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)

Oxygen Delivery Systems. Continuous flow. This system delivers a continuous flow of oxygen from the storage container. It is a very economical system in that it doesn’t need complicated masks or regulators to function. But it is also very wasteful—the flow of oxygen is constant whether you’re inhaling, exhaling, or pausing in between breaths.
