I have an inogen, it only goes to 6.

Hi Marge 6, I don’t have a portable concentrator. It’s a home one that goes to 10 liters and is continuous flow.

Hi Kathy, Is your 6 liter continuous flow or pulse. Most of the portables are pulse. The new one I got is a Sequal 5 and on pulse it goes up to 9. That was the only one I found. Its a concentrator on wheels and weighs about 18 lbs. I purchased an extra battery with it so I can take that out with me if need. It also has a car charger and a wall plug in.

I checked because I’m on 6 liters and they don’t have them. So I have to lug around those awful old green tanks. I hate that. We have to carry so many cause 6 liters last about 15 minutes. I’m getting to where I don’t want to go out because it’s such a hassle. Praying Winrevair/Sotercept gets my oxygen level lower.

I’m not aware of any that go above 5….
