Construction of a Postoperative Delirium Experience System for Nursing Student Education Using VR and HMD

Abstract

In this study, we created a VR system using an HMD that allows nursing college students to simulate delirium, and clarified the physiological and psychological changes that occur when simulating delirium. The subjects were 18 males and 18 females, 6 from each of the grades 2 to 4 of the nursing school. The subjects were 18 males and 18 females, 6 from each grade of nursing school, from the second year to the fourth year. In this system, we created a VR video image to simulate postoperative delirium, which can be viewed on an HMD. Physiological data was obtained by showing the delirium video image after the subjects were sufficiently accustomed to viewing the VR. Autonomic functional activity (LF/HF) was measured in order to understand the stress level during video viewing. For psychological data, we used the Profile of Mood Scale (POMS2), a mood rating scale that can determine current mood before and after video viewing. The results of the analysis of the physiological data showed no significant differences. In the results of the analysis of psychological data, there were significant differences in all items. Based on these results, this study was judged to be useful as an experience for nursing students to attend to delirium patients.
