Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right IJ sheath is present . The tip lies near the point of confluence with the subclavian vessel . Tubing overlies the upper mediastinum in the midline . If this is an ET tube , it lies relatively low , only 1 cm above the carina . If it is an NG tube , then it has not passed beyond the mid esophagus . There are low inspiratory volumes . There is probable mild vascular plethora , though this is likely accentuated by low inspiratory volumes . Minimal subsegmental atelectasis at the bases . No focal infiltrate , frank consolidation or gross effusion . No free air seen beneath the diaphragm . R Rounded densities overlying the cardiac silhouette adjacent to the descending aorta may represent vessels seen on - end .
    OUTPUT:
    
Tubing which overlies the mid mediastinum in the midline . Clinical correlation is requested . If this is an ET tube , it lies relatively low , only 1 cm above the carina . If it is an NG tube , then it has not passed beyond the mid esophagus . Low inspiratory volumes . Possible mild vascular plethora , though this is likely accentuated by low lung volumes . No focal infiltrate or gross effusion .
