    INPUT: The NG tube tip is in the proximal stomach . Left - sided PICC line tip is at the cavoatrial junction . Lung volumes are low with volume loss at the bases . There is hazy increased opacity in the retrocardiac region that could represent an infiltrate . This is slightly more prominent than on the prior studies . In addition the right hilum appears very prominent but this is felt to be projectional there is a small right lower lobe opacity that could be due to volume loss versus early infiltrate
    OUTPUT:
    
Slight worse appearance to the lower lungs . Is unclear if this is all due to volume loss surface there is an underlying infectious infiltrate .
