Which type of vein is commonly used for peripheral IV access?

The cephalic vein is commonly used for peripheral IV access because it is located on the lateral aspect of the forearm and upper arm, making it easily accessible for catheter insertion. This vein is relatively large, has good blood flow, and is often visible or palpable, which facilitates the insertion process.

Additionally, using the cephalic vein minimizes the risk of complications associated with deeper veins, such as the femoral or jugular veins, which are typically used for central venous access. Peripheral IV access aims to provide a safe, effective way to administer fluids, medications, and obtain blood samples without the complexities associated with central lines. Thus, the characteristics of the cephalic vein, including its accessibility and size, make it a favorable choice for peripheral intravenous access.
