    INPUT: There has been interval placement of a left IJ central venous catheter which terminates in the superior cavoatrial junction . The pre-existing right IJ terminates in the right atrium . The ET tube is correctly positioned 4 .7 cm above the carina . An enteric tube is partially visualized with the tip coursing out of the field of view of this exam . There has been interval improvement in the atelectasis at the left lung base as well as bilateral perihilar opacities which probably reflects a combination of pulmonary edema and resolving atelectasis . The cardiac silhouette is stable . There is no pleural effusion or pneumothorax . Included upper abdomen is unremarkable .
    OUTPUT:
