Why????
Everyone has different metabolic rates of cellular respiration, different heart rates, different breathing rates, different breathing air volumes, different blood volumes, different blood oxygen capacities, etc..
Which of course vary constantly with metabolic load AND stress levels.

It is true that I have spent a lot of time using a “breathing for minimum heart rate with exertion held constant” technique to help me breath with the most efficient (best metabolism) blood gas levels. So perhaps the fact that I have repeated the experiment more than ten times and got the same results is true only for me.
Still my oxygen levels dropped like a stone at night using my pulse oximeter but not my CPAP. At night, in bed. Not running the mile. Not even walking up hill. Not even sitting in my chair as I did for the experiments mentioned above but at rest in bed.

I just mentioned a few of those.

That was well covered in the referenced article.

?? Where does this come from ??

I have little interest in how special or not I may be. I am very interested in finding the actual cause(s) of Obstructive Sleep Apnea so we can start working on a real cure instead of these silly, crazy, does not work to well mechanical splints called xPAP therapy.
In terms of connecting with research and research I would love to see – working on it!!!

All I am doing here is to point out that the bodies reaction to the constant strangling presented to it by the constant cutting off or at least notable reduction in air flow (from the standpoint of the person experiencing that reduction) is a hugh part of what happens in Upper Airway Resistance Syndrome and Obstructive Sleep Apnea.
The tipping point seems to be the unusable stress hormones. They increase inflammation and so increase restriction. So what started as a fight becomes a war. A second tipping point appears to happen as the excursions into the hypocapnic realm become severe – which appears to hyper-stimulate breathing. Those of us who have awakened to breathing hard with our heart beating out of our chest and had a lot of trouble quieting down, certainly with the mask on, have seen the consequences of that war I do believe.
Well I would love to chat but I need to go gear up for another 400 hours this summer. And finally getting in my 10K steps a day, and upper body development and Qigong and …
You did not answer the question -
In terms of Oxygen Levels and Sleep Apnea I believe the most important question simply is "why do those with Sleep Apnea desaturate so quickly". Blood oxygen levels should not go down that fast.

Why????
