Episode 053 Microclimate in context: optimising skin conditions


Listen Later

Until recently our understanding of pressure ulcer aetiology had made little significant progress since the classic studies of the early 1960?s. These landmark experiments attempted to define the relationship between tissue

damage, the magnitude of external pressures and the duration of their application. Other extrinsic factors have also been considered to increase skin and soft tissue vulnerability to prolonged or high external loads, of
these the local microclimate (for example temperature and humidity) at the skin-support surface interface has long been viewed as contributing to pressure ulcer development. As with shear forces, microclimate parameters
have been challenging to quantify. In consequence little systematic progress has been made towards reducing any deleterious effects caused by changes in skin temperature or humidity.
