Which type of vascular access device is typically used for short-term use?

Peripheral intravenous (IV) catheters are typically used for short-term access to a patient's venous system. These catheters are designed for quick insertion and are ideal for administering medications, fluids, and collecting blood samples over a limited duration, usually up to several days. Their ease of placement allows for rapid initiation of therapy, making them suitable for situations where immediate access is needed or where the duration of treatment is not expected to be prolonged.

In contrast, central venous catheters are intended for longer-term use, generally inserted when extended infusion therapy or frequent blood sampling is required. Peripherally inserted central catheters, while also designed for longer duration therapies, serve similar purposes but can accommodate therapies that may require central access over weeks or months. Implantable ports are implanted under the skin and used for long-term venous access, typically in patients needing ongoing treatment or repeated access for an extended period.

The focus on the short-term application of peripheral IV catheters makes them the appropriate choice for this question, as they are the go-to device for immediate and temporary vascular access needs.
