low blood pressure
| 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) |
| pulmonary capillary wedge pressure | The pressure obtained when a catheter is passed from the right side of the heart into the pulmonary artery as far as it will go and "wedged" into an end artery. PCWP is measured by letting pulmonary blood flow guide a balloon-flotation catheter into a small pulmonary end artery. The pressure distal to the wedged catheter is an approximation of cardiac left atrial pressure. The pressure recorded with the balloon deflated is pulmonary artery pressure. (05 Mar 2000) |
| selection pressure | Impact of effective reproduction due to environmental impact on the phenotype. (05 Mar 2000) |
| pulmonary pressure | The blood pressure in the pulmonary artery. (05 Mar 2000) |
| pulmonary wedge pressure | The blood pressure as recorded after wedging a catheter in a small pulmonary artery; believed to reflect the pressure in the pulmonary capillaries. (12 Dec 1998) |
| 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) |
| sound pressure level | A measure of sound energy relative to 0.0002 dynes/cm2, expressed in decibels. (05 Mar 2000) |
| standard pressure | The absolute pressure to which gases are referred under standard conditions (STPD), i.e., 760 mm Hg, 760 torr, or 101,325 newtons/m2 (i.e., 101,325 Pa). (05 Mar 2000) |
| negative end-expiratory pressure | A subatmospheric pressure at the airway at the end of expiration. (05 Mar 2000) |
