Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right internal jugular catheter is present with the tip in the upper SVC . A left - sided chest tube is in unchanged position . Sternal wires are intact . Since the prior exam , the endotracheal tube and nasogastric tube have been removed . The lung volumes are lower , accentuating the bronchovascular structures and pleural effusions . Small - to - moderate bilateral pleural effusions are likely just slightly increased in szie . There is associated atelectasis . The apices of lungs are clear . The mediastinal contours are unchanged , with an expected postoperative appearance . The cardiac size is difficult to evaluate given the adjacent effusions .
    OUTPUT:
    
Low lung volumes after extubation . Slight interval increase in size of bilateral small - to - moderate pleural effusions .
