Venous catheter, central

Venous catheter, central
A catheter (a tube) that is passed through a vein to end up in the thoracic (chest) portion of the vena cava (the large vein returning blood to the heart) or in the right atrium of the heart. Central venous catheters have a diversity of uses. They allow concentrated solutions to be infused with less risk of complications. They permit monitoring of the central venous pressure, the pulmonary artery pressure, and the pulmonary capillary wedge pressures. They can be used for the estimation of cardiac output and vascular resistance. The near end of the catheter may also be connected to a chamber for injections given over periods of months. A central venous catheter is also called a central venous line. Sometimes, the "venous" is omitted and it is called a central catheter or central line.
