A central venous access device (CVAD) is primarily a venous catheter specifically designed for the delivery of medication, fluids, blood products, and nutrition directly into major veins, often those leading to the heart. This method is crucial for patients who require long-term intravenous therapy or who may need frequent access to the bloodstream.

The major veins used for CVADs include the internal jugular vein, subclavian vein, or femoral vein. This access enables healthcare providers to administer treatments effectively, manage critical care patients, and conduct blood sampling without the need for repeated needle sticks. The use of a central venous catheter can improve patient comfort and reduce the risk of complications associated with peripheral venous access.

Thus, the description of a CVAD as a venous catheter to deliver medication and fluids into major veins accurately captures its primary function and importance in clinical settings.
