    INPUT: Supine portable AP view of the chest provided . Tracheostomy tube , right upper extremity PICC line and NG tubes are again seen . The NG tube appears to descend into the left upper abdomen , though the tip is poorly visualized . There is a new left IJ central venous catheter with its tip at the expected level of the left brachiocephalic vein . There is increasing opacity within both lungs , though this could , in part , reflect underpenetrated technique . The heart remains enlarged . No pneumothorax is seen .
    OUTPUT:
    
1 . Left external jugular catheter tip in the region of the left brachiocephalic vein . 2 . Increasing pulmonary airspace opacity likely represents worsening edema .
