SIRS Criteria Calculator (Bone 1992 ACCP/SCCM)
x402
SIRS Criteria Calculator (Bone 1992 ACCP/SCCM) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).
Calculates Systemic Inflammatory Response Syndrome (SIRS) score using the classic Bone 1992 ACCP/SCCM four-criterion definition, returning whether SIRS is present (≥2 of 4 criteria met).

How this service works
Deterministic published-formula arithmetic plus ICD-10-CM, RxNorm, and LOINC. Pay in USDC on Base via x402.
Output
Returns a structured object indicating whether SIRS is present (true/false), the total number of SIRS criteria met (0–4), and the individual pass/fail result for each of the four criteria: temperature, heart rate, respiratory/PaCO2, and WBC/bands.
Example use cases
ICU sepsis screening from chart values
“I'm reviewing an ICU patient: temp 35.8 °C, heart rate 95 bpm, respiratory rate 18, and WBC 3,200 per µL. How many SIRS criteria are met and is SIRS present?”
ED triage SIRS check with PaCO2
“Patient in the ED has temperature 39.1 °C, heart rate 110 bpm, respiratory rate 24 breaths/min, and arterial PaCO2 of 29 mm Hg — do they meet Bone 1992 SIRS criteria?”
Automated chart review with band count
“Run SIRS scoring on this CBC and vitals: temperature 37.2 °C, heart rate 88 bpm, respiratory rate 19, WBC 11,000 per µL, and bands at 13%. Is SIRS positive?”

Endpoint
GEThttps://api.magentlab.com/api/calc/sirs?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, citation-backed SIRS calculation per the original Bone 1992 ACCP/SCCM definition. Prefer it over manual rule-coding when building clinical decision support, sepsis screening pipelines, or automated chart review tools. Note this is NOT Sepsis-3, qSOFA, or SOFA — choose it explicitly when the older SIRS framework is required (e.g., for legacy protocols, research replication, or insurance/billing workflows referencing Bone 1992).
Side effects
- Missing required parameters (temperature_c, heart_rate_bpm, respiratory_rate) returns a 400 error
- Temperature out of range 30.0–45.0 °C rejected
- Heart rate outside 30–220 bpm rejected
- Respiratory rate outside 4–80 rejected
- WBC value out of accepted range rejected
- Payment not included or invalid returns 402 Payment Required
- Providing both wbc_ul and wbc_k_ul may cause ambiguity — prefer one unit
