Requesting advice to try and help my brother with medical care.

A nebulizer is a great idea as well, GA. Any treatment to open his airways should be considered. A nebulizer can be ordered without a lot of paperwork and is very beneficial for many patients.

Thank you GA, appreciated. :)

Shane, what do you think about asking for a script for a nebulizer?

Buzzy, my father had to have a sleep test for oxygen sats overnight first; that started oxygen for nighttime use. Gradually he required it for daytime use, and as Shane wrote, had tests for that as well.

What we also used was a HEPA air purifier and a humidifier, both in the living room, where he spent most of his time,

You might also ask about an incentive spirometer. We've gotten ours during hospital stays, so Medicare paid for them.

Thank you all. I will check things out. :)

Contact his PCP. There are many requirements that need to be met prior to Medicare paying for oxygen. First are pulmonary function tests that must be done. Oxygen is expensive and health care providers need to submit a lot of testing and paperwork to Medicare to get it paid for - endurance testing, O2 sats, lab work. I suggest your brother get one of those puloximiters (the little device placed on the top of finger) and have him log it. He can purchase one @ CVS or another chain for about $40. O2 sat should be above 90% on room air. Ideally 95% or greater- to me 90% is too low but Medicare rules are rules.
Good luck!

Ah thank you :)

If he thinks oxygen is warranted he needs a prescription from his doctor. This is not an item that can just be bought.
