I wanted to add an Update for others so they have info to help them with their Xpap struggles.
Short story, a new mask made a big difference. I knew that a mask can feel ok but not be ok (raise AHI), so it can be hard to know if there is a mask issue... I wanted to give things a good try (adjusting pressure, mask fit, having both an SD card and a Oximeter and Somnopose to gather more info) since I am a new user and I know several things can impact good Apap therapy - before just saying it must be the mask.
The DME was not helpful in confirming/figuring out if I had a mask issue so I talked to Resmed and gave them my suspicions about the mask fit. The rep strongly agreed the mask was not fitting correct. While the charts show low levels of leak and myair gives me a happy face, they were there continually and I if the mask shifted a little (which it would while I moved around at night), I could feel a slight leak at the top and at the bottom sides. The headgear was not tight enough (Resmed said it should fit snug like a cap) and I think the mask was a little to tall and a little too wide - maybe .5" each direction.
I went back and got an AirFit F30 and not only has my O2 been better (not the crazy dips down though still not optimal), but I am no longer waking up every 10 minutes to yank my mask off my face so I can breath - that alone probably increased my sleep quality a lot. The pressure line now shows fairly steady unlike the ones I posted where it did huge drop and rises.
If a sleep score (quantity and quality) was 0 = horrid and 10 = great, I would rate it a 3 on the old mask and a 5 on the new mask, it was a huge improvement - went from miserable sleep to just bad sleep
. However, sleeping with no Apap (or mask) I typically get an 8 so I still am aiming to get at least back to that level with a machine. For now I often skip nights with the machine because several nights of poor sleep in a row is miserable. I have stronger empathy for those with sleep apnea now since experiencing those symptoms (though mine are with the Apap on).
Note: The AHI readings (or even the O2) do not match my sleep quality. For the couple times I have gotten low AHIS (1.79 for a nap one day, 3.23 for one night sleep) I still felt horrible like I had slept very poorly (tired, groggy, fuzzy head, etc.).
With the new mask my AHIs typically go from 11-16 (plus the 1.79 for the nap) where as the old mask (with the SD chip) were 3 nights of 3.23, 17.5, and 8.13. Before the SD chip, MyAir gave AHIs between 5.5 & 20) but I am not sure how accurate that was (especially since I got very high mask no leak scores when the mask was doing some leaking).
This confirms my suspicion early on (even before the SD chip) that discomfort is interrupting my sleep more than the apneas or drop in O2.
I talked to the Dr today, she said that the bad periods are likely REM sleep as that is the REM apnea sleep pattern (very bad for a shorter time). Even with the new mask, while sleeping on my back I will suddenly get a lot of apneas for about a half hour - Oscar says 40+ for that period, then they go away. Surprisingly when that period is done (not in the middle) is when I wake and want to take the mask off. Sometimes O2 drops also at least towards the end of that string of apneas. It might just be a back sleeping & REM combo that is bad for me and slide sleeping and REM works fine.
The Dr agreed I should try a BiPap so I will get one hopefully this week. And she mentioned we could also try an ASV machine though I rarely get central apneas.
Hydrangea, I tried the soft setting. I am not sure I saw a difference, I can check again with the new mask now things are better.
I haven't tried ramp because I read before sleeping and it sits around 4-6 while I read, then sometime after I fall asleep it climbs up (within about 30 minutes) to the higher level. I figure that works the same as ramp would.
Dave, I have tried that by accident for the lower number
- resetting numbers without glasses on. I will keep that in mind with the new machine - hopefully that will work to adjust numbers a little bit for fine tuning.
Hydrangea and Dave - I struggle to breath out if the exhale is 8 or above - that includes sitting up and wide awake.
I sleep better if the exhale pressure is lower (that was my first try after playing with it sitting up the first day). I tried a level 8 for inhale to try and get used to the machine at a more comfortable setting. That was with the old mask and before I had a SD card or Oximeter pulled out, so I don't know the whole story except my AHIs were high. I seem to hover around 9.5-11 at night for my max inhale pressure now. So if I could get that exhale down to a 6 I would be happy and I think I would sleep better. A bipap should do that , I hope I get back to a sleep quality level of an 8 (that I get with no machine). Then I can start fine tuning things.
