FINDINGS:
As compared to the previous radiograph, the lung volumes have
 increased.  There is a minimal atelectasis at the left lung bases, potentially
 accompanied by a minimal pleural effusion, reflected by blunting of the left
 costophrenic sinus.  Otherwise, the radiograph is unchanged.  No overt
 pulmonary edema.  No pneumonia.  The nasogastric tube is in constant position.
