Catheter, central venous

   A catheter (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.

RELATED TERMS

Catheter
A thin, flexible tube that carries fluids into or out of the body.

Vein
A blood vessel that carries blood from the body back into the heart.

Thoracic
Pertaining to or affecting the chest.

Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.

Atrium

Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.

Catheter, hemodialysis
A venous catheter used for hemodialysis (dialysis of the blood). A hemodialysis catheter is a type of central venous catheter. It may be inserted into the subclavian, internal jugular, or femoral veins. Subclavian catheters generally may be used for 2 to 6 weeks. Hemodialysis catheters are often for relatively short-term use because of an acute need for dialysis or because chronic dialysis is just starting.

Catheter, pulmonary artery

Catheter, Swan-Ganz
A thin, flexible tube that is inserted through one of the large veins (the inferior or superior vena cava) that return blood to the heart. The catheter is flow-directed. It uses a balloon to carry it through the vena cava to the heart, through the right side of the heart (the right atrium and right ventricle) to the pulmonary artery. Once there, the catheter is purposely positioned in a small branch of the pulmonary artery. Then a pressure called the pulmonary wedge pressure is measured in front of the temporarily inflated and wedged balloon.

Catheterization, venous
The insertion of a tiny tube (a catheter) into a peripheral or central vein to deliver fluids or medication. This is the most frequently used method for the administration of intravenous (IV) fluids and IV meds (medications).
