The comparison chart is what you really need to look at. It will show you everything you need to know about POCs. Ryan Diesem is the absolute expert on POCs and what each one will do. Everything he writes about has been tested by him or comes straight from the manufacturer.

Don't be fooled by the settings; they don't begin to equate to anything on your standard stationary concentrator. The most that any of the lightweight POCs will provide is 1.26 LPM and that's on a setting of 6 with an Inogen 5. At a setting of 1, you get something like .2 LPM if that.

I am one of those people, @A MyCOPDTeam Member, as I was an advocate for the COPD Foundation’s activities in 2020 and 2021, and it’s just frustrating that medicare’s refusal to cover = lower quality of life for many people.

Just FYI: there's a group of patients, advocates, health professionals, and people from ALA and the COPD Foundation who are working to get data CMS has requested in hopes that we can get liquid O2 back. In the process we are compiling a lot of information that we plan to give to legislators in hope that they'll make legislative changes that will encourage use of Liquid for all patients who need O2. I don't know that we'll be successful, but we're working hard on trying!

As far as I know the only continuous flow concentrator is a large home unit. Haven't developed a portable continuous flow unit as yet.

@CarriBraley yep those portables going up to 6 is good ole deception in my opinion, because 6 pulse is about equal to 1.2 lpm of continuous, when i set a portable at 6 lpm the expensive battery depletes rapidly. I carry a small bottle of regular oxygen as a backup when walking because the liquid valve freezes up on very rare occasions.
