The flashcards below were created by user xangxelax on FreezingBlue Flashcards. What would you like to do?


  1. Why is the alveolar partial pressure of O2 100mmHg and Co2 is 40 mmHg?
  2. Why is 30% of ventilation considered "wasted"?
    • Dead space is taking up space and getting it to the alveoli
    • No gas exchange going on here
  3. What is the relationship between alveolar ventilation and alveolar PCO2?
  4. What is the relationship between alveolar PO2 and PCO2?
    Indirect relationship
  5. What is the alveolar ventilation given the rate of CO2 production, alveolar CO2, and K for the alveolar ventilation equation?
  6. What is the relationship between alveolar ventilation and alveolar PCO2?
  7. What is the relationship between alveolar PO2 and PCO2?
  8. What is the difference in ventilation at the apex and base of the lungs?
    • More compliance at base of lungs b/c not inflated as inflated as the apex
    • So better ventilation at base
