    INPUT: A portable frontal chest radiograph again demonstrates a right PICC with the tip in the right atrium . For positioning in the low SVC , the PICC can be pulled back 5 cm . The tip of the endotracheal tube is approximately 3 .5 cm above the carina , and given that the patient 's chin is in a downward position , should be pulled back 1 .5 cm . The remainder of the exam is unchanged , demonstrating severe pulmonary edema .
    OUTPUT:
