Under which of the following conditions can the alveolar partial pressure of carbon dioxide (PACO2) be increased?
 
  1. When the body increases its production of CO2 (VCO2)
  2. When the dead space ventilation per minute is increased (VD)
  3. When the minute ventilation is inadequate (VE)
  4. When the alveolar ventilation is decreased (VA)
  a. 1 and 2 only
  b. 1 and 3 only
  c. 1, 2 and 3
  d. 1, 2, 3, and 4

  a. Blood leaving high units has a high PO2 and a low PCO2.
  b. Blood leaving low units has a low PO2 and a high PCO2.
  c. High units can compensate for high PCO2 levels from low units.
  d. High units can compensate for low PO2 levels from low units.

Answer to Question 1

ANS: D
The alveolar partial pressure of carbon dioxide, or PACO2, varies directly with the body's pro-duction of carbon dioxide (VCO2) and inversely with alveolar ventilation (VA). A decrease in alveolar ventilation occurs when the minute ventilation is inadequate, the dead space ventilation per minute is increased, or a / imbalance exists.

Answer to Question 2

ANS: D
However, the shape of the dissociation curves dictates that a high / unit can reverse the high PCO2 but not the low PO2.
