These catheters are commonly placed in veins in the neck ( internal jugular vein), chest ( subclavian vein or axillary vein), groin ( femoral vein), or through veins in the arms (also known as a PICC line, or peripherally inserted central catheters).Ĭentral lines are used to administer medication or fluids that are unable to be taken by mouth or would harm a smaller peripheral vein, obtain blood tests (specifically the "central venous oxygen saturation"), administer fluid or blood products for large volume resuscitation, and measure central venous pressure. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged intravenous therapies, for more reliable vascular access. A central venous catheter ( CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. ![]()
