view videos. Data were analyzed using rank sum tests and chi-squared tests. Results The satisfaction score (out of 5 points) of medical staff with mixed-view videos was higher than that of students [5.0(0) points vs. 5.0(1.0) points]. The satisfaction rate with the demonstration effect of breathing check in first-person view videos and the ″picture-in-picture″ form of mixed-view videos was higher than that of students [93.8%(135/144) vs. 83.3%(50/60), 79.2%(114/144) vs. 63.3%(38/60)], and the differences were statistically significant (all P<0.05). The satisfaction rate of medical staff in demonstration effect of response check in first-person view video was 88.9% (128/144), and the satisfaction rate of students was 80.0% (48/60), with no statistically significant difference (P>0.05). Medical staff considered that the main advantage of mixed-view videos was intuitiveness [67/144 (46.5%)], while the main disadvantage was that the first-person view screen was too small [15/144 (10.4%)]. Students considered that the main advantage of mixed-view videos was intuitiveness [22/60 (36.7%)], while the main disadvantage was that two synchronized images distracted attention [12/60 (20.0%)]. Conclusions The mixed-view CPR training video can integrate the advantages of different view images and may become an important type of standardized training video in the future.
