What is a Central Venous Access Device (CVAD)?

• A. A catheter placed in a large vein for blood pressure monitoring
• B. A catheter placed in a large vein to administer medication, fluids, or draw blood
• C. A device used to monitor cardiac functions
• D. A temporary device used to access peripheral veins

Answer: (B)

A Central Venous Access Device (CVAD) is specifically designed to be placed in a large vein, typically the superior vena cava or one of its large branches, for the purpose of administering medications, fluids, or nutrients, and also for drawing blood samples. The central placement of the CVAD allows for the delivery of therapies that may be irritating to peripheral veins, such as certain chemotherapeutic agents, and enables rapid access to the central circulation for urgent medical needs. Additionally, CVADs facilitate long-term treatment regimens and can remain in place for extended periods, which is beneficial for patients requiring repeated access for infusions or blood draws. This functionality distinguishes it from devices like those used solely for monitoring blood pressures or cardiac functions, as these do not serve the primary purpose of providing medication delivery or fluid therapy.
