Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube and right upper central venous line are in unchanged position . An extremely large hiatal hernia continues to cause rightward shift of the mediastinum . Tip of the nasoenteric catheter is above the left hemidiaphragm within the hernia sac . Apparent widening of the mediastinum is similar to prior and likely due to a combination of mediastinal shift and patient rotation . Opacity within the right medial lung base has slightly progressed and is likely due to progressive middle lobe atelectasis . Increasing right pleural effusion is likely , now moderate . A small left pleural effusion persists . Left lower lobe atelectasis is also likely . Upper lungs remain clear .
    OUTPUT:
    
1 . Increasing basilar atelectasis and effusions , now moderate . No overt interstitial edema . 2 . Mediastinal widening , likely due to rotation and shift , unchanged . 3 . Unchanged large hiatal hernia
