Q

What is the free-floating valve?

A
  • Moves in the direction or “push” of gas flow
  • Prevents gas from leaking out of system
  • Found in DISS and dual hanger yoke systems

Q

The hanger yoke valve acts as a “___” valve

A

Safety valve

22
Q

The hanger yoke valve opens and closes with ___

A

Pressure (i.e.: free floating valve)

23
Q

The hanger yoke/free floating valve prevents a cylinder from…

A

Emptying into an empty cylinder or wall oxygen from entering a cylinder

24
Q

Failure to open the cylinder valve will result in…

A

No gas flow to the anesthesia machine

25
Q

What does a ball and spring valve do?

A
  • The ball and spring valve prevents the mixing of oxygen and nitrous oxide
  • Has oxygen fail safe pressure device—will automatically shut off nitrous oxide if oxygen pressure falls below a certain point
26
Q

Oxygen pressure must maintain at least ___ psig to keep the ball and spring valve open

A

25 psig

27
Q

Ball and spring valve senses ___ only, not flow delivery

A

Pressure

28
Q

How many diaphragm valves are on the anesthesia machine?

A

Only 2 of these valves on the anesthesia machine

29
Q

What are the 2 diaphragm valves on the anesthesia machine?

A
  • First stage regulator

- Second stage regulator

30
Q

What is the only role of the diaphragm valve?

A

To reduce pressure

31
Q

The first stage regulator reduces cylinder pressure to ___ psig

A

40-50 psig (intermediate pressure)

32
Q

The second stage regulator reduces pressure of 40-50 psig to ___ psig

A

16 psig (intermediate to low pressure)

33
Q

Who founded the first anesthesia school?

A

Agatha Hodgins

34
Q

Where was the first anesthesia school located?

A

Cleveland, Ohio

35
Q

What year was the first anesthesia school founded?

A

1915
