WebTidal Volume. Tidal volume is a measure of the amount of air a person inhales during a normal breath. Traditional preset tidal volumes higher than 10 ml/kg have been proved to be associated with increased risk of pulmonary barotrauma and should be avoided. High tidal volumes also decrease venous return and reduce cardiac output.
