Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube tip is approximately 4 .6 cm above the carina . NG tube courses below the diaphragm and out of view ; the side port and tip are not seen . The right PA catheter tip appears to be in the left main pulmonary artery , similar to the recent final chest fluoro image . Right jugular venous line tip appears to be near the SVC / RA junction , although somewhat difficult to determine due to the PA catheter running through it . Low lung volumes cause bronchovascular crowding and accentuation of the cardiac silhouette , similar to prior . Moderate pulmonary vascular congestion and mild edema are similar to prior . Moderate left and trace right pleural effusions are similar to prior . There is no pneumothorax . Sternal wires are intact . No free air below the right hemidiaphragm is seen .
    OUTPUT:
    
Interval placement of an NG tube and exchange of a right jugular line with a PA catheter placed through it , as seen on recent chest fluoro .
