Clinical use
Use this calculator for systemic inflammatory response syndrome in theemergency medicine workflow. It is decision support and should be interpreted with the patient context, local protocols, and clinician judgment.
Calculate SIRS
Interpretation
≥2 criteria = SIRS. SIRS + suspected infection = sepsis (legacy definition). Sepsis-3 (2016) now uses SOFA/qSOFA. SIRS remains useful for early inflammatory response detection.
Required inputs
- Temperature
- Heart Rate
- Respiratory Rate
- Wbc
Optional: Paco 2, Band Forms, Suspected Infection
