Final answer:
Decubitus ulcers, or bedsores, result from prolonged pressure that leads to compromised circulation, commonly occurring in immobilized or bedridden individuals. Without intervention, this pressure can cause tissue necrosis and potentially fatal infections. Proper care, including repositioning and skin monitoring, is vital in their prevention.
Step-by-step explanation:
Decubitus ulcers, also known as pressure ulcers or bedsores, are injuries to skin and underlying tissue resulting from prolonged pressure on the skin. Decubitus ulcers typically occur on skin that covers bony areas of the body, such as the heels, ankles, hips, and tailbone. They are caused by the combination of pressure, friction, and shear forces that compromise circulation to these vulnerable areas.
The first sign of a bedsore is usually an area of skin that may feel warmer or cooler compared to adjacent tissue, appear reddish or discolored, and feel tender or painful. If pressure is not relieved, the skin may break down, leading to an ulcer. This is why frequent repositioning, proper support surfaces, and diligent skin care are essential in preventing the progression of these ulcers. If the compromised circulation to the affected area continues, it can lead to tissue death, known as necrosis, which can cause serious infections and significant health complications if not treated promptly.
