Which term describes a skin lesion caused by ischemia of the integument secondary to pressure?

The term that describes a skin lesion caused by ischemia of the integument secondary to pressure is known as a pressure ulcer. Pressure ulcers, often referred to as bedsores or decubitus ulcers, occur when there is prolonged pressure on the skin, particularly over bony prominences. This continuous pressure impairs blood flow to the affected area, leading to ischemia and subsequently tissue damage.

Understanding this condition is critical in physical therapy as it often relates to patient mobility, positioning, and care strategies aimed at preventing skin breakdown. It also emphasizes the importance of regular assessment and intervention to maintain skin integrity, especially in individuals with limited mobility or sensation.

Other terms like eczema and dermatitis refer to inflammatory skin conditions often associated with allergies or irritants, rather than pressure-induced ischemia. Skin abrasions are superficial injuries to the skin caused by friction or scraping and are not associated with ischemia from pressure.
