Newbie Needs Help with Pressure - sleepypilot - 08-17-2024
Howdy y'all:
newbie here in need of help. I recently got an Airsense 11 following a sleep study that showed that I have mild OSA when supine and in REM. The doctor had my pressure set to 5-15.
I started looking at changing my pressure as I would get woken up in the middle of the night with this uncomfortable air bubble sensation in my eye. After doing some research it seems like I have LDAR. I went to my clinician and she had me try 5-10, with a full-time EPR of 3, which stopped the LDAR, but decreased the quality of therapy. It felt better than before CPAP, but worse than when I was 5-15 with EPR ramp only. 5-15 leaves me feeling well-rested, with a substantial difference compared to before therapy, however I wonder if there is room for improvement.
I switched it back, but the eye sensation is present again. I have been reading up on minimum pressure and wonder if my range is too broad. I downloaded OSCAR, but am not sure if I am looking at all the right things....from what I can discern maybe my pressure should be something like 7-12?? I have played around with other pressure variations....didn't feel well-rested compared to the 5-15. Perhaps the 12 will stop the LDAR and the increase from 5 to 7 will help prevent events?
Thanks!

Part of the conflict is Ramp of 4 with you starting at min pressure 5. Consider no Ramp. It shouldn't be necessary at this low level.
Second and third conflicts:
The pressure Min 5 EPR 3, it can't do EPR until pressure increased to 7. It's physically impossible to have EPR reduce below 4, the physical low threshold of your CPAP. You probably need to start at 7 min.
Your EPR is Ramp only. Make it full time.

Most of the pressure jump are from something other than "events". The pressure hikes are correlated with the higher flow limitation. The posted chart only has excursions up to just shy of 11.0. Getting used to EPR for you may be a challenge, so start slow. I would try min at 7 and max at 12, EPR full time, and EPR set at 1. This should not feel much different that you most recent nights. I would use the new settings for at least 3 days before deducing any meaning to the scores. If you get a positive feeling and see any reduction of flow limitations and pressure spikes, you can always increase the EPR to 2, again for a few days straight.
