I started looking into mouth taping and ended up here. The more I think about it, I probably would not tolerate mouth taping even if it would help. My original sleep study had me at 14 AHI average. My device regularly records 6-60 AHI during the night for an average of 15-30 each night.
I have P30i nasal pillows and have not tolerated a full face mask.
I'm attempting to submit two pictures of my Oscar data for review. The 26OCT (23 AHI) is before I edited settings (7-15 pressure) and 1NOV (15 AHI) is after I changed to 9-15 pressure as well as tried editing my mask type which seemed to change my settings to 9-10 pressure according to the data.
I haven't slept well in a long time so I'll try any suggestions or science experiments. I selected two days I got a fair amount of sleep. The other days were around 2-4 hours.
Can you post your original sleep study? Did you have Central during your sleep study.
Did you do a titration in a lab?
I would like to see some OSCAR close up of centrals. (Clear Airway) I do not think they are all triggered from high pressure, because at the higher min pressure of 9 cm, the AHI is about 5 less for Clear Airway.
Some OSCAR closeups of Periodic Breathing as well.
I am wondering how much of the events are while you are awake.
Can you sleep with the AFlex off, if not try it at 1.
I suggest you leave Min at 9 cm, at the same time lower AFlex. I am hoping that keeps you asleep for longer intervals and have less events.
With a [3. Baseline oxygenation 93%] do you have heart or lung diseases?
Not to scare you, just for you to check your health with doctors.
Periodic Breathing may signify heart issues.
I can't tell if you were sleeping or not, the second reminds me of Cheyne-Stokes respiration. But I cant tell. I similar looking events with my new VAuto but disappeared an increase of pressure support.
No heart or lung diseases that I’ve been made aware of and I have a physical yearly. I’ve had an echocardiogram in the last year.
It could have been due to an injury. I can look into an oxygen meter to replicate the results.
I had the same concern about Cheyne-Stokes but wanted someone else to review. My most recent data after the changes has me at 3.5 and 7.6 AHI.
7 and 11 Periodic breathing events respectively. I went over my older data and see 10-25% periodic breathing on average.

RE: Looking for suggestions. 3yrs CPAP 15-30 AHI
flushed,
Don't include the calendar in the OSCAR scans, cause it may hide info.
The pressure never went to 15 cm which is what you set. If you double click on the Y axis of the pressure graph the scale may change to show that pressure did not max out.
I am not familiar with the Dreamstation 2 Autoset Advanced. The leak graph looks like you have two pressures going as if on xFlex, yet most of the time the two pressure curves almost on top each other. I doubt that can cause a 30 L/min difference in leakage.
Nov 8 the min at 10 cm. You had clearway and OA Nov 6 Min at 10 OA
Do you start on your side then go on your back?
The way that there is a lot more events later half of the night, may be that you are on your back and/or you go into a heavier sleep and there is more airway obstruction. When at the 11 cm has more events later does that coincide with medication leaving body.
Can you post this one: AHI 12.58, 12.32% periodic breathing, an hour +/- maxed pressure, 6.02 OA, 5.22 CA, 1.34 hypopena, 0.54 Rera.
I know that on Nov 8 the highest pressure reached was 12 but the OA was 5 something.
I suggest you increase the pressure again to 12 cm. and post tomorrow. Some of your max is 14 cm.
