In high-risk patients with pressure ulcers, a non-invasive measurement method is used to evaluate the indicators of skin changes in the area where pressure ulcers occur, and to derive the correlation between the measurement results, to establish a database of skin measurement indexes for patients with bedsores. The usefulness and necessity of the study will be explained to test subjects calculated based on the selection criteria and exclusion criteria, and test subjects will be recruited. If selected as a test subject, fill out the consent form and measure the temperature, color, erythema, and elasticity of the subject's normal skin area using non-invasive skin measurement equipment at the site of high risk of pressure ulcers in the Severance Hospital Dermatology Department I will compare and measure. Subjects visited the hospital twice at intervals of one month to conduct measurement.
