Thank you, so potentially the final AHI number can be inaccurate? If the majority of my events occur in the first half of the night, but they are shared out over all the extra hours when lm not having events, whether awake or asleep, it's probable the total figure of events is watered down in the process? How is this accurate? Maybe in future l will use the machine for less hours. I go to bed early because of fatigue, and mask up about 9pm for sleeping but my sleep is so poor and fragmented l stay in bed longer in the hope of getting a bit more zzzzzzz. So most of my usage numbers are around 9 hours. My actual sleep time is more like 6 hours.

It is a calculation of "Events per Hour", add uneventful hours, it will dilute your AHI to a lesser value.
Like mile per gallon, sometimes the road runs downhill with a tailwind and my instant MPG readout looks real good.
But then when I head home it is uphill against a headwind, not so good for the instant MPG readout.
Then you look at the average trip MPG and it not as good nor as bad as the instant readout felt.

I hope this helps.

Please install OSCAR and post some reports we have some very talented individuals here on the forum that could give more detailed help with some OSCAR Reports posted.

If you use OSCAR to review your data, you can select a portion of the night to exclude time where you know you were not sleeping to have it recalculate AHI for the selected time.

Thanks for pointing that out. That's pretty neat. How does one set that up?

Also, I wonder if it would be useful to have it automatically chop off the first and last ~30 minutes of the night since I'm usually tossing and turning and settling into the night. Im sure those times are not super useful in the overall calculations.

You just select the range (like selecting a range of text in a document) using your mouse to zoom in. Please read the links in my signature to further learn about OSCAR. Please publish the code as to how you plan to automate the pruning of the beginning and ending times of a sleep session.

Put the card in the computer and see what was happening.  If they are clustered it is likely that they are positional i.e. based on something happening at the moment rather than through out the night.  I don't worry if they are clustered because I know, or believe, that the mask is being stressed because of my position.

Looking at the chart you posted from your sleep study, you should almost certainly be covered by most insurance, including Medicare, for an ASV.

Thank you to everyone who has replied to me. I will try to get Oscar today. I have done 100% compliance, had no mask leaks and had pressure raised to 15 but no improvement in symptoms, in fact fatigue and fragmented sleep is worse, and lm stuck in the 10 to 13 AHI range, 50/50 obstructive and Central and still Cheynes Stokes. I have been referred to specialist doctors as having "severe complex sleep disordered breathing " . Meanwhile The sleep clinic nurse is annoyed with me for asking too many questions and being concerned about the detailed data. I'm apparently not supposed to be taking an intelligent interest in helping myself get better.

Thank you for that!
