What does the acronym "CVC" refer to in vascular access?

The acronym "CVC" refers to "Central Venous Catheter." A central venous catheter is a long, thin, flexible tube that is inserted into a large vein, commonly in the neck, chest, or groin. It is used for a variety of purposes including administering medications, fluids, blood products, or nutrients, as well as for measuring central venous pressure. The key features of a central venous catheter include its ability to provide access to the central circulation, facilitating therapies that require large volumes or irritant medications that would cause damage if administered through peripheral veins.

Understanding the proper terminology is crucial in vascular access, especially when discussing various types of catheters and their applications in clinical practice. The other options present variations of the term but do not accurately reflect the definition or function of "CVC" in a clinical context.
