tidal volume (TV)

the amount of air you move into or out of your lungs during a single respiratory cycle under resting conditions

expiratory reserve volume (ERV)

the amount of air that you can voluntarily expel after you complete a normal, quiet respiratory cycle

residual volume (RV)

the amount of air that remains in your lungs even after a maximal exhalation

inspiratory reserve volume (IRV)

the amount of air that you can take in over and above the tidal volume

tidal volume (TV)

the amount of air inhaled and exhaled during one normal breath

inspiratory reserve volume (IRV)

maximum amount of air that can be inhaled after a normal inhalation

expiratory reserve volume (ERV)

maximum amount of air that can be exhaled after a normal exhalation

residual volume (RV)

amount of air that remains in the lungs after a maximal exhalation

tidal volume (TV)

equal to IC-IRV

residual volume (RV)

equal FRC-ERV

inspiratory reserve volume (IRV)

equal IC-TV

inspiratory capacity (IC)

is the maximum amount of air that you can draw into your lungs after you have completed a quiet respiratory cycle.

inspiratory capacity (IC)

the sum of the tidal volume and the inspiratory reserve volume

functional residual capacity (FRC)

the amount of air remaining in your lungs after you have completed a quiet respiratory cycle

functional residual capacity (FRC)

the sum of the expiratory reserve volume and the residual volume

vital capacity

the maximum amount of air that you can move into or out of your lungs in a single respiratory cycle

vital capacity

the sum of the expiratory reserve volume, the tidal volume, and the inspiratory reserve volume

total lung capacity

the total volume of your lung

total lung capacity

the sum of the vital capacity and the residual volume

inspiratory capacity (IC)

equal TV+IRV

functional residual capacity (FRC)

volume of air remaining in lung after normal exhalation

vital capacity

maximum amount of air that you can be exhaled after a normal inhalation

total lung capacity

equal TV+IRV+ERV+RV

inspiratory capacity (IC)

TV+IRV

functional residual capacity (FRC)

RV+ERV

vital capacity

maximum amount of air that you can be expelled after a maximal inhalation

vital capacity

equal IRV+TV+ERV
