UARS CPAP setting? Help me interpret OSCAR data

[throwaway0815]

I slept a couple nights with the full face mask now and the leak rate went down by a lot. However, I noticed AHI and flow limitations went up.

Any suggestions?

Congratulations on finding a FFM that works for you! If you decide to stick with it, could you change the mask info in your profile?

Although your AHI is higher, that's mostly due to the time period you zoomed in on. The rest of the night looks good as far as events go.

The cluster you zoomed in on, plus the big flare of FLs after it, might reflect a postural problem, most likely tucking your chin down toward your chest. If that happens just occasionally, I wouldn't worry about it, but if it shows up fairly regularly, you will benefit from using a soft cervical collar. More here:

I would recommend sticking with your current settings for maybe another week to get a better sense of where things stand. At that point, you may well want to increase your minimum by 1 and increase the EPR to 3 to see whether that helps with the flow limitations.
