Pressure Ulcer

A pressure ulcer — also called a bedsore or pressure sore — is an injury to the skin and underlying tissue caused by prolonged pressure, often combined with friction or moisture. They develop where bone is close to the skin, such as the tailbone, hips, heels, and elbows, in people who sit or lie in one position for long periods.

Who is at risk

Seniors with limited mobility, those who use a wheelchair full-time, and people who are bedbound are most at risk, especially if they also have fragile skin, poor nutrition, or incontinence.

Prevention

The keys are relieving and redistributing pressure and repositioning regularly (often every 1-2 hours for someone bedbound). A ventilated or gel pressure-relief cushion helps for sitting, and a pressure-redistributing mattress for lying down. Keeping skin clean and dry, eating well, and inspecting at-risk areas daily all matter. Anyone with an existing or high-risk pressure sore should be evaluated by a wound-care nurse or occupational therapist, who may recommend a clinical-grade alternating-pressure system.
