VR Interventions to Reduce the Prevalence of Delirium in ICU Patients

The goal of this clinical trial is to learn the effect of Virtual Reality Family Support System (VRFS) on reducing delirium in ICU mechanically ventilated patients. The main question it aims to answer is: ·Using VRFS for participant intervention, can it reduce the incidence of delirium and improve clinical outcomes? Researchers will investigate whether the implementation of VRFS can reduce the number of delirium days and improve clinical outcomes. Participants will: * Receive the VRFS intervention until the endotracheal tube (ETT) is removed. * Have physiological data collected, including EEG, oxygen saturation levels, ECG, and blood pressure. * Keep a diary of delirium, dosage of sedative and analgesic drugs, the duration of mechanical ventilation, and ICU stays.
