How much pressure does a full O₂ cylinder contain? Correct Answer: 2200 psig
The "H" cylinder holds _____ cubic feet of O₂; while the "E" cylinder holds _____
cubic feet of O₂. Correct Answer: The "H" cylinder holds 244 cubic feet of O₂;
while the "E" cylinder holds 22 cubic feet of O₂.
What are the two types of safety releases on oxygen tanks? Correct Answer: 1.
Frangible disk (breaks at 3000 psig)
2. Fusible plug (melts at 208° - 220°)
There is a color code system for tanks of oxygen. Tell me what are the colors for
the following tanks:
1. Oxygen
2. Helium
3. CO₂
4. Nitrous Oxide
5. Cyclopropane
6. Ethylene
,7. Air Correct Answer: 1. Oxygen = green (white internationally)
2. Helium = brown
3. CO₂ = gray
4. Nitrous Oxide = light blue
5. Cyclopropane = orange
6. Ethylene = red
7. Air = yellow
A star next to the latest test date on an oxygen tank means the next test must
be done ______ years from that date. Correct Answer: A star next to the latest
test date on an oxygen tank means the next test must be done 10 years from
that date.
With a Thorpe flowmeter (or uncompensated flowmeter), back pressure does
what? Correct Answer: Gives a false reading. Flowmeter reading ins lower than
what the patient is actually receiving.
As opposed to a compensated flowmeter. This type will accurately display flow
when back pressure is applied.
Is a Bourdon gauge compensated or uncompensated? Correct Answer:
Uncompensated. This means back pressure gives a false reading. However, the
Bourdon gauge will display the same reading whether it is horizontal or vertical.
What is the O₂ delivery and flow rates for NASAL CANNULA? Correct Answer:
24% - 40%
,1-5 L/min
What is the O₂ delivery and flow rates for SIMPLE MASK? Correct Answer: 35% -
50%
5-10 L/min
What is the O₂ delivery and flow rates for PARTIAL REBREATHER? Correct Answer:
40% - 70%
8-15 L/min
What is the O₂ delivery and flow rates for NON-REBREATHER MASK? Correct
Answer: 60% - 100%
10-15 L/min
If the patient's VT is fluctuating and not consistent or the respiratory rate is above
25, what type of O₂ delivery device should you use? Correct Answer: High flow
(e.g. air entrainment mask, aerosol mask, or any device attached to a
nebulizer)
True / False
, Increasing the flow rate on high-flow devices will NOT increase FIO₂. Correct
Answer: True
What is the O₂ delivery and flow rates for AEROSOL MASK? Correct Answer: 21%
- 100%
8-15 L/min
Mist should be visible at all times to ensure adequate flow rates.
What is the O₂ delivery and flow rates for FACE TENT? Correct Answer: 21% - 40%
8-15 L/min
What is the O₂ delivery and flow rates for T-TUBE OR BRIGGS ADAPTOR? Correct
Answer: 21% - 100%
8-15 L/min
Adequate flows are ensured by visible mist flow out of the 50 mL reservoir at all
times.
What is the O₂ delivery and flow rates for TRACHEOSTOMY MASK? Correct
Answer: 35% - 60%
