Added Wellvu Ring O2 to the arsenal

Added Wellvu Ring O2 to the arsenal
   

Have been lurking here for a while. Hope you guys have some advise for me.
My experience with Sleep Apnea has been somewhat uncommon (I think). 

Prologue
  • Diagnosis - Was diagnosed 5 years ago, AHI 6, RDI 14, and was prescribed Resmed A10 in US.
  • Symptoms - loud snoring, day time tiredness, fatigue, brain fog, etc. But I wasn't sure if SA is the culprit or anything else.
  • Took a long time adjusting to the machine. Finally settled on nasal pillows. Started using the machine 95%+ times.
  • But never felt much improvement in the symptoms (had some small improvement). Sometimes, I felt better, but most of the time, I felt like sh*t when waking up. Took 1 hour or more to be able to leave the bed. 
  • Did a self study with Resmed in 2019, in India, and this time AHI was 21. 
  • If I tried to stop using CPAP I couldn't even fall asleep as the tongue would fall back choking m eeven before I could sleep.
  • Did another sleep study in US in 2020. The study went wrong as they messed somethings up but it still confirmed that I have OSA, and must use CPAP. Ruled out other common issues like narcolepsy, positional SA, very small CSA.
With this background, I decided to study my OSA with more data. So I purchased Wellvu Ring O2. It is recommended in this forum and my research indicated that it is close enough to medical grade for my purposes.
Last night, I took my first reading (after some sanity tests on the ring). No CPAP, just Ring O2. This morning, I was only slightly more tired than usual (as I didn't use CPAP). But that was not the biggest surprise.

Surprise


O2 Ring shows that my sleep was very good! I know, SpO2 cannot be used to diagnose SA, but I was expecting that I will have a high number of OSA events which would show a corresponding drop in SpO2. But that is not the case.
So when I put everything together, the only conclusion I can draw is that at least in my case, even though I have mild OSA, it is not accompanied by a drop in SpO2, and even though I do not see a major benefit or relief from symptoms, I must keep using CPAP on blind faith that somehow it must be doing good.
This is fine, but its just a bit demoralizing for my enquiring brain.

Next
I will take a few more measurements with and without CPAP machines. But would like to see what you folks think.

You could use OSCAR as Sleepyhead isn't supported. Then post a chart. Looking at the data by those that know how to interpret would help you. SpO2 data is only helpful to a certain degree in predicting Apnea.

Sure, adding a few screenshots. But please note that my subjective experience doesn't match the AHI reported by the machine.

If your not using one yet, your showing some Apnea clusters or AKA positional Apnea. See the cluster of blue ticks from around 0000-0130? Likely your chin is tucking down towards your chest, kinking the airway and creating a restriction that sets up a string of Apnea as seen here. Look at the soft collar and the positional Apnea wiki in my signature.
