2 Formula •This formula takes known oxygen and air flows and calculates the FiO 2. •FiO 2 = (Air flow x 0.21) + (Oxygen flow x 1.0) Total Flow •Note: –Air flow and oxygen flow must use the same units –Remember that the oxygen in room air contributes to the FiO 2 as well! This will help you remember the formula.

How many oxygen cylinders do you need to take on transport ...

Oxygen consumption was calculated at different rates (fig 1 1)) and plotted against duration of usage (for example, line y = 660x represents 11 l/m flow×60 min×hours used, while line y = 300x represents 5 l/m flow×60 min×hours used). The x axis represents the estimated total journey time (hours); the left hand y axis represents oxygen requirements (litres) and the right hand y axis the ...
