Pressure sores. Prevention and step-up management. 1977

P S Tepperman, and C S De Zwirek, and A L Chiarcossi, and J Jimenez

The tissue changes that produce pressure sores may be described as occurring in five stages: blanching hyperemia, nonblanching hyperemia, blister and eschar formation, clean ulcer, and infected ulcer. Tissue breakdown is a direct response to external pressure, friction, or shearing force. Prevention of pressure sores comes down to identifying intrinsic and extrinsic risk factors and taking all possible steps to circumvent them. A "step-up" approach to management takes its name from the components surface agents, thermal agents, exposure, ultraviolet light, and pressure redistribution.

UI	MeSH Term	Description	Entries
D011187	Posture	The position or physical attitude of the body.	Postures
D003668	Pressure Ulcer	An ulceration caused by prolonged pressure on the SKIN and TISSUES when one stays in one position for a long period of time, such as lying in bed. The bony areas of the body are the most frequently affected sites which become ischemic (ISCHEMIA) under sustained and constant pressure.

D006940	Hyperemia	The presence of an increased amount of blood in a body part or an organ leading to congestion or engorgement of blood vessels. Hyperemia can be due to increase of blood flow into the area (active or arterial), or due to obstruction of outflow of blood from the area (passive or venous).

D012306	Risk	The probability that an event will occur. It encompasses a variety of measures of the probability of a generally unfavorable outcome.	Relative Risk,Relative Risks,Risk, Relative,Risks,Risks, Relative
D014467	Ultraviolet Therapy	The use of ultraviolet electromagnetic radiation in the treatment of disease, usually of the skin. This is the part of the sun's spectrum that causes sunburn and tanning. Ultraviolet A, used in PUVA, is closer to visible light and less damaging than Ultraviolet B, which is ionizing.
