SIRS/SEPSIS CRITERIA
SIRS = two of the following:
1. Temperature >38 or <36C
2. Heart rate >90 bpm
3. Respiratory rate >20 bpm or PaCO2<32 mmHg
4. WBC >12,000 cells/mm3, <4,000, or >10% bands
Sepsis = SIRS + infection
Severe sepsis = Sepsis + associated organ dysfunction or hypoperfusion (e.g. lactic acidosis, oliguria, altered MS)
Septic shock = Sepsis + hypotension despite adequate fluid resuscitation
