    INPUT: There are low lung volumes , which results in bronchovascular crowding . Increased opacity at the bilateral bases is noted . Mild pulmonary vascular congestion . Cardiomediastinal and hilar contours are unchanged . A left - sided internal jugular central venous line ends in the upper right atrium . No pneumothorax .
    OUTPUT:
    
1 . Left internal jugular central venous line terminates in the upper right atrium . 2 . No pneumothorax . 3 . Opacity at the right base may represent aspiration or pneumonia in the appropriate clinical setting . Asymmetrical edema is an additional consideration in the setting of mild pulmonary vascular congestion .
