More about: SOFA (ext.)

What it calculates

The “SOFA (ext.)” calculator computes SOFA score from 13 parameters: pao₂ (mmHg), fio₂ (%), mechanical ventilation / respiratory support (1 = yes), platelets (×10⁹/L), bilirubin (µmol/L), mean arterial pressure (mmHg), dopamine (µg/kg/min), dobutamine at any dose (1 = yes), norepinephrine (µg/kg/min), epinephrine (µg/kg/min), glasgow coma scale (points), creatinine (µmol/L), urine output (mL/day).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters PaO₂ = 90 mmHg, FiO₂ = 21 %, Mechanical ventilation / respiratory support (1 = yes) = 0, Platelets = 200 ×10⁹/L, Bilirubin = 15 µmol/L, Mean arterial pressure = 80 mmHg, Dopamine = 0 µg/kg/min, Dobutamine at any dose (1 = yes) = 0, Norepinephrine = 0 µg/kg/min, Epinephrine = 0 µg/kg/min, Glasgow Coma Scale = 15 points, Creatinine = 90 µmol/L, Urine output = 1,500 mL/day the result is 0 (A SOFA increase of ≥2 points with infection defines sepsis (Sepsis-3)).

How to use

  1. Enter pao₂, fio₂, mechanical ventilation / respiratory support (1 = yes), platelets, bilirubin, mean arterial pressure, dopamine, dobutamine at any dose (1 = yes), norepinephrine, epinephrine, glasgow coma scale, creatinine and urine output — each field above is adjustable with a slider.
  2. SOFA score is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.
  4. Copy the result or bookmark this calculator.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
