FiO2 Titration Calculator

Calculate and titrate the fraction of inspired oxygen (FiO2) to achieve target SpO2 or PaO2 in ICU patients, using ARDSnet tables or oxygen toxicity risk-based guidelines.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate and titrate the fraction of inspired oxygen (FiO2) to achieve target SpO2 or PaO2 in ICU patients, using ARDSnet tables or oxygen toxicity risk-based guidelines

Each component has a specific meaning:

  • ARDSnet tables or oxygen toxicity risk-based guidelines — The ardsnet tables or oxygen toxicity risk-based guidelines recorded for the scenario being assessed.

Note: Interpret the fio2 titration result against the thresholds and context described above.

How to Use

Enter the ARDSnet tables or oxygen toxicity risk-based guidelines for the scenario you are assessing. Calculate and titrate the fraction of inspired oxygen (FiO2) to achieve target SpO2 or PaO2 in ICU patients, using ARDSnet tables or oxygen toxicity risk-based guidelines. Use the fio2 titration result to inform your calculation.
