Exploring the effect of virtual reality relaxation environment on white coat hypertension in blood pressure measurement.

A phenomenon called White Coat Hypertension (WCH) often occurs when measuring blood pressure (BP) in a real medical environment. Utilizing virtual reality (VR) technology to present appropriate relaxation scenes can isolate the real medical environments and may provide a new method to avoid WCH and improve the accuracy of BP measurement. In this study, we designed four immersive VR relaxation scenes and conducted an experiment to explore the role of VR scenes in eliminating/detecting WCH in BP measurement. Results from the current sample showed that both systolic BP and diastolic BP measured in the simulated medical environment were significantly higher than the baseline level and the VR scene condition, while there were no significant differences between the BPs measured in VR scenes and the baseline level. It can be concluded that VR provides an effective approach to avoid WCH in BP measurement by visually and aurally isolating the real environment and assisting relaxation and provides a new approach to detect the occurrence of WCH by the comparison of BPs measured in the VR scene condition and real medical environments.
