    INPUT: A right internal jugular central venous catheter ends in the mid SVC . A Dobbhoff tube is seen ending within the upper portion of the stomach , although the proximal portion of its floppy end is in the distal esophagus . Previously , the entirety of the Dobbhoff tube ended within the lower esophagus . Lung volumes remain very low , although slightly improved compared to the prior study from ___ . There is minimal bilateral lower lobe atelectasis . Apparent enlargement of the cardiac silhouette is likely at least partially attributable to low lung volumes . The mediastinal contours are unchanged . There are no definite pleural effusions . No pneumothorax is seen .
    OUTPUT:
    
1 . Dobbhoff tube has been slightly advanced , although a portion of its floppy tip continues to end in the distal esophagus . Recommend advancing . 2 .
