VR Interventions to Reduce the Prevalence of Delirium in ICU Patients

Delirium is an extremely common complication in mechanically ventilated ICU patients, which can decrease the patients\' cognitive function, prolong hospitalization, and even increase mortality. But there is currently no validated treatment for delirium. Therefore, this study aims to build a multi-modal virtual reality (VR) intervention environment to conduct comprehensive interventions in psychological, physiological, and cognitive aspects for ICU mechanically intubated patients, which will be used to improve the hospitalization experience, reduce the prevalence of delirium, and decrease the duration of ICU stay of patients on mechanical ventilation.
