Central Sleep Apnea, Anyone try supplemental O2 via nasal canula

Thanks for the reply. I don't know whats going on, and so far am not very happy with the treatments provided. They seem to be just throwing things at the wall, try this, if it doesn't work then we will try something else. right now using a Resmed set at fixed 10-14 pressure setting.
higher setting priviously with auto setting was not good. waiting for them to eval the new data from the WatchPat One I did at home. I think they are looking for restless leg or periodic Leg movements, and possible medication.
Any way thanks for you evaluation. I think its something with the feedback loop and
CO2 and O2 and shallow breathing. I can be awake and just relaxing and breathing at 25-30 breaths a minute and watch the O2 go down with each breath from 98 to 88 and then back up at the just short of 1 minute cycle.
again. thanks for you evaluation. I will provide more data when I get data.
As an scientist and engineer, I am looking for an explanation and then a suggested treatment that makes sense instead of just try this, try that, etc.

I am a retired Chem. Eng. , age 80, with identical issues. Could not tolerate CPAC due to difficulty exhaling against pressure. Will be trialing bi-level , at sleep Docs advice, but he has discounted good evidence issue is primarily central.
After CPAC fail and waiting to figure out next steps I bought supplemental generator ($US300). I wear Wellue ring and have since starting down the apnea avenue so I could watch what was happening.
I also have PVC (premature ventricular contractions) and some Cheyenne Stokes breathing pattern. Cardiologist checks (stress, echocardiogram) show heart is fine so far.
Lateral sleeping, using 500 mg Quinine and breathing strips (deviated septum) while using 2 litres/min of 78% O2 is delivering fantastic results. Under 5 /hr. over 4%, drops. Some nights as low as 0.2 drops/hr. O2 mostly between 95-99%, seldom any under 90%.
I shallow breath but the O2 gets in enough to stop the loop gain problem.
I consider my problem under control (my blood has lots of O2 all night) but I will still do the bilevel trial primarily to learn more.
$300 O2 concentrator vs. $2500+ irritating uncomfortable bi-level (or worse, servo) seems a better solution for my situation.
Happy to share more once I am ok in this site, if helpful.
Good luck
