Hello @cece55

I'm pretty new at this too... about a month+ in. I started out with a full face mask (pillows under nose but also covered my mouth). That worked 'pretty well' but I decided to switch to the pillow style where the mouth isn't covered. I too experience what you are talking about when you open your mouth the air rushes out... very strange sensation... basically your mouth has become part of the whole pressurized system... so opening your mouth becomes a 'leak'.

I like the nasal pillows much more than the full face. Do you use the type that has the tubes that insert into your nose a bit? I haven't tried those - but I'm thinking about it. I really like the Respironics brand of masks because they allow you to switch out the mask type while keeping all the same head gear (almost all the same)... maybe other brands do that too, but it seems great for new users because you can easily try the other types of masks and find what works best for you. Also... the swivel on the top of the head works great - I have no troubles with the hose at all.

I'm a little confused about the nasal pillows pulling out when you stand up... I always take the mask off while I'm still in the bed. Not sure why you would standup while still connected? As long as the pillow isn't pulled off while your in bed I wouldn't worry about it. I do find that during the night I sometimes adjust the straps... usually just by pulling is down in the back which tightens things back up... I don't adjust the velcro - just pull the strap back down into position. I did find that my hair was making me crazy with all the straps etc. Finally decided to just pull into a short little pony tail - keeps most of it up out of the way and keeping straps tight seems to be working better!!

Hope that helps... JJ
