Which of the following is a type of Central Venous Access Device (CVAD)?

Implanted subcutaneous ports are indeed a type of Central Venous Access Device (CVAD). These devices are designed for long-term venous access and can be used to administer medications, fluids, blood products, and for blood sampling. The port is surgically placed under the skin, typically on the chest, with a catheter that runs into a major vein, allowing for easy access with a special needle.

Central Venous Access Devices, such as implanted ports, are primarily used for patients who require frequent or continuous venous access, such as those undergoing chemotherapy or long-term antibiotic therapy. The subcutaneous ports minimize the risk of infection compared to external devices, making them suitable for extended periods of use.

In contrast, the other options listed—peripheral intravenous catheters, intraosseous access devices, and standard IV cannulas—are not classified as central venous access devices. Peripheral catheters and standard IV cannulas are specifically used for short-term access through the veins in the arms or hands and do not reach the central venous circulation. Intraosseous devices are utilized for emergency situations to provide access through the bone marrow when intravenous access is challenging but are not considered central vascular access either.
