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


  1. 2 oxygen failure
    • hypoxemia
    • -low 02 levels in arterial blood

    • hypoxia
    • - tissue
  2. normal shunt
    less than 10%
  3. blood in excess of 02
    intrapulmonary shunting
  4. amt of ventilation in relation to the amount of pulmonary blood flow
    v/q mismatch
  5. decrease in diffusion of 02 & c02 across the alveolar-capilarry membrane due to
    change in pressure gradiants
  6. 3 hypoxic hypoxia
    • increase altitude
    • decrease barometric pressure
    • decrease inspired 02 tension
  7. seen by a decrease in alveolar ventilation
    hypoventilation
  8. VA formula
    vt - vd

    inadequate blood flow
  9. amount of vt that is used in gas exchange
    alveolar vol = Va
  10. poiseullle's law
    pressure x16 to maintain flow if airway reduced by half
