High Flow Calculations - WordPress

Oxygen Flow Formula •This formula lets you determine the oxygen flow to set if you have a target total flow and target FiO2. –An example of this is an entrainment device. •Oxygen flow = (total flow) x (FiO2 –0.21) 0.79* •The 0.79 comes from the percentage of the FiO2 that is not accounted for by the oxygen in air (i.e. 1.00 –0.21)
