Hypoxia and hypercapnia · Physiology

Which change occurs in hypercapnia-induced ventilation?

  1. Decreased tidal volume
  2. Decreased respiratory rate
  3. Increased alveolar ventilation
  4. Reduced chemoreceptor sensitivity
Show answer and explanation

Correct answer: Increased alveolar ventilation

Hypercapnia stimulates ventilation through central chemoreceptors. This increases alveolar ventilation to remove CO2.
