[Treatment] new to this - is it working?

[human]

I just started a week or so ago and I don't notice much of a difference yet.  I'm posting here to start a thread for me and see what y'all think.

Some of this data is coming from time when I was just watching TV and not actually sleeping but that should be fairly minimal.

Things I noticed:
- the pressure starts and stays fairly low
- AHI stays below 4 on all days.

It'll be a lot better to see the daily Oscar data.

I thought I did this before. Still figuring out the forum software

Only change is to raise min to 7. Your EPR is set correctly at full time 3 BUT it can not work with a min of 5.

[SarcasticDave94]

A few things to consider, the sleep test info had a low level of overall apnea, about twice as many Obstructive as Central. Given that there's a mix of Apnea types, you may see some of both CA and OA in OSCAR. They both are controlled as is, but as Stacey said, to gain full EPR 3 benefits, you either have to increase Min pressure or lower EPR to match the Min.

How EPR works is the setting reduces your min by that setting. So EPR 3 reduces by 3 cmH2O, 2 EPR by 2 cmH2O, and 1 by 1 cmH2O. However the CPAP has a physical cap that its lowest pressure is 4.

In other words for EPR 1 to work fully, Min must be 5. EPR 2, min 6, EPR 3 Min 7.

Secondly, for comfort you may want to consider lowering the max of 20 to 15 or so, not less than 12 though as you used max 11.x at least once. Whoever set your machine just handed you near default, adding 1 to Min and someone added EPR 3. Unless you're Mr. or Ms. Default, you're better off with more individual settings.

> Whoever set your machine just handed you near default, adding 1 to Min and someone added EPR 3.

I actually did that (changed the default by 1) -- it started off as pure default. I'm going to experiment a bit with higher presure - but I wasn't sure that was even necessary. It surprised me that the apneas seemed controlled at such low pressure. Is that typical?

I might also experiment with lower EPR to 1 or 2. It doesn't seem that important to me for comfort. I seem to be okay with higher pressure when it does happen.

I increased the minimum last night although the AHI seems worse now?
