FINDINGS:
ET tube is in adequate position, terminating 4.0 cm from the carina.  There is
 opacity in the medial right lung base, which could represent atelectasis but
 cannot exclude aspiration or pneumonia in the right clinical setting.  The
 lungs are otherwise clear.  There is no pleural effusion or pneumothorax.  The
 cardiomediastinal silhouette is top normal in size.
