The skin is able of sustaining pressure on the arterial side of around 32 - 34mmHg for only a small duration of time. External pressure must exceed the arterial capillary pressure (32 mmHg) to impede blood flow and must be greater than the venous capillary closing pressure (8 to 12 mmHg) to impair the return of venous blood. The occluding the blood supply, tissue distortion also damage the lymphatic flow, which leads to the stagnated of body waste products, material and enzymes in the damaged tissue.
