Introduction
Pressure ulcers, also sometimes known as bedsores or pressure sores, are a type of injury that affects areas of the skin and underlying tissue.
Symptoms of pressure ulcers
Depending on the severity of a pressure ulcer, symptoms can include red or discoloured skin, itchy skin, blisters or an open wound.
Causes of pressure ulcers
Pressure ulcers are caused by sustained pressure being placed on a particular part of the body. This pressure interrupts the blood supply to the affected area of skin.
Diagnosing pressure ulcers
Pressure ulcers are easily diagnosed by visual examination. However, pressure ulcer management aims to prevent ulcers occurring in the first place.
Treating pressure ulcers
Treatment options for pressure ulcers include regularly changing position, special mattresses and dressings, and, in severe cases, surgery.
Complications of pressure ulcers
Even with the best possible medical care, complications can arise from grade three or grade four pressure ulcers and can be occasionally life-threatening.
