Transpulmonary pressure guided mechanical ventilation strategy
DeviceTidal volume is adjusted to achieve a target tidal volume of 6 mL/kg predicted body weight (PBW) while controlling end-inspiratory transpulmonary pressure ≤ 20 cmH₂O. PEEP is adjusted to maintain end-expiratory transpulmonary pressure between 0 and 2 cmH₂O.
In control group, PEEP was titrated using the low PEEP:FiO₂ table method.
