The last time I visited my sleep therapist, she lowered the pressure on my apap a few notches. I wondered how much I'd have to lose to lower it even more.
CPAP pressure settings are pretty cut and dry: you give it enough pressure to relieve your apnea. You don't want it any higher than that because more pressure can lead to more pain in your sinuses and making it harder to wear your mask every night. So it's kind of a judgement call about exactly what pressure to use.
My APAP has a range of pressure, say 9 to 12, and this is adjustable. It puts out a pressure between 9 and 12 depending on how much I need on that particular inhalation or exhalation. It's all working quite well and I don't want to tinker with it.
Still, as I continue to lose weight, I'll go in to have the setting adjusted lower. The therapist thought the settings should be changed with a gain or loss of about 20 pounds. I think I'll be ready for a re-adjustment pretty soon.
