The pathogenesis of pressure sores is local tissue pressure above that of perfusion pressure produces ischemic necrosis that is directly propoional to the duration and degree of pressure. Muscle and fat are more susceptible to pressure than skin. Bed-bound patient should be turned at least every 2 hours(not every 8 hours), with the wheelchair-bound patient being taught to lift themselves off their seat for 10 seconds every 10 minutes. A turning schedule with a signing sheet will help ensure that the patient gets turned and, thus, help prevent pressure ulcers.
