Fig. 6. Distinguishing ARDS on radiography.

Fig. 6

Similarities in the chest radiographs from a patient with acute respiratory distress syndrome (ARDS) from influenza pneumonia (panel a) and a patient with pulmonary oedema due to cardiac failure (panel b) reflect the difficulty in identifying ARDS. In both cases, diffuse bilateral parenchymal opacities are consistent with alveolar filling. The cardiac silhouette (panel b) is slightly more globular, consistent with heart failure; however, this feature is not reliable for distinguishing ARDS from cardiogenic pulmonary oedema.
