Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a right internal jugular central venous catheter ending in the right atrium . The ET tube and NG tube are in unchanged satisfactory position . No pneumothorax is detected . Lung volumes remain low with unchanged extensive left lung opacity , which obscures the cardiac silhouette . The presence of air bronchograms suggest left lower lobe collapse and / or consolidation . A small left effusion would be difficult to exclude . Again seen is some patchy opacity at the right cardiophrenic region , though the right lung remains otherwise grossly clear .
    OUTPUT:
    
Lines and tubes as described . Note is made that the right IJ line overlies the right atrium , rather than the SVC itself . No pneumothorax detected .
