    INPUT: Compared with the prior film , the chest tube is been removed . There is a new small left pleural effusion , with underlying collapse and / or consolidation . Note is made of trace pneumomediastinal air , which has decreased compared with the prior film . No pneumothorax is detected . There are lower inspiratory volumes . Allowing for this , no definite change in the cardiomediastinal silhouette . Atelectasis at the right base . Mild vascular plethora is likely accentuated by low lung volumes . Sternotomy wires again noted . Right IJ central line tip overlies the mid / distal SVC .
    OUTPUT:
    
1 . Interval removal of chest tube . New small left pleural effusion with underlying collapse and / or consolidation . 2 . Interval decrease in size of small amount of pneumomediastinum air .
