Vital capacity (VC): the volume change of the lung between a full inspiration and a maximal expiration. 1. The maneuver is performed rather slowly. The vital capacity is assessed during an inspiratory maneuver. Starting from end-tidal volume the subject expires maximally and subsequently makes a full inspiration.
A. Total Lung Capacity (TLC) - the volume of air in the lungs after a maximal inspiratory effort. Determined by the strength of contraction of the inspiratory muscles in opposition to the inward elastic recoil of the lungs and chest wall. About 6 liters in a healthy 70 kg adult.
