Answer to Question 1

ANS: A
Phase 3 becomes indistinguishable when physiological dead space increases, as in chronic ob-structive pulmonary disease (COPD), and causes the capnogram to appear as it does in the figure. A cardiac arrest would lower the graph line to zero. Hyperventilation will decrease the alveolar plateau, but its shape would remain the same as a normal capnogram. A pulmonary embolism would also cause a drop in the alveolar plateau.

Answer to Question 2

ANS: B
The arterial-to-end-tidal partial pressure of carbon dioxide P(a-et)CO2 for tidal breathing should be approximately 4-6 mm Hg.
