Oxygen in air formula
Web12.8.1 Stoichiometric Conditions. Stoichiometric air or theoretical air is the exact amount of air required to provide the right amount of oxygen for complete combustion. The amount of air required for stoichiometric combustion is fairly constant on the air/gas weight ratio, with an approximate value of 16. WebAug 11, 2024 · How to Calculate the P/F Ratio: PaO2 / FIO2 “P” represents PaO 2 (arterial pO2) from the ABG. “F” represents the FIO 2 – the fraction (percent) of inspired oxygen that the patient is receiving expressed as a decimal (40% oxygen = FIO 2 of 0.40). P divided by F = P/F ratio. Example: PaO 2 = 90 on 40% oxygen (FIO 2 = 0.40): 90 / 0.40 = P/F ratio = 225. …
