When I was trialing full face masks, tried F10, F&P Simplus, and Quattro Air
In order of preference:
1- Quattro Air
2- F&P Simplus
Whats the leak rate?
Looks like the elbow is not attaching to the mask properly (since you mentioned that the leak stop if you hold the elbow tight to the mask. Maybe the elbow is defective. You may want to test the fit of the elbow, by using the machine to blow air into the mask while you hold the mask in your hand.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.
I use the F10 and have not had that problem. It does have a circle of air vents (which are essential) where the elbow joins the main part of the mask, but I assume you weren't referring to them.
Of the four (full face) masks I've used, the top three in order of preference are:
2. Quattro FX
3. Quattro Air
The Quattro FX was more consistent than the F10 in terms of low leaks, but I prefer the lightness and slightly better ease of use of the F10. It's also easier to wash as it has only 3 parts.
I got most leaks with the Quattro Air - I think that was because the forehead rest (if that's the right term for it) was being moved by my head on the pillow (I'm a side sleeper).
I found out a new mask must be washed out, really good.
there is manufacturing residue on the silicon which will
sometimes cause leaking. I just rinsed it which did not work well.
The connection on my Airfit F10 seemed a bit loose too. What worked for me was a couple wraps of scotch tape around the the elbow then insert back into the mask... just make sure the connection is still able to swivel.
On the Quattro FX i had issues with the mask riding up my nose during the night causeing air leaks into my eyes. What fixed that was a strap going from both sides of the frame (the plastic directly under the eyes) down around my chin.
I've had my share of trouble with my Airfit leaking as well. My RT suggested that I (1) wear it lower on the bridge of my nose (now I remember him mentioning that on day 1); and (2) tighten the straps that hold the lower portion in place. Since doing both of those, the irritating leaks have been nearly non-existent. Yay!
(This was when I went to the DME to pick up nasal pillows to try instead!)
To all, to each, a fair good-night,
And pleasing dreams, and slumbers light.
