How does hyperventilation affect the oxygen tension in the alveoli?

Show Answers

It causes an increase in alveolar oxygen tensionIt results in a reduction of alveolar oxygen tensionIt remains comparable to the oxygen tension in venous bloodIt is unaffected by a decrease in respiratory drive

Explanation

Hyperventilation leads to an increased removal of carbon dioxide from the lungs, which raises the oxygen tension in the alveoli. Therefore, alveolar oxygen tension is elevated during hyperventilation. Conversely, it is not similar to venous oxygen tension, and respiratory depression typically decreases alveolar oxygen levels.
