Answer to Question 1

ANS: D
The area under the single-breath carbon dioxide (SBCO2) curve represents alveolar volume. This is known as phase 3 on the SBCO2 curve. Phase 1 is the anatomical dead space volume. Phase 2 is a transitional phase between anatomical dead space and alveolar volume.

Answer to Question 2

ANS: C
The end-tidal carbon dioxide (EtCO2) is represented by the very end of the waveform. The alve-olar ventilation is represented by the area under the curve, which is X. The alveolar dead space is represented by the difference between the arterial partial pressure of carbon dioxide (PaCO2) and the EtCO2 line, which is Y. The airway dead space is represented by Z.
