Actually, it might be ok for high pressure for you. They gave me one to use at my vpap titration, and my pressure ended up at 25/16
So I asked the RT to bring me one when she set up my equipment this past Monday. Unfortunately, when she fitted it to me and turned on the machine, (not at full pressure, even), I had a major anxiety/claustrophobia attack and couldn't tolerate it. I was really disappointed, because it had seemed to work well for me. I guess that it just seemed a little "too" real when all that stuff is suddenly sitting on your own nightstand.
I ended up with a F&P Zest nasal mask, but I'm thinking I might want to try another ff mask. Having to keep my mouth closed is giving me some anxiety at this point.
Actually, the whole thing is giving me anxiety at this point. But it will pass.
