What is the minimum blood flow required for a new fistula according to the Rule of 6's?

The minimum blood flow required for a newly created arteriovenous fistula, based on the Rule of 6's, is 600 mL/min. This concept is critical for ensuring that the fistula is mature enough to provide adequate blood flow during dialysis treatments. The Rule of 6's states that for a fistula to be considered suitable for dialysis, it should have a diameter of at least 6 mm, a depth of at least 6 mm, and should achieve a blood flow rate of at least 600 mL/min at the time of evaluation, typically around six weeks after creation.

Having a blood flow of 600 mL/min ensures that the fistula can effectively deliver enough blood for the hemodialysis process, thereby increasing the chances for a successful and efficient treatment. If the blood flow is below this threshold, it may indicate that the fistula is not adequately developed or may require further intervention.
