<qa>  What was the maximum end-inspiratory plateau pressure?The few interventions that have been shown to reduce the high mortality in these patients have targeted ventilator-induced lung injury VILI. A landmark trial by the ARDSNet trials group found that ventilating patients with acute hypoxaemic respiratory failure secondary to ARDS with a lung protective strategy aiming for a reduced tidal volume of 6mlkg predicted body weight PBW and a maximum end-inspiratory plateau pressure Pplat 30cmH2O decreased mortality from 40 in the conventional arm treated with tidal volume less than 12mlkg PBW to 31.
