Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are unchanged and within normal limits . The patient is intubated , the endotracheal tube terminates 3 cm above the level of the carina . A Dobhoff tube terminates in the stomach . A right internal jugular catheter terminates in the mid SVC . A right - sided PICC terminates in the right brachiocephalic vein . These are unchanged in appearance when compared to the prior studies . There is increased opacity at the left lung base , likely reflecting atelectasis but superimposed infection can not be excluded . No other areas concerning for infection are identified . There is likely a small left pleural effusion . No pneumothorax seen .
    OUTPUT:
    
Left lower lobe atelectasis versus consolidation have progressed when compared to the prior study .
