Prognosår
Prognosår, also known as pressure ulcers or pressure sores, are localized injuries to the skin and underlying tissue that develop when persistent pressure is applied to the skin over bony prominences. These areas are particularly vulnerable due to reduced blood flow, which impairs healing and increases the risk of tissue damage. Prognosår commonly occur in individuals who are bedridden, wheelchair-bound, or have limited mobility, as prolonged pressure disrupts normal circulation and leads to tissue necrosis.
The development of prognosår is influenced by several factors, including prolonged pressure, friction, shear forces, moisture,
Prevention strategies focus on relieving pressure through regular repositioning, using supportive surfaces like mattresses or cushions
Prognosår can affect individuals of all ages but are most commonly seen in elderly patients or those
