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.
Tidal volume is a number that describes how much air a patient moves in and out of his lungs, both lungs together at the same time, with each breath, either in, or out, measured in cc of air. Bigger (within the normal range of roughly 300-450cc) is generally better.
