PCO2 levels decrease during rapid breathing.
When a person is hyperventilating, the PCO2 decreases. This is because a person is breathing enough to expel the CO2 out of the lungs making it decrease.
Increases due to greater oxygen demands and a rising blood CO2 concentration (PCO2).
PCO2 levels rise during breath holding. The longer the breath is held, the more PCO2 will rise, even to the point of syncope oclcurring (passing out).
Plasma pH will Decrease
PCO2 of the blood. Co2 removal is the biggest reason for breathing.
During hyperventilation, the CO2 level will raise. The reason for this is because when you hyperventilate, your rate of exchange is not enough to remove the CO2 in the lungs.
The body responds first to the partial pressure of carbon dioxide in the blood. PCO2)
No, it is higher or the CO2 would not move out of the lungs.
