RE: Leak vs. venting?
Plus +1 on the Gorilla Tape - it's great stuff. I use it for "almost permanent" repairs, or stuff that I'll need to fix "completely" at a later date.
As far as the Quatto FX mask, I'm using the correct method of fitting (nose bridge and swing down), but find that I need to tighten the straps a bit excessively to eliminate nose bridge leaks toward my eyes. Due to this tightness, the mask will slide up my nose bridge, and this loosens the upper straps a bit. I find that the nose leaks don't recur when this happens, but the lower edge of the mask cushion ends up just under my lower lip, and if my mouth opens during sleep, the lower cushion ends up in my mouth, with resultant leaks there.
I spoke with my DME therapist about this, and she suggested that a larger mask might alleviate this problem. I didn't have use of the ResMed sizing tool before ordering the Med. size, but I found a web reference for sizing DISTANCE between nose bridge and chin "dimple" - 3-5/8-in for Small, 4-in for Med, and 4-3/8-in for Large. I also found another supplier that had a "sizing tool" PDF available, but this ended up being only a pictorial of the ResMed tool, with three different adjustments shown for the three sizes. And measurements of the three "pictures" didn't agree with the distances I quoted on the other site. So, I'm still not sure I have the proper size mask.
Edit - I also found a review thread here about the Quattro FX, and there is more than one reference there about ResMed's sizing tool for this mask not being accurate. Maybe I should ask ResMed directly?
Thanks again for the help,
John
PS - sorry for putting all this scrap about the Quattro FX in this thread, but I'm still pretty new at this therapy and the forum.
