Yes I do! Love it for portability and it really helps with my walking. I use it when I have to do my minute walk test and do my walks up and down my street. Yu will want to work with the rep that comes to your home and make sure to get your settings correct! I've had it for about 9 months now. The o2 flow is a variant. When I start breathing harder it seems to sense and increase the oxygen flow. I've seen it as high as 5.6 ltr pm and down to 1.5. in the middle setting. When at rest I switch it to setting 1 or sleep position as my breathing slows down. The rep can help with these settings to fit your needs.

First of all, your Freestyle only delivers 1.05LPM. The setting of 5 is just that; it does NOT mean that you're getting 5 LPM. You aren't. You're only getting 1.05 LPM by pulse dose over a minute. That's something to think about.

The backpack is the 02 tank that is required by the Ventilator. I don't believe it will work with any other 02 source. Check with the supplier or the manufacturer to be sure, but I believe that is the case.

I invite you to visit my page. I posted some photos from the Life Share Oklahoma flag raising in April. I am using my life 2000 with an E tank of O2. I use a C tank sling bag to carry the life 2000 unit along with other stuff.
