SOFA Score: SOFA-2 & SOFA

SOFA score calculator for organ dysfunction in ICU patients. Both versions of the score: the updated SOFA-2 (2025) and the original SOFA (1996). Made for intensivists, anesthesiologists and residents. SOFA-2 (2025) • Points for six systems: respiratory, cardiovascular, liver, kidney, hemostasis and brain • PaO₂/FiO₂, or SpO₂/FiO₂ when no blood gas is available • HFNC, CPAP and NIV, invasive ventilation and ECMO • Combined norepinephrine and epinephrine dose, dopamine, dobutamine, other vasopressors and inotropes, mechanical circulatory support • Creatinine, oliguria and renal replacement therapy • Glasgow Coma Scale (GCS) and drugs to treat delirium Original SOFA (1996) Use it on its own or see it next to SOFA-2, from the same data. Calculators • qSOFA • Glasgow Coma Scale by its three components, with brain points for SOFA • Vasopressors: syringe pump rate to µg/kg/min and back, norepinephrine salt converted to base • Respiration: PaO₂/FiO₂, SpO₂/FiO₂, ideal body weight by the Devine formula and volumes for 4, 6 and 8 mL/kg Made for daily work • Results update as you type • The current score stays under the title, with a button to jump to the result • Mean arterial pressure from systolic and diastolic, and GCS, calculated right from the form • Bilirubin and creatinine in µmol/L or mg/dL • Input checks: implausible values are not accepted, and unusually high doses are flagged • Ready-made summary: copy with one tap or send to a messenger • Reference tab: all cut-offs of both versions, formulas and links to sources • Light and dark theme Sources • Ranzani OT et al.

Check drug doses and infusion rates against the drug label and the physician's order. This app is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, diagnosis, or treatment.
