Pressure sores, also known as decubitus ulcers and pressure ulcers, are caused by long-term pressure on the patient’s local tissues, which affects blood circulation and leads to persistent ischemia, hypoxia, and malnutrition of the local skin and subcutaneous tissues, resulting in tissue ulceration and necrosis. Skin pressure ulcers are a common problem in rehabilitation treatment and care. Clinical manifestations include local erythema, numbness, pain, rupture, necrosis, and ulceration of the pressurized area. Some develop systemic symptoms and even sepsis due to local infection.
