From reading this board, it sounds like most people using oxygen are using it directly from a tank via a mask. I was prescribed an oxygen concentrator delivered through a nosepiece at 7 litres/min. I can crank it up to between 8-9 litres/min. It does not seem to be as efficient as getting it directly through a mask though. From what I have read here, 14litres/min is more like what you need. I use what I have and it helps if I catch it early but it does not seem to work as well this cycle. Does anyone else use one of these concentrators as opposed to a tank and mask?
Thanks, Robert

I believe most use 02 delivered at 15 lpm to 25 lpm now.  It is also imperative to use a non-rebreather mask:  the "oxygen info" button on the left will take you to a site where you can purchase a great mask to help abort the CH attack (a 3 litre bag is more effective than the smaller ones usually provided with the NRB masks provided by med supply companies). 

I do not think the concentrators can produce a high enough flow rate to quickly/effectively abort a CH attack, but others more knowledgeable will respond, I'm sure.

As the bbz already pointed out, most O2 concentrators produce 96% oxygen at their "normal" flow rate of around 5 LPM. When you crank them up higher, the concentration drops - often below 90%.

It wouldn't hurt to buy a good mask now and try it with your concentrator because you will need one anyway!  There are several good mask kits out there and I happen to like this kit very much:
