    INPUT: Frontal supine view of the chest was obtained . Endotracheal tube terminates 5 .4 cm above the carina , similar to prior . OG tube terminates below the diaphragm . Left pleural tube is in similar position to prior . There has been interval improvement in right upper lung opacity , likely representing improved aeration of the right upper lobe with overall improved right lung volumes . Opacity at the bilateral bases , right greater than left , may represent asymmetric edema . No pneumothorax is seen . The cardiomediastinal silhouette is stable .
    OUTPUT:
    
Improved aeration of the right upper lobe . Bibasilar vague opacities , right greater than left , is compatible with asymmetric edema .
