    INPUT: The endotracheal tube ends 6 cm above the carina . The enteric tube has been advanced and ends in the stomach . The lung volumes remain low . The heart size is slightly enlarged . IN THE SETTING OF RIGHTWARD MEDIASTINAL SHIFT , RIGHT lower lung opacity and obscuration of the right hemidiaphragm REFLECT DEVELOPING RIGHT LOWER LOBE ATELECTASIS . WHETHER RIGHT PLEURAL EFFUSION IS PRESENT IS RADIOGRAPHICALLY INDETERMINATE . No large pneumothorax is identified . LOW RIB FRACTURES ARE DEMONSTRATED BY TORSO CTA PERFORMED SUBSEQUENTLY AND AVAILABLE THE TIME OF FINAL REVIEW OF THIS STUDY .
    OUTPUT:
    
1 . The endotracheal tube ends 6 cm above the carina . The tube could be advanced 2 cm for optimal positioning . 2 . DEVELOPING RIGHT LOWER LOBE ATELECTASIS . POSSIBLE RIGHT PLEURAL EFFUSION . NO PNEUMOTHORAX .
