Final answer:
A port is considered a permanent type of Vascular Access Device (VAD), useful for patients who require long-term intravenous therapy. They are implanted under the skin, connected to a vein near the heart, and designed to stay in place for years. Other VADs like fistulas, PICCs, and IV lines are not considered permanent.
Step-by-step explanation:
The type of Vascular Access Device (VAD) that is considered a permanent device is c. Port. Fistulas are created for long-term dialysis in patients with renal failure and can be considered semi-permanent but may not be used for the lifetime of the patient. A Peripherally Inserted Central Catheter (PICC) is not designed to be permanent and is typically used for weeks to months. An Intravenous (IV) line is for short-term use, often changed every few days, to reduce the risk of infection and maintain access functionality.
Ports are implanted under the skin and consist of a reservoir attached to a tube that goes directly into a large vein near the heart. They can remain in place for extended periods, often years, and are designed for patients who require long-term intravenous therapy, such as those receiving chemotherapy, long-term antibiotics, or other medications. Their design allows for repeated access with special needles, reducing the discomfort and infection risk associated with other types of VADs.
