SIRS Criteria Calculator

SIRS Criteria CalculatorCanineFeline

Evaluate systemic inflammatory response syndrome (SIRS) criteria in dogs and cats using species-specific thresholds. Checks temperature, heart rate, respiratory rate, and white blood cell count against established SIRS parameters. Canine SIRS: temp >39.2°C/102.5°F or <38.1°C/100.5°F, HR >120 bpm, RR >20 breaths/min, WBC >16×10³/µL or <6×10³/µL. Feline SIRS: temp >39.7°C/103.5°F or <37.8°C/100°F, HR >225 or <140 bpm, RR >40 breaths/min, WBC >19×10³/µL or <5×10³/µL. SIRS positive in dogs when ≥2 criteria met, in cats when ≥3 criteria met. Used for sepsis screening, systemic inflammation assessment, critical care triage, post-surgical monitoring, and infection workup.
