Application of virtual simulation technology in the practical teaching of aviation cardiovascular physiology training-taking “pressure breathing training” as an example

AIM To explore the application effect of virtual simulation technology in practical teaching of aviation cardiovascular physiology training.

METHODS A control group (n=44) of aerospace clinical medicine students (grade 2019) was selected and subjected to ground pressure breathing training practical teaching methods. An experimental group (n=51) of aerospace clinical medicine students (grade 2020) was selected and subjected to ground training combined with on-board virtual simulation training practical teaching methods. After completion of the course, the effects of the two teaching methods was comprehensively compared through the indexes such as formative assessment, practical assessment, physiological parameter, and questionnaire surveys.

RESULTS Compared to the group undergoing solely ground-based pressurized breathing training, students undergoing practical teaching with the combination of virtual simulation technology achieved higher formative and practical assessment scores (all P<0.01). According to the evaluation criteria of aviation physiology training syllabus, the physiological parameters recorded during high pressure training process (400 mmH₂O、600 mmH₂O) in the experimental group were superior to the control group (P<0.05). The questionnaire survey indicated that the satisfaction of the experimental group was also higher than that in the control group (P<0.05).

CONCLUSION The application of virtual simulation technology in practical teaching system of the cardiovascular module in aviation physiology training can enhance students' understanding and mastery, break the limitations of traditional teaching methods, and improve the quality of practical teaching.
