Nasogastric tube is noted which terminates below the left hemidiaphragm , off the inferior borders of the film , . Lung volumes are low . Heart size appears moderately enlarged . Widening of the superior mediastinum is likely due to supine technique and low lung volumes . There is crowding of the bronchovascular structures . No overt pulmonary edema is noted . Retrocardiac hazy opacity may reflect atelectasis . A small left pleural effusion may be present . No pneumothorax is identified .
    OUTPUT:
    
Standard positioning of the endotracheal tube and nasogastric tube . Low lung volumes . Hazy retrocardiac opacity may reflect atelectasis . Possible small left pleural effusion .
