Just google Fick principle. It will give you the calculation method.
Is this for confined space?

100 BPM is heart rate at rest so O2 consumption would approximate 3 Litres per min or 4.29 grams based on 15 LPM of air.
If we are talking BA us, the duration of AIR is based on a notional average of 40 LPM but this can rise to 100 LPM depending on work rate, environment and fitness of the wearer.
Duration is calculated as
D (minutes) = (P (bar) x C (litres) / N (bar) x 40 LPM) - 10 minutes
so duration of 1800 litre cylinder at 200 bar
(200* 1800 / 200*40) -10 = 35 minutes

If it is for confined space or any other BA work, its air consumption you will be after, not Oxygen, as thats what your cylinder will be charged with.
