The Ventilatory Response to CO₂ is Enhanced By

Question

The ventilatory response to CO2is enhanced by:
A)Hypoxia.
B)Alkalosis.
C)Sleep.
D)Barbiturates.

Accepted Answer

The ventilatory response to CO₂ (carbon dioxide) is enhanced by hypoxia, meaning a low oxygen level in the blood. This is because low oxygen levels act as a stimulus to increase ventilation in order to bring in more oxygen and remove carbon dioxide. Alkalosis (choice B) would actually decrease the ventilatory response to carbon dioxide. Sleep (choice C) may affect ventilation, but not specifically in response to carbon dioxide. Barbiturates (choice D) can suppress the ventilatory response to carbon dioxide.
