I did hospital lab study and it came back with AHI 31. I then did a separate at-home study (set up by a technician) that came back with AHI 10.1 (and also showed my blood oxygen fell to 86%). Both of them flagged hypopneas as the cause.
For some reason my original healthcare provider encouraged me to set a very high pressure (
min 14, max 20) and it was causing me a lot of discomfort. I then sought a second opinion with a different provider who thought these settings were crazy and recommended
min 4, max 15 and I'm now feeling better most days.
But many days I still feel awful and can barely function.

Now, THOSE settings are crazy.
Why is that?
Because a setting of 4 is correct for very very *very* few people. many people have trouble even breathing at a pressure of 4.
Reducing the max pressure is also foolish except in a few cases.
Based on the screenshots you provided, your pressure should probably be 9-20 Or 12-20 if you're going to use EPR.

I've been testing EPR 3 (min pressure 8, max 15) the last three days and I feel a lot worse when I wake up. I'll give it another day until I change it just in case it's a fluke.
Can anyone help me to understand, looking at my charts above, the appropriate pressure settings with EPR 3 turned on? It feels very light - like I'm not wearing a CPAP at all. I suspect min pressure should be higher.
Palerider suggested a mimimum pressure.
So did your doctor:

I forgot to mention that during my first sleep lab they did split study on me. The same doctor first put me on min 9 max 20. Then a few days later she checked the data and bumped me up to min 12 max 20. Then min 13 and finally min 14
I know its difficult to keep track of things when were' sleep deprived.
For the coming week:
Stick to min 7 max 15 no EPR.
Keep a daily diary of how you felt when you got up.
Then post the charts, and for each one, separately, tell us how you felt.
EPR lowers the effective minimal pressure, which is why PR said "if you're using EPR = 3, and you need a minimal pressure of 9, then tell the machine to give you a miminum of what you need + the EPR its' subtracting from the exhale pressure. EPR is there to make exhaling agains the minimal pressure feel easier.
You didn't say what made 14 feel so bad - but maybe you do need it to get rid of those flow limitations.
Your flow limitation may be impacting your oxygenation - and a
gradual raise in pressure may be necessary.
And now here is my secret, a very simple secret; it is only with the heart that one can see rightly, what is essential is invisible to the eye.
