Answer to Question 1

ANS: A
The sensitivity of the impedance pneumograph can be adjusted by the operator to prevent false alarms because of changes in impedance caused by movement instead of by changes in respira-tion.

Answer to Question 2

ANS: D
Four major factors influence the PACO2CO2 production, perfusion of the lungs, diffusion, and ventilation. The balance of these four components represents the total transport and elimination of CO2.
