🛏️💤 Decubitus refers to the formation of pressure ulcers, commonly known as bedsores, due to prolonged pressure on specific areas of the body while lying in bed or sitting for extended periods. These ulcers typically develop in individuals who are immobile or have limited mobility, leading to reduced blood flow and tissue damage. Proper care and frequent repositioning are essential to prevent decubitus and promote healthy skin integrity. 💤🛏️
