What is a decubitus ulcer?

A decubitus ulcer, commonly known as a pressure sore or bed sore, occurs when there is prolonged pressure on the skin, particularly over bony areas of the body. This sustained pressure restricts blood flow to the affected skin tissue, leading to tissue breakdown and ulceration.

These ulcers are typically seen in individuals who are immobile or have limited mobility, such as those confined to a bed or wheelchair for extended periods. The skin overlying the pressure point becomes compromised, which can lead to pain, infection, and further complications if not properly managed.

Understanding decubitus ulcers is crucial for caregivers because prevention strategies, such as regular repositioning, skin care, and adequate nutrition, can significantly reduce the risk of these injuries in at-risk populations.
