Fig. 3. Individual and average ( horizontal bar ) values of tidal volume (VT), plateau pressure (PPLAT) positive end expiratory pressure (PEEP), and arterial to inspired O2fraction ration (Pao2/Fio2) during acute respiratory distress syndrome network ( “ARDSNet” ) strategy after lowering VTand before initiating carbon dioxide removal (baseline), and 60–90 min (T1.5), 24 h (T24), 48 h (T48), and 72 (T72) after initiation of carbon dioxide removal. * P < 0.01 versus ARDSNet strategy.
