Sleeping on the Back, Risks of Increasing Pressure

This feeds me with arguments to go up to 12-20 with my doctor. I have no idea why they're so reluctant to go higher. Do they want to keep us from having great sleep? I don't know.

Is there some reason you don't experiment on your own? There's a chance you could take a Sleepyhead report to the doctor and gush about how well you are doing. And, throw away the list of questions.

Yeah, but now that I trust you completely, that reason has gone away. I was just concerned about the health risks of going too high with the pressure, but that has been resolved. Yeah, I will do exactly that, and tell him how well I feel! That's all that's needed here. Questions are best directed at the forum.

That's scary.

I don't even trust ME "completely".

I only meant that with regard to your CPAP knowledge and experience, I worded it too generally.

So I can report that with a setting of min 12 max 20, no C-flex, I really felt how the airways opened up and stayed open. I had some trouble exhaling, but that was to be expected. If I look at the night's chart, I also find that my sleep was smoothest when the pressure was highest (around 16 cmH2O) between 2 AM and 2:30 AM. I woke up after 2 1/2 hours of sleep, probably because of the exhaling stress, and then set it back to min 8 max 14 C-flex 2 just to get through the night. The reason was that the constant pressure kind of hurt my (kind of sensitive) lungs, it was a constant, slight stinging pain. In the later sleeping phase, I again had a lot of waxing and waning episodes, though perhaps not Cheyne-Stokes. So perhaps a ResMed S9 VPAP Auto Bilevel Machine would be the way to go for me, as well.

Too bad that there is no way to detect REM sleep using the CPAP device. Do you think it happens while the breathing is steadiest?

Have a nice Sunday,

Or, just an autoset.

I'd think not, since REM is an active sleep state. (Rapid Eye Movement, and all).

Got it, maybe there isn't any connection whatsoever to the breathing because it just happens in the brain and with the eyes.

What I'm saying is that REM is a more active period of sleep, so calm, slow respiration doesn't really fit with "more active"... see?

Yeah, now I read the Wikipedia article; I think you should see some irregularities in the CPAP graph and if you filmed yourself with an infrared camera, perhaps some rapid body movements. Here's what Wikipedia says:

------------------

Generally speaking, the body suspends homeostasis during paradoxical sleep (= as if you're awake). Heart rate, cardiac pressure, cardiac output, arterial pressure, and breathing rate quickly become irregular when the body moves into REM sleep.[32] In general, respiratory reflexes such as response to hypoxia diminish. Overall, the brain exerts less control over breathing; electrical stimulation of respiration-linked brain areas does not influence the lungs, as it does during non-REM sleep and in waking.[33] The fluctuations of heart rate and arterial pressure tend to coincide with PGO waves and rapid eye movements, twitches, or sudden changes in breathing.[34]

-------------------

We should call ourselves lucky if we get a lot of REM sleep.
