Except its the Concentrator with Non Rebreather mask,,, they said they could order me a M60 which I will have them do,,, how long will a m60 tank last at 15 lpm say 10 min sessions?

At least for now I'll have something even if its the concentrator which people say  doesn't work,,who knows maybe it will work for me

Thanks Chad ,,,I'm not far from you ,,Limerick,Pa

When an attack comes it is most effectively killed by breathing fast enough to cause hyperventilation.  You know when you were a kid and you would have competitions with your friends to see who could breathe fast enough to make themselves dizzy?  That's what I'm talking about.

What's that?  You didn't do that as a kid?  Ok, I guess I was just a stange kid 

This is how it works for me...

At 15lpm I can't hyperventilate.  However I can at 25lpm.  You only need to do this for five minutes or so.  It will kill the pain.  Then stay on for another 5-10 minutes at a lower rate, say 15lpm, to make sure it stays gone.

Anyway, this is what works for me and many others.  Some folks are able to abort fine with as little as 8lpm.  Some use as much as 60lpm or even demand valves where there is no upper limit.  We're all unique in what works and what doesn't so you have to experiment to find what works for you.

With a concentrator, it takes a while for the machine to begin making 100% O2.  It generally starts somewhere around 85% O2.  Those early minutes count.

What Pete (a.k.a Batch) is proposing is to rig up a 40gal trash bag and keep it filled with O2 at all times (I believe) by constantly running the concentrator.  This should give you enough pure O2 to abort a hit without having to wait for the machine to come up to speed or suffer through with a low flow rate.

Personally, I think it's a brilliant solution.
