How to Use SOFA Score Calculator
The SOFA Score Calculator focuses on how to score six organ systems: respiration, coagulation, liver, cardiovascular function, central nervous system, and kidney function. Follow these steps:
- Enter PaO2/FiO2 and whether respiratory support is being used
- Enter platelets, bilirubin, cardiovascular support category, GCS, creatinine, and urine output
- Read each organ-system subscore before interpreting the total
- When used clinically, compare repeat SOFA scores over time rather than relying on a single value
Formula & Theory — SOFA Score Calculator
The SOFA Score Calculator uses the following calculation logic:
SOFA total = respiratory score + coagulation score + liver score + cardiovascular score + CNS score + renal score
Each organ system contributes 0 to 4 points.
Renal score uses the worse value from creatinine and urine output when both are available.SOFA measures organ dysfunction rather than a single diagnosis. A patient can reach the same total through different combinations of organ-system failure, so the subscore pattern is as important as the final number.
Use Cases for SOFA Score Calculator
The SOFA Score Calculator is most useful in these situations:
- Sepsis and organ dysfunction education.
- Tracking deterioration or recovery in ICU case discussions.
- Showing which organ system is driving a high total score.
