Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube ends at 4 cm from carina . The NG tube ends the in proximal gastric cavity , and can be advanced at least 5 cm . As compared to yesterday , the lung volume is largely increased with improvement of upper and mid lung opacification , likely for reduced pulmonary edema . The reduction of heart size is a sign of improved cardica function . Persist linear opacity at the lung bases , especially on the right , likely for atelectasis . Small pleural effusion on the right base . There is no pneumothorax .
    OUTPUT:
    
Improved lung ventilation for reduced pulmonary edema , persist lung base atelectasis , minimal to the left , small to the right with small right pleural effusion . NG tube should be pushed down 5 cm .
