Answer

The traditional ventilatory strategy of delivering high tidal volumes leads to high end-inspiratory alveolar pressures (ie, plateau pressure). Many investigators now believe that repeated cycles of opening and collapsing of inflamed and atelectatic alveoli are detrimental to the lung. Failure to maintain a certain minimum alveolar volume may further accentuate the lung damage. Furthermore, transalveolar pressure (reflected by plateau pressure) exceeding 25-30 cm water is considered to be an important risk factor for stretch injury to the lungs.
