Vitera humidification issue (?)
Vitera humidification issue (?)
(Searched to see if this already addressed-- just point to a thread if I missed it)

Howdy.   Just switched from a Resmed Airfit 20 to a F&P Vitera, primarily because of what I'd read about the looser fit of the Vitera. With my relatively high pressure the Airfit would squeal or 'trumpet' too frequently unless the straps were annoyingly tight (often headache-inducing annoying). 

Love the fit of the Vitera, but now I wake at least 2 or 3 times a night owing to my entire oral cavity having become ridiculously dry/parched. Still using the DreamStation, with self contained humidifier.  For the 1st few days of Vitera use I had humidity set at 3, as had been the setting when using the Airfit; then bumped it to 5, with no improvement.

The venting of the Vitera, that instructions warn not to impede, makes for a more significant and constant air flow than the AirFit.  I'm wondering if the seemingly faster, constant air current through the mask reduces the effrective humidity.

Just to pre-emptively remove a causal variable-- once asleep I do have a tendency for open-mouth breathing at least part of the night, but that's not new, and only occasionally did I experience a bit of 'dry-mouth' in the 2+ years I was using the AirFit.

Anyone else have a similar issue? Any thoughts regarding tweaking the venting?

Thanks for any help--  Jim
