🩺 Ultrafiltration Rate (UFR)
UseWhen to use: intradialytic risk review when UF volume, post weight, and session length are known.
StrataHigher UFR bands cue consideration of longer dialysis or lower interdialytic gains.
LimitsWhen not to use: wrong weight basis. · Pitfall: chasing UFR without symptoms context. · Thresholds are teaching cues.

When to use
When to use: intradialytic risk review when UF volume, post weight, and session length are known.
How it works
UFR = (UF L × 1000) / (post-weight kg × hours).
Key points
- mL/kg/h.
- Intradialytic risk adjunct.
- Next: dry weight / time.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| UF volume | 2.5 L |
|---|---|
| Post-dialysis weight | 70 kg |
| Session length | 4 hours |
→UFR8.9mL/kg/h
- UF：2.50 L
- Cue：≤10 mL/kg/h — lower UFR teaching band

FAQ
Frequently asked questions
- Does Ultrafiltration Rate (UFR) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Ultrafiltration Rate (UFR) calculated in practice? Can you show a worked example?
- Inputs: UF volume 2.5 L, Post-dialysis weight 70 kg, Session length 4 hours → Result: UFR 8.9 mL/kg/h（UF: 2.50 L, Cue: ≤10 mL/kg/h — lower UFR teaching band）
