    INPUT: Since prior exam , the endotracheal tube , enteric tube , Swan - Ganz catheter , and bilateral chest tubes have been removed . There is no pneumothorax . Since the prior exam , the lung volumes are lower , accentuating by the bronchovascular structures . Allowing for the changes in lung volume , mild pulmonary edema is unchanged . Small bilateral pleural effusions appear grossly stable . The cardiomediastinal silhouette has an expected postoperative appearance . Sternal wires are intact .
    OUTPUT:
    
1 . Status post chest tube removal . No pneumothorax . 2 . Unchanged mild pulmonary edema and small bilateral pleural effusions .
