The first days of data aren't very relevant right now though and what is more important is seeing your recent 3 EPR results. Posting your OSCAR settings tab including the "Changes to Prescription Settings" section would help interpret recent averages quickly. Here is a screenshot of the section I am mentioning.
On Jan 16th you tried one day of 1 EPR at a lower pressure and you had your best results of the bunch, these results were also similar to your recent 1 EPR results.
Then you tried EPR 0 with a few pressure settings but your flow limitations (I am assuming FL but potentially could be snore, can't see the data) kept maxing out pressure so all you effectively tried was fixed pressures from 9-12 cm with 0 EPR. You suffered with leaks, 0 EPR makes it harder to breath out and you were most likely opening your mouth because it was difficult to breath out against the pressure and then leaking out mouth. AHI was mediocre (better than 3 EPR though) and I am not a fan of the flow limitations/snore driving pressure up.
Then you tried EPR 1 for a couple more nights at higher pressure (13 cm) and had moderate results (better than 3 EPR and 0 EPR data but not as good as lower pressure 1 EPR). You still had leak issues for the same reason (high exhalation pressure of 12 cm causing discomfort).
In summary your 3 EPR data is riddled with central apnea and if it hasn't improved since then you are arguably making your sleep quality worse not better with those settings. Treatment emergent central apnea can get better with time but it can take up to 6 months. You are only 2.5 months in so it is still possible it could improve but both of your sleep studies indicated central apnea without CPAP so not all of your central apnea is treatment emergent. I expect you will always have central apnea present unless you use an ASV to treat it, the question is if we can we keep it to an acceptable level without ASV. 0 EPR doesn't get along with you and 1 EPR was the golden spot in January/February and also recently. Higher pressure doesn't obviously help but 13 cm with 1 EPR wasn't as bad as I would have thought it might be. I am sticking with my previous prediction that your best results will come with a fixed pressure somewhere between 6 and 9 cm with 1 EPR. There is also a chance a small range like 6-9 cm with 1 EPR might be best but I would try slowly increasing fixed pressures first to get an idea of how your apnea responds to pressure before considering a range.
Hi Geeri,
Here the statistics chart. Please also find below my datalog from 20 Mar 2022 to 30 Mar 2022 for your review in my goggle drive https://drive.google.com/drive/folders/1...sp=sharing.
