Tidal Volume

The volume of air inhaled or exhaled in a normal breath during resting conditions.

Static Volume

A measurement in fluid mechanics that refers to the volume of a fluid at rest.

Inspiratory Reserve Volume

The additional volume of air that can be inhaled into the lungs beyond the normal tidal volume inhalation.
