C-Flex and EPR User Experiences

I have been using a ResMed AirSense 10 for about three months and have been following my results closely with OSCAR. I've read the forum comments and watched the YouTube channels and have made adjustments carefully to my therapy...with excellent results I might add. I've gone from an initial AHI score or 61 to a regular nightly score of around 1.0. Last night my score was 0.5 So here is my question, why is the conventional wisdom that EPR or C-Flex is something to be weened off of? My score IMPROVED slightly when I added it to my settings and my mask and breathing comfort level went way up. My pressure is 9 and I am only using an EPR setting of 1 although I will be experimenting with a higher EPR settings while watching my nightly result. I understand the potential for degrading the therapeutic effect of CPAP if this feature is used randomly without any form of monitoring, but if the OSCAR data responds positively, why wouldn't you use this comfort feature?
I'd love experienced users to offer their perspective and experiences on the subject. BTW, I do think APAP is problematic and I have also turned off auto ramping. Conventional CPAP is working very well for me and I follow my OSCAR results regularly, why should I aspire to eventually turn off EPR? Thoughts?

The potential for degrading the therapeutic effect when using EPR..exhale pressure relief or any sort of exhale relief by other brands...is a "maybe potential issue" and not an automatic for sure "this is a problem" issue thing.
If someone finds that the treatment is maybe a little less effective during the drop during exhale it is easily remedied by a simple increase in the base line pressure.

If you are more comfortable sleep better using EPR...I would also be wondering why anyone would set a goal of "getting happy with no EPR".
Or maybe they just like to experiment...that would be a good reason I suppose.
I use a machine that offers what would essentially be EPR at 4 and that's what I prefer.
It mimics my own natural breathing pattern and is extremely comfortable and when I am comfortable I fall asleep faster, easier and stay asleep longer.
Sleep has always been my primary goal....without sleep it doesn't matter much what your settings are or what the AHI is....if you aren't sleeping it doesn't matter.

EPR is for comfort..If I am more comfortable using EPR 2 and averaging 1.5-2.0, there is no way I would turn it off to lower my EPR...It's insignificant.
Changing settings every night is doing you no good.

This is a perfect example of listening to the wrong "conventional wisdom".
These same ignormauses will tell you "you may need a bilevel (only they'll call it a "bipap", which is wrong) without even a glimmer of understanding that (almost) the whole
point of bilevel machines is that they provide
MORE pressure differential than is even possible with EPR, (which can give you more than *flex).

Based on what you've said, I don't think you do.

For the same reason you should turn off APAP.... 'conventional "wisdom"'.

EPR is certainly a comfort feature, but it also helps with flow limitations and sometimes hypopneas. The negative talk about it comes mostly from the fact that some people see an uptick in central apneas when they increase EPR. For small increases, that’s a non-issue, and for larger ones, the simple solution is to back the EPR down. But bear in mind that many people see no increase in CAs when they increase EPR.

2 seems to be my sweet spot.
It's been that way since 2010.
Why wean off something that works this well?

It'd be fair to say that
most people don't see any increase.

Very true, and don't need to go to bipap unless you're suspecting mixed or central apnea. Once I keep my nasal and throat clear (Afrin and Guaifenesin) cpap with rather mild to moderate setting is all I need. However, when it gets brutal, bipap was a life saver, literally.

BZZZRT. wrong.
Mention ignoramuses, and one pops up.

Wrong. I was prescribed a bilevel because of pressure needs. Bilevels go to 25 cpaps only go to 20.

Thanks for everyone's contributions. I have increased my EPR to 3 and bumped my pressure slightly to 9.6. This was last night's OSCAR result. I won't be changing anything!
For some reason I am not able to add my attachment, but it was of a great night's sleep with only three events over 7.5 hours.

Somebody needs to google "ween".
Not to be confused with "wean", which actually corresponds to the OP's intent.
Ween is a rock group, and was used in olden times to indicate belief.
The vocabulary frog has spoken.
