Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle. Lung volumes are directly measured. Lung capacities are inferred from lung volumes.
This can be calculated by the addition of tidal volume and the IRV. Vital Capacity (VC) is the maximum volume of air that can be exhaled following a deep inspiration. This is the total of IRV + TV + ERV. Functional Residual Capacity (FRC) is the volume of air that remains in the lungs during quite breathing.
