|---|---|
| pressure sense | The faculty of discriminating various degrees of pressure on the surface. Synonym: baresthesia, piesesthesia, weight sense. (05 Mar 2000) |
| pressure sore | <dermatology> A chronic ulcer that appears in pressure areas in debilitated patients confined to bed or otherwise immobilised, due to a circulatory defect from the enhanced tissue pressure in high-contact areas, often occurring over a bony prominence (for example sacral decubitus). (27 Sep 1997) |
| pressure stasis | Cyanotic asphyxia due to trauma; the extravasation of blood into the skin and conjunctivae, produced by a sudden mechanical increase in venous pressure, analogous to the Rumpel-Leede test; it is common in those who have been hanged, and is seen occasionally in crush injuries. Synonym: pressure stasis. (05 Mar 2000) |
| pressure urticaria | Urticaria of unknown aetiology occurring after local pressure on the skin. (05 Mar 2000) |
| pressure-volume index | Method of evaluating the cerebrospinal fluid hydrodynamics. (05 Mar 2000) |
| high blood pressure | <cardiology> Persistently high arterial blood pressure. Hypertension may have no known cause (essential or idiopathic hypertension) or be associated with other primary diseases (secondary hypertension). This condition is considered a risk factor for the development of heart disease, peripheral vascular disease, stroke and kidney disease. (29 Sep 1997) |
| high-pressure | 1. Having or involving a pressure greatly exceeding that of the atmosphere; said of steam, air, water, etc, and of steam, air, or hydraulic engines, water wheels, etc. 2. Urgent; intense; as, a high-pressure business or social life. High-pressure engine, an engine in which steam at high pressure is used. It may be either a condensing or a noncondensing engine. Formerly the term was used only of the latter. See Steam engine. Source: Websters Dictionary (01 Mar 1998) |
| high-pressure liquid chromatography | <investigation> A lab technique, a type of column chromatography, which uses a combination of several separation techniques to separate substances at higher resolution. Extremely sharp peaks on the elution profile can be produced with high-performance liquid chromatography (HPLC). (09 Oct 1997) |
| high pressure nervous syndrome | <syndrome> A syndrome of tremors, nausea, dizziness, and decreased motor and mental performance which develops in those who dive deeply (c. 1000 ft) usually breathing a mixture of oxygen and helium. Nitrogen is not a factor as it is in inert gas narcosis. (12 Dec 1998) |
| selection pressure | Impact of effective reproduction due to environmental impact on the phenotype. (05 Mar 2000) |
| pulp pressure | The pressure in the dental pulp cavity associated with extracellular fluid pressure, but showing pulsatile variations during the cardiac cycle because of the encasement of the pulp within the tooth. (05 Mar 2000) |
| pulse pressure | The variation in blood pressure occurring in an artery during the cardiac cycle; it is the difference between the systolic or maximum and diastolic or minimum pressure's. (05 Mar 2000) |
| hydrostatic pressure | The pressure exerted by a liquid as a result of its potential energy, ignoring its kinetic energy; frequently used to distinguish a true pressure from an osmotic pressure or to emphasize the variation in pressure in a column of fluid due to the effect of gravity. (05 Mar 2000) |
| solution pressure | The force driving atoms or molecules to leave a solid particle and enter into solution (i.e., to dissolve). (05 Mar 2000) |
