Calculates the Fraction of Inspired Oxygen (FIO2) using the flow rate of Oxygen in L/Min.
Formula:
FIO2 = Percentage of atmospheric oxygen (20%) + (4 x Flow rate in L/Min)
Principle:
The percentage calculation of oxygen received by a given flow cannot be precise every time, but relatively accurate estimation can be obtained by relying on some guidelines.
The percentage is indicated by comparing FiO2, a fraction of inspired oxygen in the air, to a transportable oxygen device. We can gauge effective FiO2 under normal conditions through a general rule of thumb.
