UseWhen to use: shock phenotyping and indexed hemodynamic reporting.

StrataLow SVI cues limited forward stroke volume — interpret with SVR and filling pressures.

LimitsWhen not to use: wrong BSA. · Pitfall: mixing CO with CI formulas. · Size-dependent bands.

Clinical takeaway

SV/BSA or CI×1000/HR.

When to use

When to use: shock phenotyping and indexed hemodynamic reporting.

How it works

SVI = SV/BSA = CI×1000/HR.

Key points

  • SV/BSA or CI×1000/HR.
  • Indexed SV.
  • Next: LVSWI / SVR.

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 Index (SVI) 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 Index (SVI) calculated in practice? Can you show a worked example?
Inputs: Input mode SV + BSA, Stroke volume 70 mL, BSA 1.8 m², Cardiac index 2.8 L/min/m², Heart rate 80 /min → Result: SVI 38.9 mL/beat/m²（From: SV/BSA, Cue: ≈30–65 — common adult indexed band (source-dependent)） Inputs: Input mode CI + HR, Stroke volume 70 mL, BSA 1.8 m², Cardiac index 2.8 L/min/m², Heart rate 80 /min → Result: SVI 35.0 mL/beat/m²（From: CI×1000/HR, Cue: ≈30–65 — common adult indexed band (source-dependent)）
