AHI in sleepy head

Post by Woodgod » Sun Dec 23, 2012 9:37 pm

I was reviewing some of my date in sloppy head and noticed that on some nights my AHI can climb as high as 10-12 for a period. But yet my average for the night is still 3.63. Does that mean I am just not getting much air for that amount of time that the AHI is high? Or does it not work like that?
I am still not very clear on how to read some of the sleepy head date. I tried to look at the tutorial but it said it was under construction, am I doing something wrong? I would love to be able to digest some of this data better.
I am considering tracking when I eat my dinner and other events like that. To try and keep a bit of a sleep log, to try and figure out what might cause some of my bad nights and what gives me a good night’s sleep. Have any of you done this and if so

You eat your dinner in your sleep? .........It doesn't work that way. You need to be sleeping to track your AHI.

You probably are looking at the AHI graph which is an hourly AHI and yes, it can be higher for a couple of hours and have nothing go on for some other hours and end up with overall AHI around 3.
The 2 most common causes for little clusters of AHI like you are probably seeing are supine sleeping or REM stage sleep.
Your pressure may not quite be adequate for those times.

Remember that AHI is average value of the events during the time you used the machine. Sleepyhead will also show you the max level in the small table at left.

The general consensus seems to be that it's average AHI, not hourly AHI that most accurately gauges the harmful effects.

Also, look at the events to see how long they are, how completely you stopped breathing, etc. A two minute apnea hurts a lot more than a 20 second hypopnea.

It could be the apneas etc that show up during your REM sleep, these are part of the deeper stages of sleep and are natural if they are not excessive. Or you could be marginally awake and tossing/turning. For some easy calculations click on my member name and search my recent posts for tidal volume. That tutorial will tell you how to throw out your sleep/wake junk and determine what your total hours of real sleep are. Scroll down and click Search User's Posts. The search window is near the top. If you have questions, just ask.

I like my ResMed AirFit F10 FFM - reasonably low leaks for my ASV therapy. I'm currently using a PR S1 AutoSV 960P Advanced. I also keep a ResMed S9 Adapt as backup. I use a heated Hibernite hose. Still rockin' with Win 7 by using GWX to stop Win 10.

I went back to SH--Events--and expanded them. I had no idea you could do that! Noted a (173) Periodic Breathing (I see a few of the wide green markers on my other reports), now need to figure out if that's a good number or bad. AHI only 1.33
Thanks for the tip
