Witryna14 paź 2013 · Patient repositioning when the skin is moist, e.g., due to sweat or urine may cause skin breakdown since wetness increases the skin-support coefficient of friction (COF) and hence also the shear stresses that are generated in the skin when the patient is being moved. This everyday hospital scenario was never studied … WitrynaThe tolerance of soft tissue for pressure and shear also may be affected by microclimate, nutrition, perfusion, co-morbidities, and condition of the soft tissue. …
