It would be a worthwhile trade off if I was sleeping better IMHO.

The difference in AHI is really insignificant and could just be part of the normal variances that we see.
I can go from AHI 0.5 one night to 3.0 the next night and change nothing. I can go from a week with AHI always been 1 to 2 and then have over 5.0 one night. It just happens. Also everyone needs to remember that AHI now includes central/clear airway events and sometimes CAs are where the most variances occur. Since centrals/CAs can also be flagged while awake sometimes we have awake stuff get flagged. So also glance at the event category distribution of any AHI.
If the AHI is 2.5 and 2.0 of that AHI is CA/centrals then we have only 0.5 that is obstructive in nature and that is what we are using these cpap machines for. We don't treat CAs with pressure from cpap machines. We pretty much have to ignore them unless the numbers are higher than we want to see and happening often. If CAs are a big problem that's were the that high dollar machine comes in.

Support mainly. Especially if the person maybe has really close nostrils and the pillows tend to want to flare out just a little.
O rings are also used for support.

I realize this thread is a few months old, but I'm wondering how you're doing with the Liberty. Do you find the nasal pillows comfortable or do they make your nares uncomfortable?

Since I went to the large pillows, it's been fine.

Only issues I run into are that if I get off schedule with soaking & boiling the silicone, then one pillow starts to slide into the outside of my nares and starts to leak a little.
