I've recently embarked on my CPAP journey to treat my UARS
My main issue from my sleep test was expereiencing high number of RERAs, about 40 times an hour (wich on dont remember). following the results of a split-night sleep study, my docotor diagnosed my with UARS and prescribed CPAP with a pressure setting of around 10 ramp 8 and max pressure 20.
last night was the first time i managed to sleep more then three hours with the CPAP, but i woke up feeling even more tired then i use to be. i noticied some central sleep apnea and flow limitations on OSCAR i would like to know if i should be concerned about these and what can i do to improve it ?
I would try 2 things and First you have a little bit of Positional apnea. You can see positional apnea where either H or Oa events are clustered together. Getting rid of as many as you can will lower your AHI. Positional apnea can NOT be controlled by pressure changes. You have to find out what position you are getting into and cutting off your own airway. Have you changed your sleep position? Sleeping on your back? Using more (or new) pillows? These things can cause positional apnea by chin dropping to your sternum and cutting your airway. Think of it of a kinked hose – nothing can get through – you have to unkink the hose…
IF you can’t make a simple change like changing to a flatter pillow helps then you will need a collar. I have a link to collars in my signature at the bottom of the page. It shows people who are not wearing a collar and the SAME person wearing a collar. There is a huge difference between the two.
Second I would try for a night turning on the EPR full time and set to 3.
Post tomorrow and tell us if this was better for you.
Depending on the wedge, it could possibly cause you to chin tuck even on your side. I use an adjustable bed, but only elevate it around 4". If your wedge is too tall, it could cause you to chin tuck.
When sleeping on your side though, you need a supportive pillow that helps align your head and neck. A flatter pillow works best for back sleeping.

here is my OSCAR result from last night, I increased EPR to 2 and i didn't sleep on my wedge pillow and I dont think i got my chin tuck. I'm confused about what should i look for in my OSCAR result ? cause my AHI is low my flow limitation look not that bad if i undstand ? how can i detect arousal with the flow rate patern ? cause when I wake up i still fill like i didn't sleep i'm really dizzy and tired.
I also already ordered a cerival collar following your guide, thank you for helping
You did much better with the Positional apnea. Unless some of the central were misidentified you did not have any. Did you have centrals during your sleep study?" If not you probably have treatment emergent centals which will get lower as your body gets use to the therapy.
I'm wondering if it would not be better to change from APAP to CPAP and rise the minimal pressure ? cause if I understand the CPAP will raise the pressure once he saw a flow limitation wich mean a RERA might happen before the CPAP raise the pressure ?
Here is my data from last night, I increased min pressure from 10 to 11.80 and ERP from 2 to 3 to see if it would eliminate the arousal and male me feel better but I feel worst this morning probably cause i got some aerophagia last night so i think i will reduce the min pressure to 10.5 maybe tonight and slowly increase to see at wich point i got aerophagia

Hi SleepyGin, I would lower your max pressure to 14cm and disable ramp completely just to be safe here-as one of our other posters suggested I would try cpap mode as well to see how you feel regarding comfort levels.
If you would like to try it, I would set it to 13cm CPAP mode (or 13cm min/13cm max) with EPR set to 2-ramp disabled).
