Question about hyperventilation

I have question about hyperventilation. This is explanation from kaplan which I don't quite get it

"Bicarbonate ion acts as a buffer to maintain the pH of the blood. For example, metabolic alkalosis will cause hyperventilation, which will effectively increase the concentration of CO2 in the blood, which will then lead to the production of more carbonic acid, decreasing the pH of the blood."


I always thought that hyperventilation causes "decrease" of CO2 in the blood causing elevation of pH..... like if you have too much CO2 in the blood, pH goes down and you breath more and elevate pH to the normal level right?
I am getting confused.... please help!!!

lol.

Hyperventilation = rapid breathing = rapid elimination of CO2 from the blood = less formation of carbonic acid = less H+ in bloodstream = higher pH blood.

You are correct, Kaplan is wrong.

the book probably means hypoventilation.
