Oxygen Delivery Devices Questions with Correct Answers (Grade
A+)
Question 1: Simple mask: advantages
Answer: Quick and easy to setup and apply
Question 2: Simple mask: disadvantages
Answer: Nonspecific FiO2 (Dependant on patients inspiratory flows) Maximum FiO2 estimated at .50 Not
intended for long term use.
Question 3: Simple mask: watch for
Answer: Flow rates set less than 5 lpm may cause CO2 rebreathing
Question 4: Aerosol mask: advantages
Answer: Administers a specific FiO2. (Determined by air entrainment port on nebulizer) High humidity
output
Question 5: Aersol mask: disadvantages
Answer: Nebulizer is noisy Oxygen flow through the nebulizer is restricted, therefore a special setup is
required to administer FiO2 > .50. Constant rainout of humidity in tubing can alter FiO2.
Question 6: Aersol mask: watch for
Answer: Temptation to minimize noise by decreasing flow on flowmeter
Question 7: Venturi mask: advantages
Answer: Administers a specific FiO2. (Determined by air entrainment adaptor on end of mask.) Quiet
Question 8: Ventrui mask: disadvantages
Answer: FiO2 only available according to mask adapters. .24, .28, .31, .35, .40 and .50
Question 9: Ventrui mask: watch for
Answer: Do not cover the air entrainment ports on the mask adaptors with bed linen or patients clothes
(alters FiO2). Color coded adaptors are not universal. Different companies use different colors
