More than 30 years after its first description, mortality associated with the acute respiratory distress syndrome (ARDS) is still great, with reported rates between 30 and 60%.80 The range in mortality is partly because of the loose definition6 of both ARDS and acute lung injury (ALI), based on bilateral lung infiltrates on X-ray, a left ventricular filling pressure <18 mm Hg and a PaO2/FIO2 of <300 mm Hg (ALI) or <200 mm Hg (ARDS). No factors relating to lung mechanics are used in these definitions. Use of PEEP can easily move the patient from ARDS to ALI or even out of the definition completely. The vagueness of the definition is also indicated when mortality is the same in ALI and ARDS, not related to ventilator settings.49 50 However, Amato and colleagues2 showed that a protective form of ventilation, in contrast to normal ventilator treatment, reduced mortality from 71 to 38%
