Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient remains intubated . The endotracheal tube terminates nearly 8 cm above the carina compared to about 5 .5 cm before . Bilateral internal jugular venous catheters appear unchanged . An orogastric tube also enters the stomach . There is increased bilateral perihilar opacification but with some improvement in aeration of the right lower lung . This appearance suggests moderate vascular congestion , perhaps slightly increased , with similar probably moderate layering bilateral pleural effusions , within the limitations of technique . Retrocardiac opacity is not as well imaged since the lower chest is partly excluded but is probably unchanged .
    OUTPUT:
    
High endotracheal tube ; advancing the tube by 3 - 4 cm is suggested . Improved aeration of the right lower lung , otherwise not significant change .
