Central venous catheter
AKA: " Central line, CVC "
A catheter that is placed in a large vein in the neck or shoulder area. The catheter is used for giving medications and/or large amounts of fluid or blood. The catheter can also allow measurement of a "central venous pressure" which helps gauge the filling of the heart.
