Answer to Question 1

ANS: C
Laboratory CO-oximeters measure all four types of hemoglobin by using separate wavelengths of light to identify each species, whereas pulse oximeters use only two wavelengths to quantify the amount of O2HB and HHB present.

Answer to Question 2

ANS: C
Barometers are used to measure atmospheric (barometric) pressure. Older ventilators incorporated an aneroid manometer into the ventilator circuit. Variable orifice pneumotachometers are used to measure flow. The devices that are used in the current ventilators today are the electromechanical transducers, which include piezoelectric transducers, variable capacitance transducers, and strain gauge transducers.
