Answer to Question 1

ANS: C
Capnography is an excellent method to determine tracheal, rather than esophageal, intubation because only the lungs produce CO2.

Answer to Question 2

ANS: D
Beyond FIO2s of 0.50 to 0.60, most systems are unreliable because of the Haldane transfor-mation; therefore, any data derived from their use should accordingly be viewed skeptically.
