I've read the long thread about the dangers of DIY adjusting pressures, so i'd like to better understand the data for myself.
- and also, do i do the adjustments incrementally over a period of time (if so - how long) time, or just reset them in one go?
Thanks for your input,

Not telling you to change anything, just things to look at
1) your min pressure is 5 and your Med Pressure is almost 9, your having large pressure changes
2) large pressure changes can cause CAs, but so can high pressure...just depends on the person
3) EPR will 1 from 3, where yours is set may lower CAs
Thanks, JSL, I agree.
Just to clarify my rational:
min = 9 (from my past experience, your min of 5 is just too low, it won't prevent OSA, 9 is your median)
max = 14 (adds some headroom to your max from the graph and is generally safe)
epr = 1 (larger values may cause CAs, probably not critical in your case)
These settings are generally safe and I would do it in one shot.
Also these settings are close to what works for me.
Just a suggestion.

How about a little more detail on what your saying about
CO2 washout. CO2 is the primary respiratory drive during sleep.?
please explain

Most troubling are the clusters of central Apnea (CA.)
I see you have your EPR set to 3. You might have fewer CAs if you reduce EPR. EPR at 3 will reduce expiratory pressure by 3 cm-water.
That can cause CO2 washout. CO2 is the primary respiratory drive during sleep.

RE: Help with making sense of the data
co2 is the primary respiratory drive, awake or asleep. well, actually it's more your blood ph, but co2 makes it more acidic, you breath harder, co2 blows off, you breath less hard.
the main thing that happens when you take a bunch of deep breaths then hold your breath isn't a big change in oxygenation, it's a large reduction in co2, and when the co2 builds back up, you get that near uncontrollable desire to gasp for more air.
RE: Help with making sense of the data
Yes thank you to all of you for your input, I just need to get my head around all the new info, there is a fair bit lot to take in, especially when brain function struggles at times. I'll post some more data when I am able.
Thanks, mikenz

Thanks for your input - that is really helpful. I was confused about the graph pie chard with "CA" - "Clear Airways", is this the same as "Central Apneas"?

yes
There is a subtle distinction in meaning... Central Apnea implies that the machine (or somebody) has determined that the central nervous system didn't trigger the breath. Our machines can't do that. Clear Airway says only that there was no obstruction and no breath, our machines can determine that. One identifies a cause, the other names the symptom.
It is sort of pedantic...

It is sort of pedantic... to be even more pedantic... "clear airway" is a respironics made up term... if you google it, and -respironics, you get a handful of hits, mainly people on forums asking if clear airway is the same as centrals.
resmed, and, I believe, everybody else, including the medical community, uses "central"

Yes, Clear Airways or Central Apneas = same thing.
