The concentration of oxygen delivered to the patient with an air-entrainment mask depends on which of the following?
 
  1. Flow of the oxygen exiting the jet nozzle
  2. Size of the jet nozzle outlet
  3. Size of the entrainment port
  4. Size of the Venturi mask
  a. 1, 2, and 3 c. 1, 2, and 4
  b. 2, 3, and 4 d. 3 and 4

Question 2

Theoretically, a nonrebreathing mask can deliver 100 oxygen, assuming that the mask fits ap-propriately on the patient's face and is the only source of gas being inhaled by the patient.
 
  However, in actual practice, the disposable nonrebreathing mask can deliver what percentage of FIO2?
  a. 0.30-0.50 c. 0.60-0.80
  b. 0.40-0.60 d. 0.24-0.50

Answer to Question 1

ANS: A
Oxygen flowing through the jet nozzle of an air-entrainment device drags in room air through the entrainment ports as a result of viscous, shearing forces between the gas exiting the jet nozzle outlet and the surrounding ambient air. The concentration of oxygen delivered to the patient, therefore, depends on the flow of oxygen exiting the jet nozzle, the size of the jet nozzle outlet, and the size of the entrainment ports.

Answer to Question 2

ANS: C
The discrepancy between disposable nonrebreathing masks and the original Booth-by-Lovelace-Bulbulian masks is primarily related to the fact that manufacturers usually supply disposable masks with one of the exhalation valves removed.
