Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient remains intubated . Endotracheal tube terminates fairly close to the carina , within about 1 .5 cm and it may be appropriate to retract the tube by about 1 .5 cm . Right internal jugular and left subclavian venous catheters are present . Bilateral abdominal drains are still present as well . The left lung base remains similarly opacified , with volume loass and including suggestion of a layering pleural effusion . The retrocardiac area is typical for atelectasis of the left lower lobe although pneumonia can not be excluded at this site . There has been no definite change .
    OUTPUT:
    
Low - lying endotracheal tube ; retraction by 1 - 2 cm may be appropriate . Similar opacification of the left lung base with pleural effusion .
