| pressure | 1. The act of pressing, or the condition of being pressed; compression; a squeezing; a crushing; as, a pressure of the hand. 2. A contrasting force or impulse of any kind; as, the pressure of poverty; the pressure of taxes; the pressure of motives on the mind; the pressure of civilization. "Where the pressure of danger was not felt." (Macaulay) 3. Affliction; distress; grievance. "My people's pressures are grievous." (Eikon Basilike) "In the midst of his great troubles and pressures." (Atterbury) 4. Urgency; as, the pressure of business. 5. Impression; stamp; character impressed. "All saws of books, all forms, all pressures past." (Shak) 6. <mechanics> The action of a force against some obstacle or opposing force; a force in the nature of a thrust, distributed over a surface, often estimated with reference to the upon a unit's area. Atmospheric pressure, Center of pressure, etc. See Atmospheric, Center, etc. <engineering> Back pressure, pressure which resists the motion of the piston, as the pressure of exhaust steam which does not find free outlet. Fluid pressure, pressure like that exerted by a fluid. It is a thrust which is normal and equally intense in all directions around a point. Pressure gauge, a gauge for indicating fluid pressure; a manometer. Origin: OF, fr. L. Pressura, fr. Premere. Source: Websters Dictionary (01 Mar 1998) |

| pressure amaurosis | A loss of vision occurring a few seconds after intraocular pressure exceeds systolic pressure of retinal arteries. (05 Mar 2000) |
| pressure anaesthesia | Loss of sensation produced by pressure applied to a nerve. Synonym: compression anaesthesia. (05 Mar 2000) |
| pressure atrophy | The wasting of hard or soft tissue resulting from excessive pressure applied to tissue by a denture base. (05 Mar 2000) |
| pressure collapse | Pulmonary collapse due to external compression of the lung, as by a pleural effusion or pneumothorax. (05 Mar 2000) |
| pressure-controlled respirator | A respirator that provides a predetermined pressure to gases during inhalation, the volume of gas moved being variable, depending upon resistance. (05 Mar 2000) |
| pressure dressing | A dressing by which pressure is exerted on the area covered to prevent the collection of fluids in the underlying tissues; most commonly used after skin grafting and in the treatment of burns. (05 Mar 2000) |
| pressure epiphysis | A secondary centre of ossification in the articular end of a long bone. (05 Mar 2000) |
| pressure gangrene | <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, intraocular | The pressure created by the continual renewal of fluids within the eye. The intraocular pressure is increased in glaucoma. In acute angle-closure glaucoma, the intraocular pressure rises because the canal into which the fluid in the front part of the eye normally drains is suddenly blocked. In chronic glaucoma, there is a gradual imbalance between the production and removal (resorption) of the fluid in the back part of the eye (with supply exceeding demand). (12 Dec 1998) |
| pressure palsy | Paralysis due to compression of a nerve, nerve trunk, or spinal cord. Synonym: pressure palsy. (05 Mar 2000) |
| pressure paralysis | Paralysis due to compression of a nerve, nerve trunk, or spinal cord. Synonym: pressure palsy. (05 Mar 2000) |
| pressure plethysmograph | A plethysmograph applied to part of the body, e.g., a limb segment, and arranged so that volume is measured during temporary application of sufficient pressure to the part to empty its blood vessels, a body plethysmograph in which changes of body volume are measured in terms of the consequent changes in air pressure in the body plethysmograph. Volume-displacement plethysmograph, a plethysmograph, usually a body plethysmograph, in which changes in volume displace a corresponding volume into or out of a very compliant measuring device, such as a Krogh spirometer or integrating flowmeter.
