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.
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 been exhaled at the end of the first second of forced expiration: FEF x: Forced expiratory flow related to some portion of the FVC curve; modifiers refer to amount of FVC already exhaled ...
TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)

Output of a spirometer. 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.
