CVCs are catheters placed centrally, with the tip of the catheter located in the lower third of the superior vena cava (SVC). CVCs can remain in situ for less than 30 days and are used mostly in acute/emergent settings to administer bloodstream medication or fluids, obtain blood tests, and measure central venous pressure. CVCs are most commonly inserted in an X-ray room by a radiologists, specially-trained nurses, and technologists.
