Which of the following medical gases can be stored in cylinders as liquids at room
temperature?

Helium must always be combined with at least how much O2?

Which of the following mechanisms do all compressed gas cylinders use to avoid excessively
high buildup of cylinder pressure?

What is the change in state of a substance from liquid to gaseous form occurring below its
boiling point?

Department of Transportation (DOT) regulations require compressed gas cylinders to be
hydrostatically tested for leaks and expansion every how often?

Unlike CO2 or N2O, O2 cannot be stored as a liquid at room temperature but must be kept in
special cryogenic containers. Why is this so?

following devices would you select to control gas flow?

What is the fire-risk classification of both N and CO2?

What is the equilibrium condition in which a gas holds all the water vapor molecules that it
can?

During inspection of the shoulder of a compressed gas cylinder, you note a plus sign (+) next
to the test date. This indicates what about the cylinder?

Commerce, a gas cylinder that is color-coded brown and green should contain which of the
following?

Which device is used to reduce the pressure and control the flow of a compressed medical
gas?

If you have to deliver O2 to a patient directly from a bedside outlet station, which of the
following devices would you select?

What is the temperature at which the vapor pressure of a liquid equals the pressure exerted on
the liquid by the surrounding atmosphere?

What is the term for the ratio of the actual water vapor present in a gas compared with the
capacity of that gas to hold the vapor at a given temperature?
