    INPUT: In comparison to prior radiograph , there has been no interval change substantial left lung volume loss and associative leftward mediastinal shift . The right lung is fairly hyperexpanded and crosses the thoracic midline . Unchanged atelectatic changes in the right lung . The cardiomediastinal silhouette is not well assessed due to the significant mediastinal shift . There is likely a small right pleural effusion . The ET tube now terminates approximately 6 cm above the carina . The NG tube terminates within the stomach . The left PICC line likely terminates in the cavoatrial junction however it is difficult to assess considering the degree of mediastinal shift . Stable mild thoracic scoliosis .
    OUTPUT:
    
The ET tube terminates 6 cm above the carina . Otherwise unchanged study .
