24 AHI Pie Charts: Trying to understand where I Am - Spy Car - 09-12-2016
I'm attaching 24 AHI pie charts from SleepyHead data.
I'm new to treatment and am attempting to makes sense of how I'm doing. Night to night comparisons look highly variable to me, but I'm a neophyte.
I really appreciate any input from those with more experience. I can post other data as requested. I'd had a lot of fatigue and am trying to get better.
Thanks,
Bill

Night be night comparisons are not too useful.
The trend I see is that by the numbers you're doing OK.
Your apnea is generally dominated by obstructive apnea.
In time, you may wish to narrow the 4-20 pressure window.

How does one determine how to narrow the window, and in which direction first?

Most important would be the min pressure.
By being so low, the machine has to detect several events in close temporal proximity to raise pressure enough to quash obstructive apnea.
One the positive side: Resmed machines are fast to attack (raise pressure.)
You may get several suggestions on setting min pressure. I like mine to be near the average pressure computed over several weeks of wide open limits. Some may suggest 2 cm-water below the 95th percentile.
So, you may wish to post the statistics page.
Also, a typical daily page showing graphs for events, flow, pressure and leak.

Here is a grab of my Statistics page. If there are days that look "average" to you from my post above, if you can tell me the row and column numbers I'd be happy to post Daily information as well.
I really appreciate the input.

Keeping in mind that your therapy is going rather well; and there's no compelling need to make any adjustment...
Anything you do is sort of fine tuning. Do you feel starved for air when you first start out at 4 cm-water? Many people do.
Take a look at the pressure stats for last week.
I don't know your mathematics background. Let me suggest that you review this short treatise by a fellow hosehead --

Pretty much what justMongo said. Your numbers look good, and I would only add that any changes you make, make them small and slow. Give yourself time to adjust to the changes before making more.

Try posting a single typical night of detail. http://www.apneaboard.com/wiki/index.php?title=SleepyHead_Chart_Organization
An image like this provides a lot more clues to correlate when events are occuring and if there is a pattern related to sleep stage, position or pressure. You are having pretty consistent results, and without seeing these details, I'd say you need a higher minimum APAP pressure.

No, I don't feel starved for air at 4. I prefer the pressure being lower from a comfort standpoint. My hope is to maximize good sleep and reduce fatigue. There is a lack of both. So far the machine (which I'm committed to using and hopefully mastering) has not yet proved to be a magic bullet to dreamland. I am still not refreshed.

Could you pick a night (or as many nights as you want ) from the ones above?
I'm happy to supply the images. I'll put up whatever you wish to see.
I can't choose what is "typical" based on my uninformed knowledge base. And if I can do better asking for help.....
I appreciate your sharing your experience.
