A central venous catheter (CVC) is a thin, flexible tube inserted into a large vein, usually 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 need long-term treatment, such as those undergoing chemotherapy or requiring frequent blood draws. These catheters can also monitor central venous pressure, which helps assess heart function and fluid status. CVCs are essential tools in hospitals, especially in critical care settings, ensuring that patients receive the necessary care efficiently and safely.
