SAVE Score Calculator (Schmidt 2015)
x402
SAVE Score Calculator (Schmidt 2015) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Survival After Veno-Arterial ECMO (SAVE) integer score from Table 4 of Schmidt 2015, returning a risk class (I–V) and associated hospital survival probability.

How this service works
Schmidt 2015 SAVE-score from Table 4 integer cells plus constant −6. Age, weight, additive diagnoses, chronic renal failure, acute liver/CNS/renal failure, intubation hours, PIP ≤20, cardiac arrest, diastolic BP ≥40, pulse pressure ≤20, bicarbonate ≤15. Class I–V hospital survival 75/58/42/30/18%. Range −35 to 17. Not a VA-ECMO assignment. Not modified SAVE.
Output
Returns the integer SAVE score (range −35 to 17), the corresponding risk class (I through V), and the associated predicted hospital survival percentage (75%, 58%, 42%, 30%, or 18%) based on Schmidt 2015 Table 4.
Example use cases
Pre-ECMO mortality stratification in ICU
“I have a 63-year-old, 72 kg patient in cardiogenic shock — no myocarditis, no transplant history, no congenital heart disease, no refractory VT/VF, acute renal failure present, chronic renal failure absent, no liver failure, no CNS dysfunction, no pre-ECMO cardiac arrest, been intubated 12 hours, peak inspiratory pressure 25 cmH2O, diastolic BP 35 mmHg, pulse pressure 22 mmHg, bicarbonate 14 mmol/L. Run the SAVE score and tell me which class she falls into and what the survival odds are.”
Myocarditis patient ECMO candidacy scoring
“Score a 32-year-old, 60 kg patient with confirmed acute myocarditis for VA-ECMO using the SAVE score — no cardiac arrest, no organ failures, intubated 3 hours, PIP 17 cmH2O, diastolic BP 55 mmHg, pulse pressure 28 mmHg, bicarb 20 mmol/L. What SAVE class and predicted survival percentage does he get?”
Post-cardiac arrest VA-ECMO risk assessment
“A 58-year-old weighing 95 kg had a cardiac arrest before ECMO cannulation, has acute liver failure and CNS dysfunction, chronic renal failure, no myocarditis, no transplant, no congenital disease, no refractory VT/VF, intubated 48 hours, PIP 30 cmH2O, diastolic BP 30 mmHg, pulse pressure 18 mmHg, bicarbonate 12 mmol/L — calculate his SAVE score and tell me which risk class and survival probability that corresponds to.”

Endpoint
GEThttps://api.magentlab.com/api/calc/saveWhen to prefer
Use this endpoint when you need the original Schmidt 2015 integer-cell SAVE score (with the −6 constant) for adult VA-ECMO candidacy or outcome prediction. Choose this over generic mortality calculators when the clinical context is specifically veno-arterial ECMO for cardiogenic shock. Do not use if you need the modified SAVE score, VV-ECMO risk, pediatric scoring, or VA-ECMO assignment logic — this endpoint only computes the arithmetic score and returns the class.
Side effects
- Missing required query parameters (age, weight_kg, any boolean flag, or continuous variables) returns a 400 error
- Out-of-range numeric inputs (e.g. age <18, weight outside 20–400 kg) may return a validation error
- Non-integer age value may be rejected
- Payment failure or missing x402 header returns a 402 Payment Required response
- Score reflects only adult VA-ECMO patients; pediatric or VV-ECMO use is not supported by this calculator
