What is a pressure ulcer?
A pressure ulcer is damage to the skin and the deeper layer of tissue under the skin. This happens when pressure is applied to the same area of skin for a period of time and cuts off its blood supply. It is more likely if a person has to stay in a bed or chair for a long time. Pressure ulcers are sometimes called 'bedsores' or 'pressure sores'.
Without care, pressure ulcers can become very serious. They may cause pain, or mean a longer stay in hospital. Severe pressure ulcers can badly damage the muscle or bone underneath the skin, and can take a very long time to heal.
