Answer to Question 1

ANS: D
That is, the direct delivery of oxygen into the trachea reduces dilution with room air on inspira-tion because the upper airways (the anatomic reservoir) are filled with oxygen.

Answer to Question 2

ANS: C
The humidity bottle is not designed for high flows. When it is set to a high flow, the humidity bottle expands and whistles; in turn there is a greater likelihood that the oxygen flowmeter will pop off from the pressure source.
