Airway (P ao ) and esophageal (P eso ) pressures in a patient with pneumonia and ARDS under volume-controlled ventilation with Vt 6 (left) and Vt 12 (right) mL/kg IBW and similar PEEP. Transpulmonary driving pressure (shown as gray bars) is the difference between airway driving pressure (DP, solid arrows) and esophageal driving pressure (DP eso , dotted arrows). Both airway DP and transpulmonary DP increased when using a higher Vt. Modified from [11]
