Pulmonary Function Tests

Tidal volume (TV): The amount of air inhaled and exhaled during a normal breath. A typical TV is 500 mL.
Inspiratory reserve volume (IRV): The maximum amount of air someone can inhale after a normal breath. A typical IRV is 3,100 mL.
Expiratory reserve volume (ERV): The maximum amount of air that can be exhaled after a normal exhalation. A typical ERV is 1,200 mL.
Residual volume (RV): The amount of air remaining in the lungs after a maximal exhalation. A typical RV is 1,200 mL.
Total lung capacity (TLC): The total volume of the lungs when fully inflated. This is calculated by adding the TV, IRV, ERV, and RV. A typical TLC is 6,000 mL.
Vital capacity (VC): The maximum amount of air a person can exhale after a maximal inhalation. This is calculated by adding the TV, IRV, and ERV. A typical VC is 4,800 mL.
Inspiratory capacity (IC): The total amount of air that can be inhaled after a normal exhalation. This is calculated by adding the TV and IRV. A typical IC is 3,600 mL.
Functional residual volume (FRV): The amount of air remaining in the lungs after a normal exhalation. This is calculated by adding the ERV and RV. A typical FRV is 2,400 mL.
