Important: Inputs must be complete to perform calculation.

 
Total criteria point count:
 
Notes
  • Vasoactive drug dose criteria based on administration for at least 1 hour.
  • The SOFA score helps predict morbidity rather than mortality, though individuals with a score of 15 or more had a mortality rate of 90%.1
  • Refer to the UpToDate topic review on predictive scoring systems in the intensive care unit for information on interpreting the SOFA score.
  • PaO2: arterial partial pressure of oxygen; FiO2: fractional inspired percentage of oxygen.

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
