Oxygen %

If it's pure oxygen, it will be 100%, regardless of flow rate.

<...the actual stuff the patient is breathing may well be much less than that...>

If a patient is breathing it, then it will be "oxygen-enriched air", which still has nitrogen, argon and some other stuff in it. Breathing pure oxygen at normal temperatures and pressures makes the skin go red.

Do you mean for breathing in a hospital or similar situation?
If so, then AFAIK it's not 100% .It would be set to a very low flow into a mask which is also open to the atmosphere to allow a mixture of air and oxygen.
Wiki is quite informative on the subject, suggesting that it depends on the situation and may also be adusted on the basis of levels of O2 in the blood.

24-44% 1-6 LPM

Thanks SolarEagle...Much appreciated...

I don't know whether you birds of prey have a secret language , but I'd agree with other posters that there's not enough information to tell what you're asking.

Thanks, now I know!

Room air is 20.9% O2 @ 2LPM...which is the saturation leval of O2 in room air we breath..the air you breath from an O2 bottle also has a saturation leval based on how many liters per minute you set it to and that is the info I was looking for and the answer he supplied, and by his answer he understood the application as well....screech...screech.....

That's right, the % by volume of O2 in normal air is 20.9. But how is that a "saturation level"? Water saturated with air contains dissolved gases varying with the partial pressure and solubility of each, but there's no reference to solution.

Sounds like the 1 - 6 LPM is being mixed into a fixed flow of air, but without knowing that it was hard to comment. Incidentally, from a quick calc on 24-44% 1-6 LPM, I don't get the same air flow for 24%, 1 LPM and 44%, 6 LPM, but maybe I'm missing something.

It's 24-44% for each increment of per litre flow, so that if you determine 24% at 1 LPM and 44% at 6 LPM then you have the full range needed..

Interesting thread dynamic. GA for #4

And to think, I'm supposed to know this stuff
