    INPUT: Supine portable AP view of the chest is provided . The endotracheal tube is seen with its tip located approximately 1 .5 cm above the carina . NG tube courses inferiorly with its tip not visualized . Lung volumes are low . VP shunt catheter courses over the right hemithorax . There is relative hilar prominence , likely reflecting crowded bronchovasculature . The possibility of scattered atelectasis and aspiration is difficult to exclude . No large effusion or pneumothorax seen . Bony structures appear grossly intact .
    OUTPUT:
    
ET tube positioned low with tip 1 .5 cm above carina . Recommend retraction by at least 1 cm for more optimal placement . NG tube positioned appropriately . Lung volumes are low with bronchovascular crowding and possible atelectasis / aspiration .
