Vital capacity is the amount of air that the lungs can expel after having been filled completely. The vital capacity represents the change in volume from completely emptied lungs to completely filled lungs. In human medicine, vital capacity is an important measure of a person’s respiratory health.
Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume , tidal volume , and expiratory reserve volume .
The vital capacity can be measured using a wet or regular spirometer. The vital capacity of a typical adult is between 3 and 5 liters. Factors that affect a person’s vital capacity include age, sex, height, weight, and ethnicity.
Vital capacity – the volume expired, calculated from the X-axis; Shape of the curve – ‘spooning’ in obstructive disease, small overall loop in restrictive disease
Vital capacity (VC) is the amount of air a person can move into or out of his or her lungs, and is the sum of all of the volumes except residual volume (TV, ERV, and IRV), which is between 4000 and 5000 milliliters.
The vital capacity is the total volume of air that can be expired after a maximum inhalation or maximum air that a person can breathe in after forced expiration. It is an important measure of a person’s respiratory health. A decreased vital capacity is an indication of restrictive lung disease where the lungs cannot expand completely.
The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. It is the sum of the expiratory reserve volume, tidal volume, and inspiratory reserve volume.
Vital capacity (VC) is the maximum amount of air that a person can exhale after inhaling as much air as possible. It is also the sum of tidal volume and the inspiratory and expiratory reserve volumes, which capture the differences between normal breathing and maximal breathing.
Vital capacity (VC) is the maximum amount of air that can be breathed out after the complete filling of the lungs following maximum inhalation. It is usually between three and five liters in normal individuals. It is the sum of tidal volume (V), inspiratory reserve volume (IRV), and expiratory reserve volume (ERV).
Vital capacity (VC) is the summation of TV, IR, and ERV. It represents the total air exhaled after maximum inhalation. Functional residual capacity (FRC) is the residual volume plus expiratory reserve volume.
