    INPUT: Semi supine portable AP chest radiograph demonstrates interval retraction of an endotracheal tube which appears to terminate 3 .8 cm above the level of the carina . An enteric tube descends the thorax in uncomplicated course , its tip below the level of the left hemidiaphragm incompletely imaged . Lung volumes are low with associated atelectasis . Cardiomediastinal and hilar contours are stable . Central vascular crowding is likely sequela of low lung volumes . There is no pneumothorax . There is no large pleural effusion . Blunting of the left costophrenic angle may reflect pleural thickening . There is no air under the right hemidiaphragm .
    OUTPUT:
    
Interval retraction of endotracheal tube now appropriately positioned . Low lung volumes .
