Alveolar O2 tension is______________?
Correct answer: A. Increased by hyperventilation
- A. Increased by hyperventilation
- B. Decreased by hyperventilation
- C. Similar to venous O2 tension
- D. Not affected by respiratory depression
Explanation
Hyperventilation removes more CO₂ from the alveoli, and the alveolar gas equation therefore predicts a rise in alveolar PO₂. Respiratory depression has the opposite effect, lowering alveolar oxygen tension.
