There is a wealth of information there...i think it will take awhile to begin to understand it. Maybe this weekend i can take some time and delve into a good tutorial.
I did look at the minute ventilation you mentioned, and mine seems to average on 5(5.05) with some fluctuation up and down.
With the changes i made last night the pressure did go almost to the 11 number of times... but seemed to be around 9 most of the time. So the 10 they prescribed years ago still seems to be pretty close. I think i will leave these settings for about a week and see how i do. If i push the top much i may increase the max to 12 to see if 11 is enough. The AHI was 0.3 last night... so all good there.
I have not had a full blown sleep study since 2007. They tried this year but i never slept deep enough to have any issues. I think i should have had a drug first since they wanted two hours deep sleep without my cpap. After 17 years use, that is difficult. They then did the home study, and did give me drug... so at least they were able to confirm the severe apnea.
Most importantly, all the other items are still good today... so going back to the old mask seems to have solved those problems. Had i faced those issues when i first went on cpap, i never would have been compliant... it was miserable!
