How long it would take for a pressure ulcer to form. Do they appear rather quickly?

In brief: A few hours

Complicated question, but it is generally believed that unrelieved pressure that is high enough to cut off blood flow for two hours can cause a pressure sore.
This is why patients who are prone to pressure sores should be repositioned every two hours or placed on a specialized bed that eliminates pressure on the skin.

In brief: 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.
