HDF Planner

Online haemodiafiltration. Enter the session settings; the tool checks the effective convection volume against the ≥23 L/session target and gives the sequential way to reach it. Postdilution is the preferred mode.

⚠️ Decision aid, not a directive. Based on UpToDate prescribing guidance for chronic intermittent high-volume HDF. Suggestions are starting points to individualise and verify against the patient, machine, and local protocol. Postdilution targets effective convection volume ≥23 L/session (BSA-adjusted where appropriate) plus Kt/V 1.2–1.4. Developed by Dr. Abbas Deeb · not affiliated with UpToDate.
