Hi,
You may want to try out sleep pro as it will help you breathe naturally better, also because you can do it at home yourself.
Hello,
You should ask your sleep specialist for a cpap with a humidifier attached to the main device. And if you use oxygen alongside that should also be humidified. That should help a lot. A Sleep Pro device usually helps in patients with snoring so its benefit in the condition you have described is questionable. But you could still suggest it to your sleep specialist and see what he has to say about it.
