— Explanation · 中文詳解 —
壓瘡（Pressure injury）形成的主因為持續性壓力導致組織缺血。在平躺（supine）姿勢下，薦骨（Sacrum）部位的骨突處承受了上半身大部分的重量，且該處皮膚較薄，軟組織覆蓋少，因此是發生深層組織損傷（DTI）的高風險區。護理師必須執行每兩小時翻身（repositioning）並檢查骨突處。
In the supine position, the sacrum bears the majority of body weight and has thin skin with minimal soft tissue coverage, making it highly susceptible to pressure injuries and deep tissue damage. While other sites like the lateral malleolus and greater trochanter are at risk during side-lying, and ischial tuberosities during sitting, the sacrum is the primary concern for clients remaining flat.
