Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The ET tube terminates at the level of the upper clavicles , but could be advanced by 2 - 3 cm for more optimal ventilation . A right IJ central venous catheter terminates in the upper SVC . A nasogastric tube coils in the stomach . There has been marked improved aeration of the lung long , however substantial airspace opacification of the entire right lung and left perihilar location are unchanged . There is no pneumothorax . New moderate right pleural effusion is unchanged . The heart and mediastinum are within normal limits despite the projection .
    OUTPUT:
    
Improved aeration of the left lung as compared to the study of 1 day prior . High - riding ET tube could be advanced by 2 - 3 cm from more optimal aeration . Persistent extensive right lung edema or hemorrhage may either be due to a continuation of the same process or new aspiration . Stable moderate right pleural effusion .
