Using a slower blood flow rate initially is a well-recognized technique to minimize hypotension during hemodialysis treatment. When a patient’s blood flow rate is decreased at the start of dialysis, it allows their body to acclimatize more gradually to the changes in fluid volume and pressure. This gradual approach can help maintain hemodynamic stability, especially in patients who are prone to hypotension or who may have an unstable cardiovascular status.

Starting with a slower blood flow rate reduces the risk of rapid shifts in blood volume and pressure, making it easier for the body to adapt to the dialysis process. Once the patient is stable, the blood flow rate can typically be increased to the prescribed level. This technique is especially important for patients who experience symptomatic hypotension or other complications during their dialysis sessions.

In contrast, using a higher blood flow rate immediately would increase the risk of hemodynamic instability and hypotension. Increasing the volume of dialysate could also contribute to fluid shifts that might lead to hypotension. Advancing treatment to shorter durations does not address the underlying issues related to blood flow and hemodynamic stability during the session. Thus, starting with a slower blood flow rate is a more effective strategy to maintain stability throughout the treatment.
