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.
