    INPUT: Since the prior chest radiograph performed 1 day earlier , there has been interval placement of an endotracheal tube which terminates 3 .9 cm above the carina . A transesophageal catheter extends to at least the body of the stomach , although the tip is not visualized . There is at least moderate gaseous distension of the stomach . Pulmonary edema is mild , although worse from the prior study performed earlier on the same date . Dense left retrocardiac opacity most likely represents atelectasis . No sizable pleural effusion or pneumothorax . Cervical spine fusion hardware is incidentally noted .
    OUTPUT:
    
1 . Appropriate positioning of the new endotracheal tube , approximately 3 .9 cm above the carina . 2 . Slightly worsening pulmonary edema .
