Residual volume: the volume of air remaining in the lungs after a maximal exhalation: ERV: Expiratory reserve volume: the maximal volume of air that can be exhaled from the end-expiratory position: IRV: Inspiratory reserve volume: the maximal volume that can be inhaled from the end-inspiratory level: IC: Inspiratory capacity: the sum of IRV and ...
Actual volume of the lung including the volume of the conducting airway. FVC: Forced vital capacity: the determination of the vital capacity from a maximally forced expiratory effort: FEV t: Forced expiratory volume (time): a generic term indicating the volume of air exhaled under forced conditions in the first t seconds: FEV 1: Volume that has ...

It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC). [1] [2] A person's vital capacity can be measured by a wet or regular spirometer.
FRC is the sum of expiratory reserve volume (ERV) and residual volume (RV) [2] and measures approximately 3000 mL in a 70 kg, average-sized male. [1] [2] It cannot be estimated through spirometry, since it includes the residual volume.
In respiratory physiology, specific ventilation is defined as the ratio of the volume of gas entering a region of the lung (ΔV) following an inspiration, divided by the end-expiratory volume (V 0) of that same lung region:
