Hyperventilation causes decrease in PaCO2 and and increase in pH.
Is this correct and why.

I think you are correct. Hyperventilation means that not only are you breathing in a lot more oxygen, but you are also breathing OUT a lot more CO2. Therefore PaCO2 should drop. Someone correct me if I'm wrong.

u're right about a lot more CO2 being blown out during hyperventilation and therefore there is a drop in PCO2 and also a rise in PO2. as there is a lot more carbon dioxide being blown off, there is also a rise in the pH. although i'm not very clear on how the alkalosis is produced.....can someone help me there.

Because a drop in PCO2 causes H+ to drop. That causes alkalosis. See KAPLN NOTES ACID BASE BALANCE chapter. The _HCO3 also drops but only slightly as the kidneys compensate.
