A pressure ulcer is a localized injury to A pressure ulcer is a localized injury to the skin and/or underlying tissue usually the skin and/or underlying tissue usually over a bony prominence, as a result of over a bony prominence, as a result of pressure, or pressure in combination with pressure, or pressure in combination with shear and/or friction.shear and/or friction.

Pressure UlcersPressure Ulcers
Tissues receive oxygen and nutrients Tissues receive oxygen and nutrients and eliminates metabolic wastes via the and eliminates metabolic wastes via the bloodblood
Any factor that interferes with this Any factor that interferes with this affects cellular metabolism and cell lifeaffects cellular metabolism and cell life
Pressure affects cellular metabolism by Pressure affects cellular metabolism by decreasing or stopping tissue decreasing or stopping tissue circulation resulting in tissue ischemiacirculation resulting in tissue ischemia
Causes of Pressure Causes of Pressure UlcersUlcers
Pressure > ischemia > edema > Pressure > ischemia > edema > inflammation > small vessel inflammation > small vessel thrombosis > cell deaththrombosis > cell death
Shear – trauma caused by tissue Shear – trauma caused by tissue layers sliding across each other, layers sliding across each other, results in disruption or angulation of results in disruption or angulation of blood vesselsblood vessels

Skin has a greater ability to tolerate Skin has a greater ability to tolerate ischemia than does muscle, hence ischemia than does muscle, hence true pressure ulcers begin at bone true pressure ulcers begin at bone with pressure related to muscle with pressure related to muscle ischemia eventually coming through ischemia eventually coming through to epidermis (Shear injury) Sacrum to epidermis (Shear injury) Sacrum and heels most susceptibleand heels most susceptible
