Existing evidence indicates that this technology has basic safety and feasibility in such critically ill patients. However, current research generally has limitations such as small sample size, lack of support from high-quality randomized controlled trials, relatively single virtual reality content, insufficient personalization, and insufficient validation of the reliability and validity of related usability evaluation tools in the ICU population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Virtual reality technology has shown significant potential in preventing delirium in ICU patients with mechanical ventilation. Future research should focus on constructing systematic and individualized virtual reality intervention programs, developing and verifying assessment tools suitable for local ICU patients, and further
