WebNov 3, 2024 · OVERVIEW. PaO2/FiO2 ratio is the ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen (FiO2 expressed as a fraction, not a percentage) also known as the Horowitz index, the Carrico index, and (most conveniently) the P/F ratio. at sea level, the normal PaO2/FiO2 ratio is ~ 400-500 mmHg (~55-65 kPa) WebMay 2, 2012 · He adds, “With air fuel combustion you typically have a 10 to 1 fuel ratio, but with oxy-fuel it is only 2 to 1.” ... and operators are attracted to the higher combustion efficiency offered by burning natural gas with oxygen. These potential energy savings are quite variable, and depend on the type of furnace, the type of burner, and the ...
