Answer to Question 1

ANS: B
Electrical analyzers use changes in current flow through wires to measure the concentration of oxygen. Contaminant gases can dissipate heat at different rates than oxygen and nitrogen, so, if gases other than oxygen and nitrogen are present, this can lead to erroneous fractional inspired oxygen (FIO2) levels.

Answer to Question 2

ANS: B
Raw averages 2 to 5 cm H2O/L/s.
