Why does PCO2 (partial carbon dioxide) decrease during hyperventilation?!
Question:
Why does PCO2 (partial carbon dioxide) decrease during hyperventilation?
Answers:
The partial pressure of CO2 decreases during hyperventilation because you are exhaling all of it. That's why - to treat hyperventilation - we make someone breathe into a paper bag. This causes them to rebreathe the CO2 so levels go back up.
