1. Color of Air Tank/Cylinder - Correct Answer: YELLOW
2. Color of O2 Tank/Cylinder - Correct Answer: GREEN
3. Color of the INTERNATIONAL O2 Tank/Cylinder - Correct Answer: WHITE
4. Color of CO2 Tank/Cylinder - Correct Answer: GREY
5. Color of (NO) Nitric Oxide Tank/Cylinder - Correct Answer: Blue Teal
6. Color of (He) Helium Tank/Cylinder - Correct Answer: BROWN
7. Color of Heliox (O2 & He) Tank/Cylinder - Correct Answer:
GREEN/BROWN
,8. Color of (N20) Nitrous Oxide "Laughing gas" Tank/Cylinder - Correct
Answer: LIGHT BLUE
9. Tank Size H/K Factor and Capacity - Correct Answer: Factor 3.14
Capacity (Cu Ft) 244
10.Tank Size E Factor and Capacity - Correct Answer: Factor .28
Capacity (Cu Ft) 22
11.(Duration of Flow) Formula - Correct Answer: PSI x's Tank Factor /
Patient Flow ( How many LPM the patient is on) = Duration of flow for the
tank.
12.Liquid O2 Formula - Correct Answer: Wt(lbs) * 344/ Patient Flow
13.What are the THREE classifications of Medical Gasses - Correct Answer:
1.) Laboratory Gasses ( ABG or PFT Lab)
2.) Therapeutic Gasses ( treatments for conditions)
3.) Anesthetic Gasses (Sedation or Laughing gas)
14.Air - Correct Answer: Supports Combustion/ Not Flammable
78% Nitrogen
21% 21.95% Oxygen
YELLOW Tank/Cylinder
Used to give Neb treatment by " little air compressors"
,15.OXYGEN (O2) - Correct Answer: Supports Combustion
Boiling point -183C ( turns to gas)
Colorless, odorless
GREEN Tank/Cylinder
WHITE International Tank/Cylinder
16.What are the TWO methods to Prepare Oxygen (O2) - Correct Answer:
1.) Fractional Distillation- 99% pure (FDA), Joule-Thompson Effect, Stored in
Cryogenic (cold) tanks, OR Metal Cylinders (Bulk O2)
2.) Physical Separation- A.) Molecular Sieve B.) Semipermeable Membrane
17.What is the Joule-Thompson Effect - Correct Answer: Air is filtered and
is liquefied by compression then cooled by Rapid expansion, Nitrogen is
used to cool gas. Water, CO2 and Pollutions are REMOVED
18.How does Physical Separation Work - Correct Answer: 1.) Molecular
Sieve- uses inorganic sodium aluminum silicate pellets to absorb Nitrogen,
makes 90% better, concentrators
2.) Semipermeable Membrane- Uses a Vacuum to pull air through
membrane, separating the Nitrogen, Makes 40%
19.CO2 (Carbon Dioxide) - Correct Answer: NON-Flammable/ NON-
Combustible
Treats Singultus (hiccups)
Used to calibrate ABG analyzer
Used during heart/lung bypass
GREY Tank color
, Colorless, odorless
20.What is Singultus - Correct Answer: Hiccups
21.(NO) Nitric Oxide - Correct Answer: Supports Combustion,Toxic, Non
Flammable, colorless
MAJOR Pulmonary VASOdilator
20-80 ppm (parts per million) combined with O2- Via Ventilator
***Hazards***
Methemoglobinemia- iron in the ferric form instead of the usual ferrous
form
22.What has the FDA approved for Infants with PPHN Persistent Pulmonary
Hypertension of the Newborn (Hypoxic Respiratory Failure) - Correct
Answer: (NO) Nitric Oxide, These baby's must have a Methemoglobinemia
test daily to prevent the over use
23.(He) Helium - Correct Answer: Non-Flammable/Non-Combustible
Second Lightest Gas
BROWN Tank
Used combined with O2 to treat LARGE airway obstructions
24.What are the Concentrations for Heliox
(He+O2) - Correct Answer: 70/30 He/O2
80/20 He/O2
60/40 He/O2
