Methods are provided for protecting against ventilation-induced lung injury by promoting equitable liquid distribution in a lung with alveolar flooding, in which flooded and aerated alveoli are interspersed. Since ventilation injuriously over-expands aerated alveoli adjacent to flooded alveoli and a pressure barrier is responsible for trapping liquid in discrete alveoli, the present invention provides various means for overcoming the pressure barrier to, in turn, promote equitable redistribution of flooding liquid amongst alveoli, reduce the number of aerated alveoli located adjacent to flooded alveoli and reduce ventilation injury of the lung. These means of overcoming the pressure barrier include: (i) use of accelerated deflation during mechanical ventilation and ii) high frequency (>50 Hz) vibration of the lung.
