Overview

This is a pilot feasibility study examining the use of immersive virtual reality (VR) in adult intensive care unit (ICU) patients. The study evaluates whether brief, non-interactive VR sessions delivered using a commercially available standalone head-mounted display with calming, nature-based content can be delivered safely and effectively within routine SICU workflow. Exploratory objectives assess whether VR sessions are associated with changes in anxiety, agitation, delirium, pain, and sedative medication requirements. This research is not intended to evaluate the safety or effectiveness of the headset and/or the specific VR software used for the research
