SIRS
Inflammatory Response
For education. Check every result.
Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.
How it is calculated
SIRS: temperature >38 or <36 degrees C, heart rate >90, respiratory rate >20 (or PaCO2 <32 mmHg), white cells >12 or <4 x10^9/L (or >10% bands). Superseded by Sepsis-3 in 2016 for defining sepsis, because it is neither sensitive nor specific for that. It remains a recommended screening tool: Surviving Sepsis 2026 prefers SIRS, NEWS2 or MEWS to qSOFA alone for flagging possible sepsis.
