Clinical takeaway

SpO₂/FiO₂ substitute.

When to use

When to use: bedside / resource-limited settings when ABG or bilirubin is unavailable.

How it works

Sum of 5 systems (0–4 each): SpO₂/FiO₂ lung, CV, GCS, platelets, creatinine (max 20).

Key points

  • SpO₂/FiO₂ substitute.
  • No hepatic component.
  • Next: full SOFA if labs allow.

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.

SpO₂/FiO₂ respiratory points2 — ≤315
Cardiovascular points2 — dopamine ≤5 or any dobutamine
CNS (GCS) points2 — 10–12
Coagulation (platelets) points2 — <100
Renal (creatinine) points2 — 2.0–3.4

FAQ

Frequently asked questions

Does Modified SOFA (mSOFA) 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 Modified SOFA (mSOFA) calculated in practice? Can you show a worked example?
Inputs: SpO₂/FiO₂ respiratory points 2 — ≤315, Cardiovascular points 2 — dopamine ≤5 or any dobutamine, CNS (GCS) points 2 — 10–12, Coagulation (platelets) points 2 — <100, Renal (creatinine) points 2 — 2.0–3.4 → Result: mSOFA 10 /20（Systems: Lung + CV + CNS + Coag + Renal (no bilirubin), Cue: Higher mSOFA — greater organ dysfunction burden） Inputs: SpO₂/FiO₂ respiratory points 0 — SpO₂/FiO₂ >400, Cardiovascular points 0 — MAP ≥70, no pressors, CNS (GCS) points 0 — GCS 15, Coagulation (platelets) points 0 — ≥150, Renal (creatinine) points 0 — Cr <1.2 mg/dL → Result: mSOFA 0 /20（Systems: Lung + CV + CNS + Coag + Renal (no bilirubin), Cue: Lower mSOFA burden）
