CO2 rebreathing

I'm not feeling anywhere near how I felt the night of the sleep study.

While many people have had problems, I sleep and felt great afterward.

I can't seem to feel that way at home.

I feel tried, and heavy limbed -- aside from not having to use the bathroom, I still feel this way after being on bipap for 4 weeks.

Is it possible that I have a CO2 rebreathing problem? I've read the type device I have, Respironics BiPAP, may promote or have a C02 rebreathing problem. I also think the design of the mask I was given, FlexiFit HC407 Nasal Mask, may contribute to the problem. My nose is almost flush with the bottom of the mask and the exhaust port is positioned in the middle.

I also think I'm a shallow breather.....

Any thoughts??

Naaaaaa, CO2 buildup shouldn't happen. What is your pressure ?
Shallow breathing. We breathe about .5 litres per breath. Thats about 1 1/2 soda cans worth. Many masks leak nearly .5 litre per second. Don't worry. Get some rest. The air contains 21% Oxygen. Exhaled air contains 16% Oxygen. You would have to breath it several times to have any effect. Bla, Bla, Bla. Don't let this psych you out else you'll get warts on your face.

Cheers,

Chris

Warts? only if you use the Activa! I've heard that rumor is true

Try a ResMed mask, nasal or full face.
It should help with CO2 rebreathing if it's due to the mask.

Alternatively, you may have apnea or induced apnea which can be looked into, or simply just because your BiPAP settings need to be improved.
For settings, the right setting will rid of shallow breathing.

How would the right setting get rid of shallow breathing?
