15 Questions
What is the function of wall/station outlets in a piping system?
To allow for the connection of various types of equipment to the pipe system
What is the primary advantage of a piping system for delivering medical gases?
Provide a continuous and uninterrupted supply of medical gases
What is the purpose of riser lines in a piping system?
To transport gases from the main line to upper floors or elevated areas
What is the purpose of alarms in a piping system for medical gases?
To warn of a decrease in pressure or interruptions of flow
What happens when the primary shut-off is open?
Plunger is depressed, opening the outlet holes for gas flow
What is the function of the secondary shut-off valve?
Preventing pressurized gas from escaping into the room
What is the state of the plunger in the closed position of the primary shut-off?
Not depressed, outlet holes are occluded by the stem
What is the purpose of the spring behind the secondary shut-off valve?
Activating the secondary shut-off valve when the primary shut-off is removed
What precaution should be taken to prevent rapid pressure changes when using a gas cylinder?
Slowly open the cylinder valve
Why is it important to ensure that the regulator or reducing valve is in the off or closed position when not in use?
To prevent failure of the reducing valve
What risk is increased in the presence of O2 when rapid decompression and recompression occur?
Risk of igniting combustible materials
What happens when a less dense gas is used in a flowmeter calibrated for a denser gas?
The flowmeter will indicate a lower flow rate than the actual flow rate of the less dense gas
What correction factors are applicable for Heliox (He/O2) when using oxygen flowmeter?
1.6 x 10: 16L/min for 70% He/30% O2 and 1.8 x 10: 18L/min for 80% He/20% O2
How does the use of a less dense gas affect the gas flow indicated by the flowmeter?
More gas will leave the flowmeter than is indicated on the flowmeter
What is the impact of using a less dense gas on the lifting of the float in a flowmeter?
More molecules of gas are required to lift the float
