Observations of the adverse effects of barotrauma and volutrauma have led to recommendations of lower tidal volumes than in years past, when tidal volumes of 10-15 mL/kg were routinely used.

An initial TV of 5-8 mL/kg of ideal body weight is generally indicated, with the lowest values recommended in the presence of obstructive airway disease and ARDS. The goal is to adjust the TV so that plateau pressures are less than 35 cm water.
