I was looking up C02 retention and 02 use at home. Yes, I have been googling again. But on this site I found wonderful, easy to understand explanations. I'm having a specific sleep study being done in Jan. to see if I'm crossing over with dx's. (which I guess is very common with COPD) My terminology may be a bit off. Simply put my specialist wants to measure my breathing, and to see if my CO2 is increasing with sleep, and if during sleep I stop breathing for short periods of time. (apnea)
So question for the group who uses C-pap, is this a form of 02 delivery not using your 02 tanks ? I'm sure they'll explain it at my next appointment with my Dr. for test results. Just like to be a bit prepared. Thanks !
