This may be a silly question, but...

I have been trying to use both a nasal mask and a full face mask (not silmutaneously). I like the nasal mask's "comfort" more but I can breath easier when I can use my mouth to help out my nose.

My question is: Should I be using different pressure settings depending on whether I use a full face or a nasal mask? It seems like the nasal mask would have more resistance (and maybe need higher pressure?) than a full-face mask where you can breathe through your mouth.

Of course, I don't know if this is true, which is why I'm asking if I should be changing pressure settings depending on the mask style.

If the sinus passages allow normal airflow, there is little difference at the points of obstruction between a full face mask and nasal mask. Any sinus blockage can significantly reduce the cpap pressure in the airway below that point. Most sleep labs titrate using a nasal mask so the cpap level determined includes whatever pressure loss may be derived from the sinus.

Based on your comments, you have a good understanding of the situation.

I know my cpap machine has to be set to which mask I use...at least that is what the company did everytime I changed my mask before finding the one I kept....but I'm no expert neither....

Some (maybe all?) ResMed machines have a "mask setting" to enter what type of mask you're using. Puritan Bennett and Respironics machines don't have you do that.

And now I know...

I do have a narrow nasal passage, plus I have a deviated septum and a spur according to my ENT. That may be why I seem to need more pressure to open my throat. The funny thing is I start the night breathing fine and then my nasal passages seem to swell. The doc today gave me a Rx for Rhinocort (budesonide) which I will try.

I guess I'll try to crank the machine up a bit when using my nose mask vs my full face mask.

Thanks for your help.
