A central venous catheter (CVC) is a thin, flexible tube inserted into a large vein, typically in the neck, chest, or groin. It allows healthcare providers to deliver medications, fluids, and nutrients directly into the bloodstream. CVCs are often used for patients who require long-term intravenous therapy or have difficult venous access. The procedure to place a CVC is usually performed by a trained medical professional, such as a doctor or nurse. The catheter can also be used to monitor central venous pressure, which helps assess a patient's heart function and fluid status. Proper care and maintenance of the CVC are essential to prevent infections and complications.
