    INPUT: Endotracheal tube tip terminates approximately 6 .3 cm from the carina . An enteric tube tip is within the stomach . Low lung volumes are present . Heart size is top normal . Mediastinal and hilar contours are unremarkable . Crowding of bronchovascular structures is present without pulmonary edema . Patchy opacities within the lung bases may reflect atelectasis in the setting of low lung volumes . No pleural effusion or pneumothorax is identified . No acute osseous abnormality is detected .
    OUTPUT:
    
1 . Endotracheal and enteric tubes in standard positions . 2 . Low lung volumes with patchy bibasilar airspace opacities , likely atelectasis .
