EPR on or off

I'm trying to get a better understanding of EPR. What are the benefits of it being on VS off. Why would a user want it on as opposed to off? thanks for your help.

Comfort--yours.
You get to decide for yourself.

I looked up a recent thread of yours, and earlier this month you had the EPR on at 3. What this means is that your pressure when you exhale is 3 cm H2O lower than your pressure when you inhale. If you lower the EPR to 2, 1, or 0, you'll get less of a pressure drop and therefore have a little more pressure to exhale against.

As chunkyfrog says, this is mostly a comfort feature. For a few people using EPR can reduce flow limitations and RERAS; also for a few people, it can increase central apneas. You should just experiment and see how you like it. Try it out during the day at each of the settings to get a sense of it.

Yes Miss Emerita you are correct about it being turned on and at 3. Someone told me along the line that I should do it so I did. I did not totally understand it or how it affects other things. I did understand it was for comfort. Now that I'm getting things more dialed in I'm trying to understand it all better but I think I'm a slow learner. Lol. Thanks

EPR allows you to exhale against a slightly lower pressure. Some people like it, and others do not. Personally, I like it. I use a bilevel machine which has the capability of putting out more pressure than a regular CPAP machine, and had the capability to have a larger difference between inhale and exhale pressure. When you use EPR, you are essentially using a bilevel machine. You are breathing in at one pressure and exhaling at a lower pressure. If you find it easier to exhale at the lower pressure and it doesn't interfere with your sleep, there is no reason to to use it.

Ditto to all the above replies. It's a personal comfort thang. Over time, I think people eventually turn it off. When you first start using cpap, you are not used to the pressure. After prolong usage, you seem to get used to the pressure, and the slow pressure build up could disturb your attempt to go to sleep. Heck, I often have to check to be sure the machine is on!
