Sandbox tachy2

Sepsis = infection (documented or suspected) and some of the following:

General variables Fever (>38.3°C) Hypothermia (core temperature <36°C) Heart rate >90/min–1 or more than two SD above the normal value for age Tachypnea Altered mental status Significant edema or positive fluid balance (>20 mL/kg over 24 hr) Hyperglycemia (plasma glucose >140mg/dL or 7.7 mmol/L) in the absence of diabetes

Inflammatory variables Leukocytosis (WBC count >12,000 μL–1) Leukopenia (WBC count <4000 μL–1) Normal WBC count with greater than 10% immature forms Plasma C-reactive protein more than two SD above the normal value Plasma procalcitonin more than two SD above the normal value

Hemodynamic variables Arterial hypotension (SBP <90mm Hg, MAP <70mm Hg, or an SBP decrease >40mm Hg in adults or less than two SD below normal for age)

Organ dysfunction variables Arterial hypoxemia (Pao2/Fio2 <300) Acute oliguria (urine output <0.5 mL/kg/hr for at least 2 hrs despite adequate fluid resuscitation) Creatinine increase >0.5mg/dL or 44.2 μmol/L Coagulation abnormalities (INR >1.5 or aPTT >60 s) Ileus (absent bowel sounds) Thrombocytopenia (platelet count <100,000 μL–1) Hyperbilirubinemia (plasma total bilirubin >4mg/dL or 70 μmol/L)

Tissue perfusion variables Hyperlactatemia (>1 mmol/L) Decreased capillary refill or mottling
