🫀 SAVE Score (VA-ECMO Survival)
UseWhen to use: refractory cardiogenic shock before VA cannulation.
StrataClasses 0–IV approximate survival ~18%→75%.
LimitsWhen not to use: VV ECMO respiratory failure alone. · Pitfall: missing chronic kidney (−6). · Not a sole futility label.

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.

|---|---|
| Weight | 65–89 kg (+2) |
| Acute myocarditis | No (0) |
| Refractory VT/VF | No (0) |

| Congenital heart disease | No (0) |
| Acute renal failure | No (0) |
| Chronic renal failure | No (0) |
| HCO₃ ≤15 mmol/L pre-ECMO | No (0) |
| Intubation duration pre-ECMO | 11–29 h (−2) |
| PIP ≤20 cmH₂O | No (0) |

FAQ
Frequently asked questions
- Does SAVE Score (VA-ECMO Survival) 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 SAVE Score (VA-ECMO Survival) calculated in practice? Can you show a worked example?
- Inputs: Age 39–52 (+4), Weight 65–89 kg (+2), Acute myocarditis No (0), Refractory VT/VF No (0), Post heart/lung transplant No (0), Congenital heart disease No (0), Acute renal failure No (0), Chronic renal failure No (0)… → Result: SAVE 4 pts（Risk class: Class III (1–5) — ~58%） Inputs: Age 18–38 (+7), Weight <65 kg (+1), Acute myocarditis No (0), Refractory VT/VF No (0), Post heart/lung transplant No (0), Congenital heart disease No (0), Acute renal failure No (0), Chronic renal failure No (0)… → Result: SAVE 8 pts（Risk class: Class IV (≥6) — ~75%）
