Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: ET tube approximately 6 .8 cm above the carina . NG tube tip over stomach . Enteric type tube extending beneath diaphragm , off film . Right IJ central line over proximal SVC . Left IJ central line near confluence of left innominate and right subclavian vessels . No pneumothorax is detected . Cardiomediastinal silhouette is probably unchanged . Hazy density at both lung bases could reflect presence of small layering effusions . There is underlying bibasilar collapse and / or consolidation . There is upper zone redistribution and mild diffuse vascular blurring consistent with CHF . This may be very slightly improved compared with the prior film as the confluent opacity in left mid zone is less apparent .
    OUTPUT:
    
Findings similar to the prior study from ___ at 04 :02 a .m . . Possible slight interval improvement in CHF findings .
