Pressure ulcers (also known as decubitus ulcers or bedsores) are injuries to the skin or underlying tissue. They occur due to pressure applied to the tissue resulting in partial or complete blood flow blockage of the blood supply to soft tissue. Pressure ulcers most commonly develop in persons who are not able to move on their own. Fortunately these injuries are easily preventable and treatable if detected early. Primary prevention is to redistribute pressure by turning the patient regularly. In addition to turning and re-positioning, eating a balanced diet with adequate protein and keeping the skin free from exposure to contaminants is also helpful.
In a microgravity environment crewmembers would have minimal pressure applied to the skin and soft tissue, which would greatly reduce the incidence and severity of pressure ulcers during a torpor state.
