SOFA Score Calculator

Calculate the Sequential Organ Failure Assessment (SOFA) score to evaluate organ dysfunction in ICU patients.

Respiration (PaO₂/FiO₂, mmHg)

Coagulation (Platelets ×10³/μL)

Liver (Bilirubin mg/dL)

Cardiovascular

CNS (Glasgow Coma Scale)

Renal (Creatinine mg/dL or urine output)

How to Use the SOFA Score Calculator

Select the score (0–4) for each of the 6 organ systems.
Base scores on the current or worst values during the assessment period.
Click 'Calculate' to see the total SOFA score and mortality estimate.

使用例

•Tracking organ dysfunction in ICU patients.
•Diagnosing sepsis (increase ≥2 from baseline).
•Predicting ICU mortality.

計算式

SOFA = sum of 6 organ system scores (Respiration, Coagulation, Liver, Cardiovascular, CNS, Renal). Each scored 0–4. Max = 24.

よくある質問

What is the SOFA score?

The Sequential Organ Failure Assessment (SOFA) score is used to track a patient's status during their ICU stay. It evaluates dysfunction in 6 organ systems: respiratory, coagulatory, hepatic, cardiovascular, neurological, and renal.

How is SOFA interpreted?

SOFA 0–6: <10% mortality. SOFA 7–9: 15–20%. SOFA 10–12: 40–50%. SOFA ≥13: >50% mortality. An increase ≥2 points indicates sepsis.
