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 ug/kg/minute, or dobutamine (any dose)
D. On dopamine > 5 ug/kg/minute, or Epi/Norepi < 0.1 ug/kg/minute
E. On dopamine > 15 ug/kg/minute, or Epi/Norpei > 0.1/kg/minute

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%
