why does PCO2 (partial carbon dioxide) decrease during hyperventilation?
                     




Crys
Put simply- Hyper= too much or too fast ventilation= breathing When you breathe too fast you are exhaling more than normal therefore the PCO2 or PaCO2 decreases.


CJ
You are exhaling carbon dioxide very rapidly, causing it to drop. It also cause your body to be in a state called respiratory alkalosis. That's why the solution is breathing through a rebreathing bag.


jml3148
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.

bec of rapid breathing or overbreathing we inhale much CO2 so the body compensates by decreasing PCO2 level in the body..
