RE: Dreamstation 2 vs. Aircurve 10 (Dry, Puffy Eyes)
Back in the middle of September when I was trying a static pressure of 10.0, I was still seeing OA's present with the Dreamstation. Attached is the visual for that day as well as the following day when I tried a fixed pressure of 12.0.
Dreamstation 2 fixed pressure of 10.0.

I am still learning as I am about 7 months into therapy. So since having low AHI numbers I have been hesitant to lower, but the eyes are an issue.
RE: Dreamstation 2 vs. Aircurve 10 (Dry, Puffy Eyes)
Unlike the Dreamstation, your new Aircurve 10 Vauto is much more proactive in preventing obstructive apnea by detecting the flow limitation that normally predicts it. The settings I suggested will allow EPAP to move up to 11 cm, and if it makes you more comfortable, you can raise the maximum pressure to 16 so you get up to 12 cm. I don't think you're going to need it because the pressure support has changed the profile of your respiration from being clearly flow-limited with a tidal volume in the mid-400 mL range to a more normal breath with a tidal volume in the mid-500 mL range. Similarly, your minute vent is 2 L/min higher than with the Dreamstation. If I saw any risk of aggravating OA, I would have reconsidered. Be assured, this will work, we just need to prove it.

This was a night before I got the BiPAP and had the Dreamstation 2 set at 15.0 w/ C-Flex on 3, but as you can see with the Dreamstation is really only got EPAP down to 13.0 and I had a few events. (For reference, thanks @Sleeprider)

You are like a Jedi Knight on this board, extremely impressed and thank you for your insight in this. I will try your suggestion tonight and report back with the results.
Thanks again for your help, greatly appreciated!

Updated settings last night and below is my OSCAR data. Curious if you see anything that i may want to update/change, otherwise should I stay with these settings? I think the pressure in my eyes is a little less today.
16.0/9.0 PS4.0

RE: Dreamstation 2 vs. Aircurve 10 (Dry, Puffy Eyes)
Still zero events, and your machine is not detecting any need for higher pressure. Do you want to try EPAP min 8.0?
RE: Dreamstation 2 vs. Aircurve 10 (Dry, Puffy Eyes)
Possibly, I did notice more flow limits than before, but that's not something I completely have an understanding on when it becomes an issue. I am getting over a bit of a cough and last night had to get up around midnight to take some cough medicine. I am pretty amazed at your knowledge around everything reading this board. Thank you for your guidance and help!

So, I have an update and a question about the humidity settings on the ResMed machines. It seems to be well controlled on the lower pressure settings @SleepRider suggested.
I have been using the 'Auto' for humidity settings on my ResMed Aircurve, but I still have dry, puffy eyes. I am wondering if maybe more humidity could help. I tried once to do it manually and woke up to rainout, which was not a good experience. I know a lot depends on room temp and the climate you live in, but I am looking for a guesstimate of what I could try here. I'm in the Northeast US, in the 40s F at night now, and our room temp is cool, about 66F. Thanks for any support again.
RE: Dreamstation 2 vs. Aircurve 10 (Dry, Puffy Eyes)
My humidifier settings are manual, setting 4, temperature 80 (27*C). The biggest culprit in dry-eyes is a stray leak or mask vent that gets to the eyes. Air entering the nasolacrimal duct in the sinus is not unheard of and can bring air through the tear duct. Humidity is not going to help with dry-eye. Possibly consider Refresh Optive Gel Eye Drops (Amazon). Other solutions might be a blindfold or compress to deflect any air, maintain temperature and humidity near the eyes. I have the same problem from time to time and will press bed covers over my eyes until relieved. Don't overlook the benefits of Flonase (fluticasone propioinate) in relieving congestion that might be a source for flow limits.

When do flow limits become a concern? Numbers-wise?
