New to CPAP Treatment - a bit lost

How are you feeling? The numbers have been cut in half, so that looks good. Whether it is effective is different to different people. Medical consider <5 effective. I like mine <2 and it usually runs <1. I do think you can get your OA clusters decreased a little more. If you look at your median pressure it runs over 14 so if you get the minimum closer to that number it may prevent those clusters.
There are 2 ways to go at the clusters. One is by decreasing the EPR or turning it off. This takes away the time you are at a lower pressure where Obstructives may start. But you are at a high enough pressure that EPR may be needed for comfort. I know from my experience I need that decrease in pressure for comfort but everyone is different.
If you choose to leave EPR as is, the second way to tackle those clusters is to raise the minimum closer to 14. I would increase by 1cm to 13.4 and evaluate a week. You are getting very close to a great looking AHI. Hope you are sleeping as well as it looks.

Weej, the first thing that stands out to me from your graphs is a nearly perfect correlation of OA to the times when your machine lowers pressure. The solution to these obstructive events is either to decrease EPR by 1 (EPR set to 2.0) or increase your minimum pressure by 1.0 to 13.4. If you really zoom in on the flow waveform for the OA events, it would be interesting to know if the event starts at the end of an exhale (as the line ascends to zero), or if it occurs as you hold your breath (line descends to zero). I would bet the former.

In bilevel therapy, EPAP pressure is titrated up to stop obstructive apnea and pressure support is added for hypopnea and RERA. In the case of the S9 Autoset, things are working from the minimum CPAP pressure line, where EPR drops the pressure 1-3 cm below the minimum set pressure. I think that is where your OA are starting.

Your AHI is not bad, but it shows a consistent pattern. If you want to deal with it, minimum EPAP pressure is probably your key. For you, that is minimum CPAP pressure minus EPR. (12.4 - 3.0 = 9.4 EPAP min)

Here's my data from last night.. Is this considered as effective treatment?

it is considered effective, and it's pretty good. it could be a little better. raising the minimum pressure a little could help.
