Oxygen in General Board Posted Monday at 06:02 PM · Report reply 3 hours ago, clovis fick said: I dont understand what that means, bag? The "redneck" method that I mentioned and linked to above involves filling a kitchen garbage bag with O2 and using that along with room-air hyperventilation. If your oxygen supplier is going to honor a sensibly-written prescription, which should have specified that it's for CH and that the flow rate should be at least 12 lpm and you should get a nonrebreather mask, then they ought to supply you with a larger tank. TBH, I seriously doubt that that is all they have (not doubting that they told you that), but if it is, they are required to either replace your tanks as often as necessary or get you a larger tank. If your doctor is sympathetic, get him/her involved. O2 suppliers are regulated by most states, and I believe they are breaching their responsibility to you. You might not want to go there (larger tank(s)/reliable refills) because the cost might be too high.
