    INPUT: A right PICC is similar in configuration with the tip terminating in the proximal right atrium , which should be retracted 2 .5 - 3 cm to place in the low SVC . The course of the line is unremarkable . The inspiratory lung volumes are decreased from the most recent prior study . No large pleural effusion or pneumothorax is detected . There is no overt pulmonary edema . The cardiomediastinal silhouette is exaggerated due to AP technique and low lung volumes , but likely remains within normal limits and stable . There is partial calcification of the aortic knob . A healed right posterior rib fracture is redemonstrated .
    OUTPUT:
    
Right PICC with tip in the proximal right atrium should be retracted 2 .5 - 3 cm to place in low SVC . Otherwise , stable appearance of the chest from ___ .
