Larger multi-center epidemiological studies are necessary to determine whether these multiple conditions are truly independent predictors of mortality in ARDS. Since most ARDS patients do not die of persistent respiratory failure, it might not be surprising that initial indexes of oxygenation and ventilation, including the ratio and the lung injury score, do not predict outcome (79). The ARDSnet trial reported that the patients with improved survival due to low tidal volume ventilation actually had a worse ratio when compared to high tidal volume group.
Definitions and clinical risk factors 17 D. Future Directions Even after three consensus conferences and multiple studies, several issues still remain concerning the present diagnostic criteria for ARDS, including the heterogeneity of the patient population, the absence of a diagnostically accurate biochemical marker, and the lack of a reliable noninvasive measure of alveolar-capillary injury or permeability. Presently, ARDS can occur in a heterogeneous group of patients who develop common physiological and radiographic abnormalities.
