Lawilson, for cofort levels, might I suggest Pursed Lip Breathing techniques, along with what Gardenartist recommend above. Google this, as it may help to get more O2 stores in the bloodstream, plus make her more comfortable, when she is breathless after walking ns moving around. The inability to breathe is such a terrifying thing!
She definitely needs to be under the care of a Pulmonolgist, and have all of those more indepth tests done, inpatient onvernight, ifpossible! You might have to put your foot down a little, while requesting them!
It sounds to me like you're on Medicare. Sadly, your situation is not the first I ever heard where are Medicare won't cover something that someone needs. You can get a supplemental insurance or just ditch Medicare altogether and go with an alternate. You can look into Medicaid and see if you qualify, but you may also face the same issue unless your doctor can do the paperwork. If not, I would just go with an alternative insurance company and maybe even get two or three others if you can afford it. See which insurance companies cover what and go from there, you shouldn't have to pay for expensive oxygen out of your own pocket
