Default UWorld q 528 (respiratory physio, help!)

Incredibly confused by this question. Basically, the answer requires you to know that HYPOCAPNIA = ALVEOLAR HYPERVENTILATION

What does alveolar ventilation have to do with PaCO2 levels??

PaCO2 level is influenced by:
CO2 production
CO2 expiration

- the first thing is constant (if the patient doesn't start exercising or whatever)
- the second one, therefore is the one that changes
He obviously has hypocapnia. You reach hypocapnia by HYPERventilation - you need to breathe faster if you want to expire more CO2.
