    INPUT: A portable frontal chest radiograph again demonstrates bilateral chest tubes , a nasogastric tube , and right PICC , all of which are unchanged in position . The left central catheter has been exchanged . Increased right lower lung linear opacities likely represent increased atelectasis . There is improved aeration of the left lower lobe , but increased lingular atelectasis . A small to moderate loculated left pleural effusion is persistent , and there is a small right pleural effusion which is new or slightly increased . There is no pneumothorax .
    OUTPUT:
    
1 . Increased right base and lingular atelectasis , with improved aeration of the left lower lobe . 2 . Persistent loculated small to moderate left pleural effusion , and new or slightly increased small right pleural effusion .
