Carbon Dioxide in full face mask????????
HI everyone. ANd thanks for all of your help so far. I had posted a problem about waking up too tired after using my nasal pillows with chin strap. after reading the replies, I AM lip breathing the air is leaking our of my lips when I sleep. SO, that being said the reason that the Doc got me nasal pillows is because he thought since I am a mouth breather, the full face mask (which fits great by the way). ANyway shice I am a mouth breather the docs said that I am getting too much c02 staying in the mask and that's why I am waking up tired. DOes anyone have any input on this? I am waithin for a call back from tha maker of the mask it's a Resmed Ultra Mirage. Maybe I'll just drill a hole in the side of it so the co2 gets out!!! hahah

The CO2 isn't leaking in from the outside of your mask.  It is coming from your lungs.   FF masks aren't as efficient in removing respired CO2 as nasal masks.   Remember biology from high school...  ... animals (including humans) breath in oxygen (O2) and the waste gas is carbon dioxide (CO2).  Plants are just the opposite...  the require the CO2 and their waste gas is oxygen.

Yeah no kidding.... Maybe you mis understood my question. I am looking for suggestions that would correct this problem of the co2 coming from my lungs. Got it?

Sorry, my mistake...  I got it.    I goofed.

I use the Fisher and Paykel FlexiFit HC431 Full Face mask and I don't have that problem (as far as I know).  

How long have you been on CPAP?  How long with the FF mask?  You may be just catching up on your sleep deficit...  you may want to give it another couple of weeks.

Sorry, I edited this post because I can't figure out how to quote someone on this thing!  I try to quote and it includes my post in it!  Good Grief!  Anyway, here's my reply.

Hello there!  From the information that I am aware of, the full face masks are all equiped with an exhalation valve that allows for the escape of the CO2.  On your mask, this vent is located by the bridge of the nose (the little rubber piece with 4 or 5 holes in it).  There should always be air coming out of this vent and you should never block it.  The air flowing through the mask should be able to flush this gas out rather quickly, without allowing a substantial amount to build up in your mask.  Hopes this helps!
