Early Morning change in AHI

[me50]

Good morning.

I personally am not bothered by the larger font size. I would rather deal with that than something really inappropriate like asking about different drugs that are not for OSA treatment as has happened before or fighting or slamming other forum members, etc., and it was easier to read than the smaller print.

More importantly, I think that we should focus on helping the OP and not focus on the font size, IMHO. If there is a violation or a concern from a poster, I am sure those that moderate the forum will discreetly discuss it with the poster.

That being said, I will think about the question and see if I can think of anything to suggest other than what has already been suggested.

Have a great weekend all.

Good point.

Not about violation or a concern, I tend not to read them and cannot be helpful if don,t read them

... but does not seem to be such a concern for others who has been helpful in answering OP concern

I generally assess my own AHI when necessary since the machine doesn't know when I was awake. It's pretty easy to do if you know how long you actually slept. That's the challenge but it's not much of a challenge to just dump the first and last hour's events. That will give you results close enough for government work. The rest is simple math to get events/(hours - 2). I mostly do that when I can see that the machine's processor has it all wrong.

BTW, I have very poor sleep efficiency and usually take 45 minutes to an hour to fall asleep. During that time I often get several centrals and even an obstructive occasionally. Some of them are caused by me swallowing, clearing my throat and just general grunting, etc. YMMV in that respect so deduct as fits your sleep efficiency.

A secondary benefit of that method is I never look at the readout during the night since I don't respect it until I see the graph.

I may be slow today but I'm not exactly sure what you were trying to say

[Paralel]

I enjoy how people say to focus on helping the OP, but continue to discuss the one sentence another user wrote instead, even though it is completely irrelevant to helping the OP. Pot, meet kettle.

[retired_guy]

Well shoot Paralel, we gotta have something to talk about!

[Mouchet]

I have the exact same problem.

Any solutions?

1100 -1 about 2 ahi

3-5 about 5 ahi

6-730 about 8-12 Ahi

Resurrecting this thread to say that I have the same problem.

00:00 - 04:00 AHI .47
04:00 - 08:00 AHI 5.07

Makes me wonder if I should just go to bed at 8 pm and wake up at 4 am

Two things probably contribute:

1. Sleep stage
2. Sleep position

In the first four hours of the night, it is expected to have two REM segments approximately 20 minutes each. After the first two sleep cycles where we have N3 deep sleep, the rest of the night is spent bouncing back and forth between N2 light sleep and REM stage in a less predictable pattern. REM is when the body's musculature is most relaxed and most likely to experience upper airway collapse, so many people experience more events during REM and therefore AHI will climb throughout the rest of the night.

Another thing is sleep position. For various reasons, it is common to have more events sleeping on one's back. I for one know that I sleep better on my side, but when using CPAP, especially FFM, would roll to my back at some point in the night and experience more events. Many members here have had success using a soft cervical collar to support the chin and align the neck to take some away some of the issues associated with back sleeping.
