Find actual percentage of O2 on Non-Blended Low Flow Nasal Cannula Here!
Simply input the child's weight (in kg), his or her respiratory rate, the current O2 flow rate and percent O2 at the blender.
Calculator Algorithm:
FiO2 = ((F x (B - 21) / 100)+(0.21 x R x W x 5.5)) / (R x W x 0.055)
The equation has four variables: weight in kg (W) , respiratory rate (R), gasflow (F) and percentage of oxygen in the gas (B).
A tidal volume of 5.5mL/kg is assumed.
