Do you know how many liters/minute you need to stay saturated? The POC that provides the greatest flow rate only delivers 3 liters/minute continuous flow. If you need more than that, you need to use a larger concentrator with tubing, larger tanks (with a cart) or if you can, liquid oxygen. It’s increasingly difficult to get liquid oxygen but there are a few places in the US where it is possible. Sorry, those are the only options and can be explored with your physician and medical team.

The SOAR ACT is trying to make liquid oxygen more available. More info is in this link. https://www.runningonair.net/soar-act

This act is being re-introduced this year and seeking co-sponsors. Please reach out to your Congress persons and urge them to support it!
