    INPUT: Single portable supine frontal chest radiograph demonstrates interval placement of endotracheal tube 2 .7 cm above the level of the carina . An enteric feeding tube is seen coursing mid line with tip out of field of view . Persistently hypoinflated lungs with vascular crowding and right lower lobe atelectasis . No pneumothorax . Persistent small to moderate left pleural effusion with retrocardiac opacity and mild cardiomegaly which is partially obscured by left pleural effusion . Aortic arch calcifications noted . Mediastinal contour and hila are otherwise unremarkable . Chronic deformity of the left clavicle again noted .
    OUTPUT:
