The Effects of Virtual Reality Glasses on Vital Signs and Anxiety in Patients Undergoing Colonoscopy

Virtual reality (VR) glasses have a detachable screen frame compatible with smartphones. A VR headset has earphones and sensors that track the user's head movements, giving them the impression that they are moving around in a virtual environment. The investigators used a smartphone and VR glasses to perform the intervention. They connected the phone to the VR headset via a 360 degree VR video app. Experimental participants wore the VR glasses and watched a 360 degree VR video of nature scenes with ambiance music during colonoscopy. They put on the VR glasses right before the procedure and took them off right afterward.
