have a Fisher & Paykel Brevida Nasal Pillow Mask?
I'm just about at my wit's end with this thing.
No matter what I do I can only get a decent nasal seal about 1 night in 10. The tracking metrics on my machine give me "ADJUST MASK SEAL, LEAKING TOO MUCH!!!!" just about every damned night.
Only, it seems as if this mask is intentionally designed not to allow a seal for more than 2.5 seconds at a stretch.
My biggest gripes about it so far is:
It sucks for side sleeping. If you try to move on your side the mask slips and the seal is lost.
The headgear straps have virtually zero holding power. They're incredibly narrow, and tend to slip no matter where you have them positioned. When the straps slip, the mask slips and the seal is lost.
If you tighten down on the straps to the point where they adequately hold the mask in place, it crushes the mask and the seal is lost.
The hose attaches in such a manner as to constantly torque the mask in such a manner that the seal is lost. If you position the hose so that it is a neutral position and placing no stress on the mask, it invariably moves when you move, torquing the mast and the seal is lost.
Oh, and last, no matter where the mask is positioned on my head, the straps cut ACROSS my *expletive deleted*ing eyes. That's incredibly annoying when trying to read.
I've gone through I don't know how many different videos and the like on proper fitting and I'm at my wit's end. I really want to like this mask simply because the pillows are so incredibly comfortable.
But the fact that I can't get or keep a decent mask seal for more than a few minutes at a time is really forcing me to go back to my old Philips Nuance Gel Pro mask and pillows. I loved that thing, but my CPAP provider stopped carrying it, so I'll have to pay for it out of my own pocket.
