I did a search, not that means much, and cannot find any discussion of anyone tethered to oxygen. It is really an annoyance. No point. Just a rant.
Hello, you are not alone. I also use oxygen twenty four-seven. I have an electric scooter that has a basket on the front so I can carry my small tanks of oxygen with me. works great. I can go around my flower gardens and yard with no trouble. They are pricey but worth it. I always carry my cell phone with me incase I have trouble. I don't go out unless my husband is close by. I can reach to do some weeding, etc. from my scooter or by reaching as I have a fairly long hose on my tank. Hope this helps.
