You could safely breathe in through your nose, and out through the tube in
your mouth. I think, however, that this might be too difficult to
coordinate, especially in moments of anxiety :)
 
If carbon dioxide really is a trigger, then a mouth mask with little
one-way valves might be made. When you breathe in, flap A opens and you
breathe from in front of you. When you breathe out, that flap shuts and
valve B to the pipe opens.

Of course, a lot more flexible and easy-to-use than my rough sketch suggests!
