RE: Can CO2 drive Hypopnea?
Your body uses CO2 to drive respiration (not oxygen). Look up the terms "hypercapnea" and "hypocapnea". As CO2 levels rise in the blood stream, inferring poor ventilation, chemical changes occur that increase the respiratory drive. Similarly, if CO2 levels drop, inferring a high rate of ventilation, the respiratory drive decreases. EPR increases respiratory ventilation exchange. As the pressure difference between inhale and exhale increase (also called pressure support), the lungs more efficiently exchange CO2, reducing CO2 in the blood stream. This decreases the respiratory drive in some people, and may result in hypopnea or central apnea as the need to breathe is diminished. By reducing EPR or pressure support, the "flushing" effect of the additional ventilation is reduced, so CO2 remains better balanced. This will reduce H and CA events in sensitive individuals.

RE: Can CO2 drive Hypopnea?
FWIW my 2 cents on "why it is
low levels of CO2 in the blood that suppresses our drive to breathe, not high levels". Our brain is looking for a low level of CO2 to trigger the breathing mechanism to fill the lungs with oxygen laden air and expelling waste air laden with CO2. The low level trigger status is likened to the low fuel light in our cars. The low fuel light is turned on only when fuel level is low enough to illuminate it.
Our CPAP machines blow air in forcing out more CO2 than our brain perceives as normal. Since the low CO2 signal is delayed, we'd get a Central Apnea/CA as a result.

Exercise Training to Treat Sleep Apnea
The following link offers "Throat and Jaw Exercise Training to Treat Sleep Apnea" by the South Dakota State University. I found it very useful.

Arik,
RE: Exercise Training to Treat Sleep Apnea
you said 'useful' rather than something like 'interesting', leading me to think you found the exercises effective?
RE: Exercise Training to Treat Sleep Apnea
I have found the exercises useful and effective.
I have been using them over the past 2.5 years to help manage my OSA.
I started out using the exercises in this video and have added some others, while dropping some of these.
They are part of a more comprehensive approach that I use.
1. Weight management.
2. General cardio exercise.
3. Neck and throat exercise.
For me, currently, it is a much better option than xPAP.

Would you care to share what exercises you dropped and what exercises you added, and why?
I find the sample program schedule a bit confusing. How often do you do your exercises per week, reps/sets etc? Any help would be appreciated!
RE: Exercise Training to Treat Sleep Apnea
Hi ManDown11,
I agree, the schedule that they give is difficult to follow. So I never did. When I first started I did most/all of the exercises from this program twice a day while commuting to work. I would spend about 2 min on each exercise. The ones that I couldn't do while driving I did while out of the car. I spent about 30min, twice a day.
After 3 months I retested using the Resmed Home Sleep Apnea Tester and found that the exercises were doing me a lot of good, getting my untreated AHI into the 5 range.
I am retired now, so I only do my exercises once per day now(no commuting). I spend about 30 min a day while on my treadmill.
I would encourage you to individualize your exercise program. Do the exercises that you believe will do some good and that you will continue to do.
The ones that I dropped are the boring ones that I don't believe help me. (It is possible that they would. I don't know). Most of the ones I dropped are the vocalizing ones.
A couple of exercises that I've added are tongue brushing, rolling my tongue, and and rolling 'rrr's(from Spanish.
Again, I would encourage you to individualize your program using the videos on Youtube as a place to start. There are more videos with other exercises.
Can sudden increase in AHI be linked to Coronavirus infection?
Hi,
After about 6 months of AHI=0.5 on average, it jumped to about 2 for the last 6 nights with no seen reason. Can this jumped be a warning of Coronavirus infection? I'm not experiencing any other symptom.
Thanks,
Arik
Central or Obstructive ?
Hi,
When I hold my breath for a while, what type of Apnea should be reported by the machine? I tried it several times with my S9 and the results were mixed (sometimes Central and sometime Obstructive).
Thanks,
Arik

RE: Central or Obstructive ?
The machine can't detect a "Central Apnea". The event "CA" may be defined as a detected time interval of not breathing and clear airways (detected by FOT). The adjective "central" refers to the cause of the described event which cause is impossible for the machine to determine.
Hence holding your breath causes the event "CA" or "OA" depending on the way you hold your breath.
