I was desperate to get my (regular) Quattro to work when I had a bad upper respiratory infection. After watching the fitting video for the new FX it suddenly became clear to me how the air cushion in the Quattro is supposed to work. So I incorporated that "swing" move they recommend for the FX in the regular Quattro fitting--with the machine on. Viola! The cushion filled with air and hugged my nose, but there was NO pressure on the bridge of my nose. The forehead pad is so loose it's not needed, except to hold the straps on.Is it just me, or does the mask seem to stick out more from the demo guy's face?
I think they finally figured it out with the new Quattro FX. And that "sticking out" angle is the key. Too bad I'll have to wait forever and a day for it to get on the Kaiser formulary so I can try it.
