Lung Volumes Tell Us How Much Air the Lungs Move and How Well They Work

Lung volumes are the different amounts of air the lungs hold or move during breathing.
They show how well the lungs are working and help doctors monitor respiratory health.

The Main Lung Volumes and Capacities

Tidal volume (TV): the air breathed in or out in one normal, resting breath, about 500 mL.
Inspiratory reserve volume (IRV): the extra air you can breathe in after a normal breath, about 1,900–3,100 mL.
Expiratory reserve volume (ERV): the extra air you can breathe out after a normal breath, about 700–1,200 mL.
Vital capacity (VC): the most air you can breathe out after the deepest possible breath in, about 3,000–5,000 mL.
Residual volume: the air that stays in the lungs even after the hardest breath out, so they never fully empty.
Total lung capacity: the vital capacity plus the residual volume, the full amount the lungs can hold.

Note

Vital capacity is the tidal volume plus both reserve volumes.
VC = TV + IRV + ERV.
