volume /vol·ume/ (vol´ūm) the measure of the quantity or capacity of a substance. Symbol V or V.
Mean corpuscular volume (MCV)
mean corpuscular volume (MCV),
mean corpuscular volume (MCV) (mēn kōr·pusˑ·ky
·lr välˑ·yōōm),
end-diastolic volume (EDV) the volume of blood in each ventricle at the end of diastole, usually about 120–130 mL but sometimes reaching 200–250 mL in the normal heart.
end-systolic volume (ESV) the volume of blood remaining in each ventricle at the end of systole, usually about 50–60 mL but sometimes as little as10–30 mL in the normal heart.
expiratory reserve volume the maximal amount of gas that can be exhaled from the resting end-expiratory level. Abbreviated ERV.
forced expiratory volume the fraction of the forced vital capacity that is exhaled in a specific number of seconds. Abbreviated FEV with a subscript indicating how many seconds the measurement lasted.
inspiratory reserve volume the maximal amount of gas that can be inhaled from the end-inspiratory position.
mean corpuscular volume the average volume of erythrocytes, conventionally expressed in cubic micrometers or femtoliters per red cell.
minute volume (MV) the quantity of gas exhaled from the lungs per minute; tidal volume multiplied by respiratory rate.
packed-cell volume (PCV), volume of packed red cells (VPRC) hematocrit.
residual volume the amount of gas remaining in the lung at the end of a maximal exhalation.
stroke volume the volume of blood ejected from a ventricle at each beat of the heart, equal to the difference between the end-diastolic volume and the end-systolic volume.
tidal volume the volume of gas inhaled and exhaled during one respiratory cycle.
| mean corpuscular volume n. Abbr. MCV The average volume of red blood cells in erythrocyte indices, calculated from the hematocrit and the red blood cell count. |
Mean corpuscular volume (MCV)
A measure of the average volume of a red blood cell.
Mentioned in: Red Blood Cell Indices
mean corpuscular volume (MCV),
an evaluation of the average volume of each red cell, derived from the ratio of the volume of packed red cells (the hematocrit) to the total number of red blood cells. The normal MCV is between 82 and 92μm3 in children and adults and 96 to 108μm3 in newborns.
mean corpuscular volume (MCV) (mēn kōr·pusˑ·ky
·lr välˑ·yōōm),n determination of the average volume of a single red blood cell, derived from the ratio of the hematocrit to the total number of red blood cells. The normal MCV range is 32% to 36% for adults and children and 32% to 34% in infants.
