Abstract

The adult respiratory distress syndrome (ARDS) is characterized by progressive respiratory distress, hypoxemia refractory to oxygen breathing and diffuse radiologic lung consolidation. To evaluate the prognostic parameter of ARDS, clinical review, serial measurement of arter ial blood gases and serial evaluation of chest X-ray were performed at Medical Intensive Care Unit. The ratio of arterial oxygen tension to alveolar oxygen tension(Pa0₂/P_A0₂) and that of arterial oxygen tension to inspired oxygen fraction (Pa0₂/FiO₂ ) in patients of recovered ARDS group was significantly higher than that in patients of non-recovered group from the 1st day to the 7th day on ventilator but the radiologic scores in patients of recorerved ARDS group tended to show lower value than that in patients of non-recovered ARDS group, which was not stastically significant from 0 day to the 6-th day on ventilator. These results suggest that the ratio of Pa0₂/P_A0₂ and Pa0₂/FiO₂ is valuable in predicting the prognosis of ARDS, but the Radiologic Scores is not predictive.
