What is a central line catheter used for?
A central venous catheter is a thin, flexible tube that is inserted into a vein, usually below the right collarbone, and guided (threaded) into a large vein above the right side of the heart called the superior vena cava. It is used to give intravenous fluids, blood transfusions, chemotherapy, and other drugs.
What conditions require a central line?
A central line may be used for a number of reasons:
- Fluid resuscitation : This is when an individual is given large amounts of IV fluids.
- Blood draw: Individuals who need frequent blood draws may have a central line placed.
- Dialysis : In some cases, two lumens on the central line can be used to perform dialysis.
What are the indications for PICC central line?
A PICC line is commonly recommended for:
- Cancer treatments. Medicines that are infused through a vein, such as some chemotherapy and targeted therapy drugs, can be delivered through a PICC line.
- Liquid nutrition (total parenteral nutrition).
- Infection treatments.
- Other medications.
Where are central lines commonly placed and why?
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).
What is the difference between a central line and a peripheral IV line?
A peripheral IV line (PIV, or just “IV”) is a short catheter that’s typically placed in the forearm. It starts and ends in the arm itself. A PICC line is a longer catheter that’s also placed in the upper arm. Its tip ends in the largest vein of the body, which is why it’s considered a central line.
What happens if CVP is low?
A decrease in central venous pressure is noted when there is more than 10% of blood loss or shift of blood volume. A decrease in intrathoracic pressure caused by forced inspiration causes the vena cavae to collapse which decreases the venous return and, in turn, decreases the central venous pressure.
Does a central line go into the heart?
A central line (or central venous catheter) is like an intravenous (IV) line. But it is much longer than a regular IV and goes all the way up to a vein near the heart or just inside the heart. A patient can get medicine, fluids, blood, or nutrition through a central line. It also can be used to draw blood.
How do you calculate CVP pressure?
Find the mean of the A wave.
- read the high point of the A wave.
- read the low point of the A wave.
- add the high point to the low point.
- divide the sum by 2.
- the result is the mean CVP.
What is the normal CVP pressure?
A normal central venous pressure reading is between 8 to 12 mmHg. This value is altered by volume status and/or venous compliance.
What are the indications for central venous line placement?
Some indications for central venous line placement include fluid resuscitation, blood transfusion, drug infusion, central venous pressure monitoring, pulmonary artery catheterization, emergency venous access for patients in which peripheral access cannot be obtained, and transvenous pacing wire placement.

Do all critically ill patients need central venous catheters?
Central venous catheters (CVC) are commonplace in the management of critically ill patients and serve a variety of purposes. Venous access is important for the administration of fluid and medications as well as blood procurement needed for lab analyses. However, not every critically ill patient requires a CVC.
What is an example of a long-term central catheter?
Long-term central catheters. This type of venous catheter persists in situ form for months to several years. Examples include the following, Implantable Venous Access Device (IVADs), Peripherally Inserted Central Catheters (PICCs), Tunneled CVCs. Implantable Venous Access Device: It can also be identified as a port.
