    INPUT: Right internal jugular central venous catheter tip lies within the proximal right atrium . No pneumothorax is identified . Endotracheal and enteric tubes remain in similar positions . Lung volumes remain low with crowding of the bronchovascular structures and probable mild pulmonary vascular congestion . Patchy opacities in the lung bases appear slightly worse in the interval , and again may reflect areas of atelectasis . No pleural effusion is identified .
    OUTPUT:
    
Right internal jugular central venous catheter tip in the proximal right atrium . No pneumothorax . Probable mild pulmonary vascular congestion and slight interval worsening of bibasilar atelectasis .
