Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient has been extubated and the orogastric tube has been removed . Right IJ central line again extends to the mid SVC . Widespread pulmonary opacities appear slightly more confluent at the right lung base , though there is slightly improved aeration in the retrocardiac region . The appearance at the right base may reflect atelectasis in the setting of extubation . Presumed effusions are again not readily apparent . There is no pneumothorax . Hilar and cardiomediastinal contours are unchanged . There is no free air in the upper abdomen .
    OUTPUT:
    
Persistent widespread pulmonary opacities , slightly increased at the right base possibly reflecting interval extubation .
