I don't think there is any question I hyperventilate in my sleep probably when I am awake too. I use a Cpap and can rarely get my AHI below 7 or 8 with one exception. (AHI is the amount of apnea and/or reduced breathing events per hour). There is a little device called a TheraVent that allows one to breathe in normally but greatly restricts the exhalation thus greatly slowing the breathing.
When I wear a TheraVent in a full face mask while on Cpap my AHI drops to or below 1.0. I believe this is because the reduced breathing generates a lot of Co2. In turn the Co2 helps generate Nitric Oxide which opens everything up.
I have also made a simple device that mimics Buteyko breathing by using 1 inch 3M waterproof tape and used it. Cut a piece that a little over 2 inches long. Using a leather punch open holes at the nostril locations that are between 2 and 4.5mm. Bigger is more comfortable at first. Wash and dry your nose and tape it on. Your nose breathing is instantly restricted like Buteyko breathing.
By the way, is there a trick to bag breathing or is it just a matter of holding a paper bag over your nose and mouth and breathing?
