Question Answer
Tidal volume (TV)Amount of air inhaled or exhaled with each breath under resting conditions.
Inspiratory reserve volume (IRV)Amount of air that can be forcefully inhaled after a normal tidal volume inspiration.
Expiratory reserve volume (ERV)Amount of air that can be forcefully exhaled after a normal tidal volume expiration.
Residual volume (RV)Amount of air remaining in the lungs after a forced expiration.
Total lung capacity (TLC)Max. amount of air contained in lungs after a max. inspiratory effort: (TV + IRV + ERV + RV)
Vital capacity (VC)Max. amount of air that can be expired after a max. inspiratory effort: (TV + IRV + ERV)
Inspiratory capacity (IC)Max. amount of air that can be inspired after a normal tidal volume expiration: (TV + IRV)
Functional residual capacity (FRC)Volume of air remaining in the lungs after a normal tidal volume expiration: (ERV + RV)
