This is inconsistent with NLM guidance for hyperventilation (
https://medlineplus.gov/ency/article/003071.htm) which states:
"If you start hyperventilating, the goal is to raise the carbon dioxide
level in your blood... Ways to do this include:
2.To increase your carbon dioxide, you need to take in less oxygen. To
accomplish this, you can breathe through pursed lips (as if you are
blowing out a candle), or you can cover your mouth and one nostril, and
breathe through the other nostril...."
Based on a cursory search of the articles and the NLM web source, the
research seems to be conflicting with respect to pursed lip breathing
effectiveness for ridding the body of CO2.

Does anyone know of or have you seen empirical data re the expulsion of
CO2 in human breathing? I've long heard that one with emphysema should
inhale thru the nose and exhale by mouth with pursed lips. The pursed
lips have been deemed significant to ridding the body of CO2. Can
anyone shed empirical light? Thanks.
