WebApr 24, 2024 · P a O 2 divided by FiO 2 or100 divided by 0.21 = about 500. Note that I’m rounding the numbers to make comparisons less complicated. If our COVID patient’s P a O 2 is 60mmHg while breathing room air, then his P/F ratio is: P a O 2 / FiO 2 or 60/0.21 = about 300. A normal P/F Ratio is ≥ 400 and equivalent to a PaO2 ≥ 80 mmHg on room air. WebFeb 6, 2024 · Normal PaO2=80-100 mm Hg. PaO2 is affected by age (tends to be lower) and altitude (tends to be lower). PaO2 and O2 sat can be related through the oxygen-hemoglobin dissocation curve! See this table for PaO2 to O2 sat conversion. Remember that from first year of med school? Straight from Wikipedia
