FINDINGS:
In comparison with the study of , there has been placement of a
 right IJ catheter that extends to the mid portion of the SVC.  Other
 monitoring and support devices are essentially unchanged.  Retrocardiac
 opacification is again consistent with volume loss in the left lower lobe. 
 Mild atelectatic changes are seen at the right base.
 
 There is some indistinctness of pulmonary vessels, suggesting some elevation
 of pulmonary venous pressure.
