Capillary closing pressure definition
WebFACT FILE Localised pressure is thought to contribute to pressure ulcer development by deforming skin and soft tissues, often between a bony structure and an external surface (such as a bed or a chair), thereby distorting cells, reducing blood flow and inducing ischaemia and necrosis. Although capillary closing pressure – ie the pressure ...

WebAn increase in the sensor temperature boils off a greater proportion of the vapour from the liquid held within it, increasing the vapour pressure in the sensor and capillary system. This increase in pressure is transmitted through the capillary to a bellows or diaphragm assembly at the opposite end (see Figure 7.1.3).
