too much air ???

my wife bought me a new mask , it worked great for about two weeks now when i wear it my c-pap seems to be putting out way too much air and i can't breath or catch my breath

Sounds more like a machine problem than a mask one, but without having any idea of what machine you have - full name and model #, pressure settings and which mask you have, it's kind of hard to advise.

First question did you change your machine to your new mask (ex full face to nose pillows ect.) if you changed the type of mask.
