Sequential Organ Failure Assessment (SOFA) Score

Partial pressure of oxygen, PaO₂

Fraction of inhaled oxygen, FiO₂

Platelet count

Bilirubin

Blood pressure (catecholamines administered for at least 1 hour)

SBP (mmHg) (optional, for MAP calculation)

mmHg

DBP (mmHg) (optional, for MAP calculation)

mmHg

Calculate MAP

mmHg

A. Mean arterial pressure ≥70 mmHg
B. Mean arterial pressure <70 mmHg
C. On dopamine <5 µg/kg/minute, or dobutamine (any dose)
D. On dopamine >5.1-15 µg/kg/minute, or epinephrine/norepinephrine ≤0.1 µg/kg/minute
E. On dopamine >15 µg/kg/minute, or epinephrine/norepinephrine >0.1 µg/kg/minute

Glasgow coma scale score

Creatinine

Urine output

Formula

Sequential [Sepsis-Related] Organ Failure Assessment Score Table

¹Use of mechanical ventilation is assumed for the categories “PaO₂/FiO₂ <200” and “PaO₂/FiO₂ <100”
²MAP: Mean arterial pressure
³Catecholamine doses are given as μg/kg/minute for at least 1 hour.

Mortality during intensive care unit stay for maximum SOFA score

Maximum SOFA score	Mortality during ICU stay
0-9	<25%
10-14	40-60%
15	>80%
>15	>90%
