What is a primary cause of pressure ulcers among immobile residents?

Pressure ulcers, also known as bedsores or decubitus ulcers, develop primarily due to sustained pressure on specific areas of the body, particularly in immobile individuals. When a person cannot change their position, areas that bear weight, such as the heels, sacrum, and hips, experience continuous pressure. This pressure restricts blood flow to the skin and underlying tissues, leading to tissue damage and ultimately the formation of ulcers.

Maintaining mobility or regularly repositioning immobile residents can help alleviate pressure on these vulnerable areas, reducing the risk of ulcer development. Effective care strategies include using specialized mattresses, repositioning schedules, and ensuring that any pressure-relieving devices are employed correctly. Thus, understanding the mechanics of pressure ulcer formation highlights the critical importance of managing pressure to prevent these injuries in immobile residents.
