OSCAR Data from a few nights

Thanks to some very kind folks on here, I've been able to try out a couple of masks - Dreamwear and F20 Air Touch (still seeing which one works best) to gather some data from OSCAR. I only able to wear a mask for 4-6 hours before I end up taking it off because the air pressure, a leak, or the mask itself will disturb my sleep. Though, I'm definitely finding more comfort in the masks then my previous Mirage Quattro. Hopefully I'll get more use to it if apena is actually my issue.

I'm trying to determine if apnea is the cause of my fatigue or possibly something else. Something that stood out to me are the number of clear away (central apena) events as that was not mentioned on my sleep study report. That has me wondering if the APAP machine is causing them or they are false reporting. Side note - i feel like the nights I used the APAP, i've been more tired than usual - maybe that's because of sleep disruptions or maybe there is not a need for APAP therapy.

As mentioned from my sleep study:
-AHI 4.6
-AHI during REM 13.6
-Sleep efficiency 67.5%
-Sleep spent in rem 22.7%
-REM latency of 165 minutes
-No significant PLMD
-61 spontaneous arousals which equates to 10.4 per hour
-patient experienced 6 apneas in total - of these, 6 were obstructive apneas, 0 were mixed apneas, 0 were central apenas. Resulted in an apnea index of 1.0
-patient experienced 21 hypopneas in total which resulted in a hypopnea index of 3.6
-AHI results by body-position showed: supine AHI=2.4, right-side AHI=N/A, left-side AH=9.8, and prone AHI=N/A
-0 occurrences of Cheyne Stokes breathing, and 0 respiratory effort-related arousals (RERAs)
-mean SpO2 of 97.3%, minimum SpO2 of 94.0%

Doctor recommended trying an oral appliance or sleeping on my side and to followup which is scheduled in a few days.

I experimented with the pressure some nights, with the latest report, dropping it to a low 4-5, but still noticing central apena events. They may not all be actual true events as from some research i've done, it appears I could have been awake during some of them. One of the centrals was recorded for 30 seconds which was surprising.

None the less, here are more screenshots than are probably needed.

To me the only event that looks like you might have been asleep when flagged was the central at around 01:50.
All the other events you zoomed in on look like they were related to an arousal...now what caused the arousals is a totally different question.

Your spontaneous arousal numbers...that means not related to any airway issues...crappy sleep but crappy for some other reason than sleep disordered breathing.

If you couldn't see these reports...how would you rate your sleep quality? How do you feel during the day?
You can continue to try to work with limiting mask leaks as a potential culprit for causing arousals and see if the arousals reduce.

You might also take a stroll through the entire flow rate (not just where flags are shown) to look for irregular breathing which might point to an arousal that didn't caused enough irregularity to earn a flag of some sort. See how many of those you see....most likely they are going to be spontaneous in nature. If you have a lot of them very likely will explain not sleeping so great and not feeling so great.
I have done this myself...and seen maybe 30 to 40 of them...most likely related to pain in my situation. Lots of tossing and turning in bed secondary to back/pelvis pain. Usually feel like crap the next day when that happens. Bad sleep but totally unrelated to any airway issues and instead related to pain issues causing arousals that I may or may not remember.

I didn't get a chance to look at your last segments but I will try to do that later. Short on time at the moment.

Everyday is a struggle with fatigue and sleepiness. Some days are not too bad (very few days). Most days feel like I’ve been hit by a train and wake up completely exhausted and drag throughout the whole day until I repeat the vicious cycle for the next day. Each year it seems my sleepiness, mental fog, lethargy, daily headaches, and concentration have seemed to worsen.

I’ve been trying to figure out what’s going on with all the arousals so I set up a camera to record my sleep and see if I uncover anything. I’ve noticed it seems I wake every 4-12 minutes, depending on the night, and the arousals usually follow the same pattern - I seem to stretch my legs or back, let out a loud sigh, and change positions. Something to note, a second before about half of the arousals I have a slight snore or a quiet “pop” sound from my mouth. Hard to describe the noise - almost as if my breathing gets barely obstructed and I wake up the second it begins to happen. It’s hard to verify or be sure. The other half of the arousals are a combination of me scratching an itch and unknown mysterious reasons.

Now I am not saying that you have this but you might want to research it a bit and see if you fit the bill.

Thank you for your insight and leading me to that. It definitely seems that could be what I’m dealing with. The thing that throws a wrench in it is the zero number of RERAs I had on the sleep study. I’ll mention this at my follow up appointment next week.
