Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube ends 3 cm above the carina . Tip of the Swan - Ganz catheter remains in the proximal right pulmonary artery . Right PICC line ends in the mid SVC . NG tube passes into the stomach and out of view . A left pacemaker with leads in the expected position of the right atrium and right ventricle is unchanged . Compared with most recent prior radiograph , lung volumes are lower and as a consequence , there is a general increase in lung density . In addition , there has been decrease in left upper lung opacity with increase in left lower lung opacity , which given the time course likely represents redistribution of pulmonary edema . Severe cardiomegaly is unchanged . No pneumothorax is present .
    OUTPUT:
    
Interval decreased opacity in left upper lung and increased opacity in left lower lung likely represent redistribution of pulmonary edema given the time course .
