PRESET-Score Calculator (Hilder 2017) – ECMO Mortality Risk
x402
PRESET-Score Calculator (Hilder 2017) – ECMO Mortality Risk 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 Hilder 2017 PRESET score from five clinical parameters and returns the ICU mortality risk class (I, II, or III) for patients being considered for ECMO.

How this service works
Hilder 2017 PRESET-Score: five Table 4 items (MAP mm Hg, lactate mmol/L, arterial pH, platelets k/uL, hospital days pre-ECMO) summed 0-15. Returns class I (0-5, 26% ICU mortality), II (6-9, 68%), or III (10-15, 93%) from the derivation cohort. Deterministic published arithmetic with citation; not a cannulation order; magent does not assay labs. Not RESP or SAVE.
Output
Returns the total PRESET integer score (0–15) and the corresponding risk class: Class I (score 0–5, ~26% ICU mortality), Class II (score 6–9, ~68% ICU mortality), or Class III (score 10–15, ~93% ICU mortality), based on the Hilder 2017 derivation cohort arithmetic.
Example use cases
Pre-ECMO ICU Mortality Stratification
“I need the PRESET score for an ICU patient about to go on ECMO: MAP is 68 mm Hg, lactate 3.8 mmol/L, arterial pH 7.18, platelets 110 k/µL, and they've been in hospital for 5 days. What's their risk class?”
Comparing Two ECMO Candidates
“Run the Hilder PRESET calculation for two patients — first: MAP 95, lactate 1.2, pH 7.35, platelets 220, 1 day pre-ECMO; second: MAP 58, lactate 9.0, pH 7.05, platelets 80, 10 days pre-ECMO — and tell me what mortality class each falls into.”
Clinical Documentation of ECMO Risk Score
“What's the PRESET score and ICU mortality risk class for a patient with MAP 82 mm Hg, lactate 2.1 mmol/L, arterial pH 7.28, platelets 160 k/µL, and 2 hospital days before ECMO? I need the class and derivation-cohort mortality estimate for the chart.”

Endpoint
GEThttps://api.magentlab.com/api/calc/presetWhen to prefer
Use this endpoint when you need fast, deterministic Hilder 2017 PRESET score arithmetic for ECMO mortality risk classification and have all five required clinical values (MAP, lactate, arterial pH, platelets, hospital days pre-ECMO). Prefer this over RESP or SAVE scores when specifically implementing the PRESET tool. It is not a substitute for clinical judgment or a cannulation order.
Side effects
- Missing required parameters (MAP, lactate, pH, platelets, or hospital days) returns a 400 validation error
- Out-of-range values (e.g. pH outside 6.5–8.0, platelets >2000) may be rejected or produce unexpected scoring
- Endpoint does not assay labs — input must come from verified clinical measurements
- Non-numeric values for numeric fields will cause request failure
- Payment failure (x402) if USDC balance is insufficient
