central venous catheter

Description

A catheter (flexible tube) that is passed through a vein in the neck, groin or chest into the vena cava (the large vein leading into the heart).

A central venous catheter may be used to give continuous infusion of fluids, deliver drugs or collect blood samples. It may also be used to measure the pressure of the blood returning to the heart (central venous pressure or CVP) and how much blood the heart is pumping.

Also called central line, central venous line or central venous access catheter.
