What needle gauge is recommended for a blood flow rate (BFR) prescription of 400 ml/min?

For a blood flow rate (BFR) prescription of 400 ml/min, the recommended needle gauge is typically 15 gauge. This is due to the need for a needle size that can accommodate higher flow rates effectively, while also reducing the risk of complications such as hemolysis or clotting.

A 15 gauge needle allows for the necessary flow of blood at the required rate, ensuring efficient dialysis treatment. This gauge strikes a balance between providing a sufficient diameter for the rapid movement of blood and minimizing discomfort for the patient.

While larger gauges, such as 14 gauge, might also be able to handle the flow rate, the use of a 15 gauge needle is preferred in practice for maintaining adequate comfort and reducing the potential for adverse effects during dialysis.
