holden,
As Sleeprider points out, your image is too small to be useful. Can you repost it?

Increasing the min pressure often will increase the 95% pressure, particularly if you spend most of the night hovering near the min pressure.
But it sounds like you may have had a larger than expected jump in the 95% pressure level.
Quote:On these nights my RERAs have come in two main clusters which are in the first hour of therapy which is the biggest and the last part of the night in which I've been semi awake. The rest of the night only sees a few RERAs.
Ignore the part of the night when you were semi awake. That's likely sleep-wake-junk (SWJ) breathing: In other words, there can be a lot of
normal variation in the breathing when you are semi-awake that the machine mis-scores as sleep apnea related "events". And the machine can and will respond to all that SWJ with pressure increases. The more SWJ "events" there are in a night, the higher the 95% pressure level is likely to be.
Quote:I don't feel quite as good in the morning. AHIs have been under 5 but up in the twos and threes compared to much lower.
I know what you mean here. I've been fighting this a lot myself this fall. Sometimes there's an explanation. Sometimes there's not much of an explanation beyond
bad sleep. What I mean by that is all kind of things can temporarily increase the severity of our OSA, but as those things resolve, our treated AHI tends to go back down to where it usually is.
For me, stress is a biggy: When I'm under a lot of stress, I don't sleep well in the first place, as in I have much more trouble getting to sleep and staying asleep. And when I have this kind of trouble, my AHI tends to go up, sometimes drastically, because a lot of my events are sleep transitional. And there's not much I can do about it except to work on the stress that leads to the insomnia.
Other potential causes of a temporary increase in the AHI include nasal allergy season. Head colds and other upper respiratory illnesses can also lead to increased AHIs that resolve over time.
Quote:The temptation is to dial back my minimum pressure and raise the Aflex one notch.
I'd encourage you to go back to your previous settings if your overall sleep felt even slightly better or at least no worse with them.
Quote:Here is last night. You can see where I woke up. I didn't get much sleep after that.
Nope. Can't see a thing. So we can't tell when you woke up. And that means we can't accurately assess the events.
