how long does it take for pressure ulcers to form?

1 doctor answer
Dr. Scott Bolhack

Duration for PUs: Pressure ulcers are due to 'enough' pressure to occlude the blood pressure of the microscopic capillaries. No one is sure how long it you must occlude these capillaries so that a pressure injury results in changes in the skin. It will vary from person to person because of multiple factors in addition to time: repeated episodes, moisture, nutrition, protein stores, ability to heal, diabetes mellitu.
