The aim of this study is to examine the effect of virtual reality glasses, a non-pharmacological method used in pain and anxiety management in nursing practices, on the pain, anxiety, and vital parameters perceived by patients undergoing their first dressing change after open heart surgery. Additionally, the study aims to obtain information about the safety of the virtual reality application. The primary questions this study seeks to answer are as follows:

Does the virtual reality headset application reduce the pain participants feel during the procedure?

Does the application reduce participants' anxiety levels during the procedure?

Does the virtual reality application have a positive effect on vital signs (pulse, blood pressure, etc.)?

Do participants experience any side effects or medical problems during this application?

Researchers will compare the group that received virtual reality glasses during the first dressing change after open-heart surgery with the standard care (control group) to evaluate the effects of the intervention.
