High-Volume Hemodiafiltration: Understanding a Dialysis Treatment Approach
Dr. Stefano Stuard, MD, PhD, Nephrologist Dr. Michael Anger, MD, Nephrologist Overview: Hemodiafiltration (HDF) is a type of dialysis that cleans the blood using two cleaning processes: diffusion and convection. Standard hemodialysis mainly relies on diffusion alone. Diffusion and convection remove waste in different ways. Diffusion helps remove smaller waste products, while convection helps move larger waste substances out of the blood. Using both processes allows for a broader range of waste removal during treatment. High-volume hemodiafiltration refers to HDF treatments that use a larger amount of clean, sterile replacement fluid during the dialysis session, [...]
