When to use

When to use: controlled ventilation patients being assessed for fluid responsiveness.

How it works

SVV = (SVmax − SVmin) / SVmean × 100%.

Key points

  • (SVmax−SVmin)/SVmean×100%.
  • Dynamic ICU adjunct.
  • Next: PPV / PLR.

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.

FAQ

Frequently asked questions

Does Stroke Volume Variation (SVV) 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 Stroke Volume Variation (SVV) calculated in practice? Can you show a worked example?
Inputs: SVmax 80 mL, SVmin 60 mL → Result: SVV 28.6 %（SVmean: 70.0 mL, ΔSV: 20.0 mL, Cue: >≈13% — higher SVV band (fluid-responsiveness cue if applicability met)）
