Document Summary
Tidal volume amount of air inhaled or exhaled during asingle respiratory. Lung volumes cycle: average tidal volume for adults: 500 cc or 500ml (0. 5l, activity demands larger tidal volume to reflect greater oxygen expenditure, can increase to match the oxygen volume of your body. Inspiratory reserve volume (irv: amount of additional air that can be forcibly inhaled after the inspiration of normal tidal volume, around 3x that of tidal volume, over and above a normal inhalation. Expiratory reserve volume (erv) or resting lung volume (rlv: amount of additional air that can be forcibly exhaled after exhalation of normal tidal volume, over and above a normal exhalation. Residual volume (rv: quantity of air left over in lungs and airways after maximum forcible exhalation, cannot be forcibly expelled from lungs, remains after death, crackly lungs in cadavers, approx 1,000 cc. A lung capacity is the sum of two or more lung volumes.
