2025 QUESTIONS AND CORRECT ANSWERS GRADED A+
VERIFIED SOLUTIONS BRAND NEW
What is the purpose of the pin index safety system - CORRECT
ANSWER✔✔prevent interchangeability of cylinders on the
cylinder yoke, two pins on the yoke correspond with two holes on
the cylinder valve
Combinations to O2, N2O, Air, CO2 pin index safety system -
CORRECT ANSWER✔✔Air - 1,5
O2 - 2,5
N2O - 3,5
CO2 - 1,6
What material are hospital pipeline made out of - CORRECT
ANSWER✔✔Copper
The pressure in the anesthesia machine is 2000 psi (T or F) -
CORRECT ANSWER✔✔False
What does the DISS prevent - CORRECT ANSWER✔✔
interchangeability of gas hoses
Pipe line systems - CORRECT ANSWER✔✔Primary source for
the anesthesia gas machine
- At 50 psi at
- cylinder pressure is at 45 psi
- anesthesia machine will high to low pressure
- turn off cylinders after machine check
,Diameter index safety system (DISS) - CORRECT ANSWER✔✔
Every gas has a different threading
The anesthesia machine high pressure side is exposed to the wall
flow or cylinder flow - CORRECT ANSWER✔✔Cylinder flow
-hanger yoke
-yoke block
-cylinder pressure gauge
-cylinder pressure regulator
what is the function of the cylinder crush gasket - CORRECT
ANSWER✔✔prevent leaking, reduces frictional flow
What type of valve is in a hanger yoke valve - CORRECT
ANSWER✔✔floating check valve, prevents transfixing of tanks
First stage regulator - CORRECT ANSWER✔✔- on the high
pressure side
- also known as a pressure reducing valve, reducing regulator or
regulator valve
- connects a gas from a variable pressure within the gas cylinder
to a lower more constant working pressure suitable for use in the
anesthesia machine
What is inside a first stage regulator - CORRECT ANSWER✔✔-
Valve seat
- Diaphragm
- adjustment screw and spring
What machines have 2nd stage regulators - CORRECT ANSWER
✔✔Omeda/GE/Datex
T or F ASTM standard that anesthesia machines have to be
turned on by on switch - CORRECT ANSWER✔✔True
, Second stage regulators - CORRECT ANSWER✔✔- Some
machines have reducing devices upstream of the nitrous oxide
and oxygen
- Receive gas from either the pipeline or the cylinder reducing
device
- reduces pressure to 26 psi for N2O and 14 psi for O2 (exams
12-16 psi)
- eliminates fluctuations in pressure supplied to the flow indicator
caused by fluctuations in pipeline pressure
- by reducing the pressures below the normal fluctuation range,
the flow will remain more constant
Does Dragor have a 2nd stage regulator - CORRECT ANSWER
✔✔No
O2 flush valve - CORRECT ANSWER✔✔- a separate line to the
oxygen flush valve comes from a common source to the hospital
pipeline DISS and cylinder yokes
- bypass valve directly from the pipeline inlet or cylinder regulator
- Also called oxygen bypass or emergency oxygen
T or F you never want to put O2 with newer machine - CORRECT
ANSWER✔✔False
Does the O2 flush valve bypass the vaporizers - CORRECT
ANSWER✔✔yes
How much direct flow does the O2 flush valve deliver -
CORRECT ANSWER✔✔35-75 L/min
Which type of flush valve is most commonly found on machines
without kettle type vaporizers - CORRECT ANSWER✔✔Type III.
Consists of a button and stem connected to a pin and ball. When
