Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube lies approximately 5 .4 cm above the carina , with its tip at the level of the mid clavicular heads , similar to the prior film . An NG tube is present , tip extending beneath diaphragm , curling in the expected location of the gastric fundus , also similar to prior . An intra-aortic balloon pump is present . It appears to lie more distal in the descending aorta than on the prior film . Although the aortic knob is not well delineated , the radiopaque tip of the inferior bone pump appears to lie slightly inferior to the expected site of the inferior edge of aortic knob , nominal in alignment . An inferior approach catheter is present . This likely represents a Swan - Ganz catheter , with tip superimposed over the main pulmonary artery . A large caliber tube or catheter lies immediately to the right of midline , extending from inferior to overlie the upper / mid thoracic spine . Again seen are opacities in both lungs , most pronounced in the upper lobes , where either fluid or pleural parenchymal scarring may also be present . On the left , there is dense opacity throughout the upper and mid zones . On the right , there are opacities in a similar distribution , but these do not appear is density appearance . Compared to a semi supine film from very early the same - day ( just after midnight ) , there appears to been some leftward shift of the mediastinum , raising the question of volume loss in the left lung . The left hemidiaphragm canal appears tented and the diaphragm is also partially obscured medially . This appearance is similar to the film from 03 :42 a .m . .
    OUTPUT:
    
1 . ET tube tip at level of mid clavicular heads , approximately 5 .4 cm above the carina , essentially unchanged . 2 . Interval distal retraction of the radiopaque portion of the intra-aortic balloon pump . I suspect that the tip now lies very slightly below the inferior edge of the aortic knob , nominal in position . 3 . Findings suggestive of left - sided volume loss , with leftward shift of mediastinum . 4 . Opacities in both lungs , within upper zone predominance and relative sparing of the bases . This is similar to multiple prior films , though the difference in degree of opacity --___ much denser on the left -- has progressed compared with the initial film . The reason for this is uncertain . While it could be technical , it may also be accentuated by atelectasis / volume loss . 5 . Increased retrocardiac density , consistent with left lower lobe collapse and / or consolidation , has also progressed since the initial film . This may be accentuated by supine positioning .
