Pressure ulcer is defined by the National Pressure Ulcer Advisory Panel (NPUAP) and European Pressure Ulcer Advisory Panel (EPUAP) as “localized injury to the skin and/or underlying tissue usually over a bony prominence as a result of pressure, or pressure in combination with shear and/or friction.” People most at risk of pressure ulcers are those with a medical condition that limits their ability to change positions, requires them to use a wheelchair, or confines them to a bed for a long time.1 Pressure ulcers result when increased pressure exceeds the local capillary pressure. Depending on patient’s severity of illness, less pressure may be adequate enough to obstruct capillary blood flow and can result in decreased oxygen delivery to tissues and as a result pressure ulcer can develop within 2 to 6 hours. If patients who are at risk of pressure ulcer are identified, effective measures will be taken to prevent its occurrence 2.
