Tidal volume
Tidal Volume
Tidal volume (TV), pronounced as /ˈtaɪdəl ˈvɒljuːm/, is the volume of air that is inhaled or exhaled from the lungs during normal breathing. The term originates from the Latin words 'tide' meaning 'time' and 'volume' meaning 'amount'.
Definition
Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle. It can be measured using a spirometer, which is a device that measures the volume of air inhaled and exhaled by the lungs. The average tidal volume is about 500 milliliters for men and 400 milliliters for women.
