I woke up several more times that the number of sessions shows. Those are only the times that the face farts were so loud they were causing the audience (aka my wife) to heckle me. The two longer breaks are a trip to the washroom and an early morning face wash when the skin oils would not allow any seal at all. Yes, waking up this often is why I feel so horrible. But what do about it?
I have an appointment next Tuesday with a new sleep doc. I am hoping he does not just say "Your AHI is low, give it more time". I have had a professional SPO2 monitor on all night and I was told the readings were fine. I also have one of the CMS ones and the last time I used it, my median as 97 and lowest drop (briefly) was 91. But that was not with a Tidal Volume like this. I will try and remember to were it tonight.
Some related graphs from that night:
I never considered the inhalation / expiration ratio. I might breathe funny. I feel that I tend to be a shallow breather. Some detail graphs:
Quote:At times when I see my inhalation/expiration ratio go above one, if I look at my breathing flow rate waveform graph, I will see that the "pause" at the end of exhalation seems to have edged slightly above zero on the graph. I'm not sure how that can happen, but it apparently has the effect of causing the pause at the end of exhalation to be counted as part of the next inhalation.
If I am understanding that correctly, my graphs show the same pattern.
And now, filed under "What a difference a night makes", is last night's graphs:
Snoring all but gone, but replaced my hypopneas. Interestingly, almost identical time in apnea. And the pressure is not maxing out. I feel a bit better today, but still sleepy and not overly mentally alert. One other change, I changed my fine filter before bed, it was noticeably dirty.
Thanks to everyone for their insights and ideas.
