| minute volume | The volume of any gas or fluid moved per minute; e.g., cardiac output or the respiratory minute volume. (05 Mar 2000) |
|---|---|
| closing volume | The lung volume at which the dependent lung zones cease to ventilate presumably as a result of airway closure. (12 Dec 1998) |
| plasma volume | Volume of plasma in the circulation. It is usually measured by indicator dilution techniques. (12 Dec 1998) |
| pressure-volume index | Method of evaluating the cerebrospinal fluid hydrodynamics. (05 Mar 2000) |
| specimen interaction volume | <microscopy> The volume inside the specimen in which all specimen interactions occur during electron beam irradiation. (05 Aug 1998) |
| standard volume | The volume of an ideal gas at standard temperature and pressure, approximately 22.414 liters. (05 Mar 2000) |
| stroke volume | <physiology> The amount of blood pumped out of one ventricle of the heart as the result of a single contraction. A measure of the effectiveness of ventricular contraction. (16 Dec 1997) |
| distribution volume | The volume throughout which an added tracer substance appears to have been evenly distributed, calculated by dividing the amount of tracer added by its concentration after equilibration. (05 Mar 2000) |
| inspiratory reserve volume | The extra volume of air that can be inspired with maximal effort after reaching the end of a normal, quiet inspiration. Common abbreviation is irv. (12 Dec 1998) |
| interstitial lung disease with increased volume | <radiology> Cystic fibrosis (CF), eosinophilic granuloma (EG), lymphangioleiomyomatosis (LAM) (12 Dec 1998) |
| tidal volume | The volume of air inspired or expired during each normal, quiet respiratory cycle. Common abbreviations are tv or v with subscript t. (12 Dec 1998) |
| elution volume | <chemistry> The amount of eluant which has passed through the column in column chromatography before a particular peak in an elution profile appears, or before a specific substance of interest comes out with the eluant, separated out of the original mixed substance. (09 Oct 1997) |
| end-diastolic volume | The amount of blood in the ventricle immediately before a cardiac contraction begins; a measurement of cardiac filling between beats, related to diastolic function. (05 Mar 2000) |
| end-systolic volume | The amount of blood in the ventricle at the end of the cardiac ejection period and immediately preceding the beginning of ventricular relaxation; a measurement of the adequacy of cardiac emptying, related to systolic function. (05 Mar 2000) |
| erythrocyte volume | Volume of circulating erythrocytes. It is usually measured by radioisotope dilution technique. (12 Dec 1998) |
