    INPUT: Lung volumes are low . Small - to - moderate bilateral pleural effusions and severe bibasilar atelectasis persist . Upper lobe vascular congestion could be physiologic given severe atelectasis and small pleural effusions . Heart and mediastinal contours are unchanged . Enteric catheter courses below the diaphragm with tip projecting over the left upper quadrant , likely in the distal duodenum . Right PICC appears similarly positioned . No pneumothorax is detected .
    OUTPUT:
