    INPUT: Portable upright chest radiograph demonstrates an endotracheal tube with its tip at the level of the clavicular heads . An NG tube passes through the stomach , and a right subclavian central venous catheter tip is at the cavoatrial junction . There is an interval decrease in lung volumes ; small bilateral pleural effusions and bibasilar atelectasis is mild and increased . The cardiac silhouette is enlarged and unchanged . The mediastinal contours are little changed . Pulmonary vasculature is normal and improved .
    OUTPUT:
    
1 . Endotracheal tube projects just beyond the thoracic inlet , and might be advanced 1 .5 cm for more optimal seating . 2 . Interval decrease in lung volumes with increase in bibasilar atelectasis and small bilateral pleural effusions , although edema has improved .
