摘要
目的探索在心肺复苏培训中使用混合视角教学视频的学习体验。方法2022年9至12月,对在北京大学第三医院参加心肺复苏培训的60名医学生和北京大学第三医院急诊科144名医护人员开展问卷调查,了解其对第一人称和第三人称混合视角教学视频的反馈。数据采用秩和检验和χ2检验进行统计分析。结果医护人员对混合视角教学视频的满意度评分(满分5分)高于学生[5.0(0)分比5.0(1.0)分],对第一人称视角视频画面的呼吸判断演示效果和混合视角的“画中画”形式的满意率均高于学生[93.8%(135/144)比83.3%(50/60)、79.2%(114/144)比63.3%(38/60)],其差异均具有统计学意义(均P<0.05)。第一人称视角视频画面的意识判断演示效果的医护人员满意率为88.9%(128/144),学生满意率为80.0%(48/60),其差异无统计学意义(P>0.05)。医护人员认为混合视角教学视频的主要优点是直观[67名(46.5%)],主要缺点是第一人称视角画面过小[15名(10.4%)]。学生认为混合视角视频的主要优点是直观[22名(36.7%)],主要缺点是2个同步画面会分散注意力[12名(20.0%)]。结论心肺复苏培训的混合视角教学视频能够融合不同视角画面的优势,未来可能成为标准化教学视频中的一个重要的类型。
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.
