Abstract：Objective To explore the feasibility and effectiveness with which a new scenario simulation exercise model based on virtual simulation technology is used for organizing high-altitude physiological training in order to improve the quality and efficiency of high-altitude physiological training and update the training model.Methods Immersive high-altitude physiological training mission scripts were designed based on high-altitude emergencies,and corresponding evaluation criteria were established.Forty-four students of aviation medicine were divided into 3 groups randomly,with 14 or 15 students per group,to engage in training laid out in a scenario simulation exercise mode using virtual simulation technology alone or using traditional methods.After training,such indicators as changes in students' physiological parameters,mastery of skills and levels of satisfaction were analyzed.Results During the pressure breathing training,the differences in the total scores of physiological parameters,increases of systolic blood pressure,scores of subjective feelings and those of index recovery times between the three groups of trainees were statistically significant(F=4.139,7.160,5.770,P=0.023,0.002,0.006).The trainees in the scenario simulation training group scored higher than those in the traditional mode group(P=0.019,0.001,0.005).The differences in scores of indicators of training effect between the three groups were also of statistical significance(F=4.139～27.452,all P＜0.05).The trainees in the scenario simulation training group compared favorably with the traditional mode group and the virtual simulation platform group in terms of the total score of training,enthusiasm for training,subjective feelings,and mastery of knowledge and skills(all P＜0.05).Conclusion Scenario simulation exercises based on virtual simulation technology can effectively improve the quality and efficiency of high-altitude physiological training.This study is expected to provide a new line of thought for improving the ability of aviation health care givers to offer medical support and for updating high-altitude physiological training modes.
