Sleepyhead pie charts

Thankfully I had one of the best nights of sleep last night that I've had in a while. Things are getting better, but still have "hiccups". Learned a long time ago with training dogs to never evaluate anything by evaluating short term results. You want to look long term and to look for patterns.

So. Looking at last night, I was trying to see what was different than the two previous nights, which were fair sleeping nights, at best.

Sleepyhead pie charts. It appears that the charts take the top items you are dealing with and develop the pie chart. So if you had 4 different areas that each had an incident of one, and those were your top areas, you'd have a 4 piece pie chart showing each item. Correct? Is it weighted in any way?

AHI. I had almost gotten to the point where I was ignoring this. I've been running under 4 and had two weeks where I was running around 1.5. Didn't seem to make a real difference. Last night it was 0.44 (my lowest reading ever). Last night was one of the best nights of sleep since I started with this in late September.

One last thing. I have the upper limit on my machine set to 11. Last night the pressure never went over 9.8. Some bad nights, I max out at 11. Comments?

The pie chart is nothing but % of each category affecting how big the slice of the pie happens to be. Nothing weighted in it.
I turned mine off as I really don't need to see how big of a slice something might be.
If I had only one event the entire night and it was a hyponea...the entire pie would be hyponea...doesn't really tell me much.

Some nights we have higher pressure needs than other nights. The 2 most common suspects....supine sleeping and REM stage sleep or maybe a little bit of both. Some nights you simply need more pressure.
Back when I was using apap with 10 minimum and 20 maximum I would often have nights where the pressure never went much over 12 and sometimes would never see anything but the little test pressure probes but I might also have a few nights where it might go to 18 (never stayed there long though). In my case REM stage sleep was most likely the primary culprit. My OSA is about 5 times as worse in REM sleep as in non REM sleep.
Since pressure changes never affected my sleep I just left the max wide open and let the machine sort things out....if it had messed with my sleep or caused aerophagia then I would have probably limited the max and made a compromise to maybe allow a few events to slip past the defenses because the side effects of the higher pressure were worse for me than the side effects of a handful of events.

As usual. Thanks again.
