Wondering if anyone uses a BIPAP machine and if it helps their sleep? or if anyone had problems with it? Also wondering how noisy they are as i don't want it to affect my partner's sleep. And if anyone can recommend a model that would be great. I've just been told i have mild sleep apnea. This is based on giving a sleep study kit home for one night's sleep. I don't know whether to trust that it's mild because my sleep quality fluctuates and i didn't have a particularly bad sleep that night.
