tidal volume
Quick Summary
Tidal volume refers to the amount of air inhaled or exhaled during a normal, resting breath. It is a key measurement in pulmonary function tests used to assess lung health and diagnose respiratory diseases.12
Lung capacity encompasses various measurements of how much air the lungs can hold and move. These include:
* Residual volume (RV): Air left in the lungs after maximum exhalation.1
* Functional residual capacity (FRC): Air in the lungs at the end of a quiet exhalation.1
* Vital capacity (VC): The maximum amount of air that can be exhaled after a deep inhalation.1
* Total lung capacity (TLC): The total volume of air in the lungs after maximum inhalation.1
Infants have a significantly smaller tidal volume and breathe more frequently than adults.2

Certain portions of the airways (trachea, bronchi, bronchioles) do not participate in respiratory exchange, and the gas that fills these structures occupies an anatomical dead space of about 150 millilitres in volume. Of a tidal volume of 500 millilitres, only 350 millilitres ventilate…
