welcome oh dizzy one.
ok - I think we owe it to you to speak up about your CPAP trial and use of settings and stuff.
first - yes, they can tell if you made settings and then adjusted them back. The data card stores that and so does the machine without the data card. there is no way to do the study and trick them.
second - and I know you won't like this - you should be off CPAP for a couple days, maybe 3 to 4, before strapping up their device. The longer you self-treat, the more likely it is that you'll score well. The object is to prove you score badly. I hope you see the inverted logic.
Dedicated to QALity sleep.
You'll note I am listed as an Advisory Member. I am honored to be listed as such. See the fine print - Advisory Members as a group provide advice and suggestions to Apnea Board administrators and staff concerning Apnea Board operation and administrative policies. Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment.
Just checked my sleep study report and my Central Apneas were only 0.3 per hour.
There is no mention of any pressure settings for cpap.
