Quickly estimate FiO2 (Fraction of Inspired Oxygen) for patients receiving supplemental oxygen via nasal cannula with this free online calculator. Healthcare professionals and students can easily determine the oxygen percentage delivered and understand its importance in respiratory management. Learn the simple FiO2 formula and interpret results for patient care.
Formula:
FiO2 (%) = 21 + (4 × Oxygen Flow Rate (L/min))
Where:
- FiO2: Fraction of Inspired Oxygen (in percent)
- Oxygen Flow Rate: Oxygen delivery rate via nasal cannula in Liters per minute (L/min)
