Quizplus · Accepted Answer

Vital capacity is measured by having the patient take in a maximal breath and exhale fully through a spirometer. Vital lung capacity is the maximal volume of air exhaled from the point of maximal inspiration, and neuromuscular disorders such as multiple sclerosis may lead to a decreased vital capacity. Tidal volume is defined as the volume of air inhaled and exhaled with each breath. The volume of air in the lungs after a maximal inspiration is the total lung capacity. Inspiratory capacity is the maximal volume of air inhaled after normal expiration.
