| 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) |
| expiratory reserve volume | The extra volume of air that can be expired with maximum effort beyond the level reached at the end of a normal, quiet expiration. Common abbreviation is erv. (12 Dec 1998) |
| extracellular fluid volume | The fraction of body wate rnot in cells; about 25% of body weight. It consists of plasma water (4.5% of body weight), water between cells (interstitial water-lymph, 11.5% of body weight), water in dense bone and connective tissue (7.5% of body weight) and water secretions.See transcellular water, about 1.5% of body weight.. (05 Mar 2000) |
| flow-volume curve | The graph produced by plotting the instantaneous flow of respiratory gas against the simultaneous lung volume, usually during maximal forced expiration. (05 Mar 2000) |
| foliage volume | <botany> The space, expressed in cubic metres, occupied by a tree. (12 Nov 1997) |
| forced expiratory volume | Measure of the maximum amount of air during a forced vital capacity determination that can be expelled in a given number of seconds. It is usually given as fev followed by a subscript indicating the number of seconds over which the measurement is made, although it is sometimes given as a percentage of forced vital capacity. (12 Dec 1998) |
| left ventricular volume overload | <radiology> VSD, patent ductus arteriosus, mitral incompetence, aortic incompetence (12 Dec 1998) |
| lung volume measurements | Measurement of the amount of air that the lungs may contain at various points in the respiratory cycle. (12 Dec 1998) |
