FINDINGS:
AP portable upright view of the chest.   The endotracheal tube is seen with
 its tip residing 2.3 cm above the carina.  The endogastric tube descends into
 the left upper quadrant.  A left chest wall pacer device is noted with leads
 extending to the region of the right atrium and right ventricle.  Retrocardiac
 vague linear densities are noted which could reflect atelectasis though
 difficult to exclude a component of aspiration.  Otherwise the lungs appear
 grossly clear.  No definite signs of effusion or pneumothorax.  No signs of
 congestion or edema.  The cardiomediastinal silhouette appears within normal
 limits allowing for technique.  Bony structures appear intact.

IMPRESSION:
Tubes positioned appropriately.  Minimal linear opacity in left lower lung
 likely atelectasis, difficult to exclude a component of aspiration.
