There are electric stationary concentrators that go to 10 LPM. You can get regulators for tanks that also go to 10 LPM, but tanks don't last long when used at high LPMs. There is no small (less than 10 pounds) portable oxygen concentrator that produces more than 1.26 LPM. It doesn't matter what the settings are; they're just numbers. A setting of 5 or 6 will produce a very small amount of 02 for each breath with the pulse dose delivery.

Go to www,runningonair.net/oxygen for a list of FAA approved POCs with all the information you need about how much 02 the machines actually produce.

I have finally quit after 50+ years with Nicotine anonymous...I have 15+ months nicotine free!!! Never thought I could do it ....meetings are online on Zoom ...people are understanding and if you relapse they understand....most of the ones I go to are in Los Angeles online cause I live in San Jose California....There are meeting in the Eastern time zone, the UK, and Washington, you will have the choice.. Good luck ....Fran Friedman

Doctor told me I could get lung reduction surgery but as I can't totally quit smoking, I am not eligible. So my next is probably the end. I have had rough life and good times as well so no regrets.

I'm there already..
