| phrenic pressure test | Pressure is made on the phrenic nerve on each side, above the clavicles where the nerve passes over the scalenus anticus muscle; if pain is felt and the patient inclines his head to the painful side, the problem is in the pleural space; if his head does not incline to one side, the problem is in the abdominal cavity.

| postoperative pressure alopecia | Loss of hair over a circumscribed area usually on the posterior scalp, resulting from continuous pressure on the occiput in a lengthy operative procedure, or unconsciousness following a drug overdose. (05 Mar 2000) |
| 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) |
