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

22
Q

The hanger yoke valve opens and closes with ___

Study These Flashcards
A

Pressure (i.e.: free floating valve)

23
Q

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

Study These Flashcards
A

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

24
Q

Failure to open the cylinder valve will result in…

Study These Flashcards
A

No gas flow to the anesthesia machine

25
What does a ball and spring valve do?
- 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
Oxygen pressure must maintain at least ___ psig to keep the ball and spring valve open
25 psig
27
Ball and spring valve senses ___ only, not flow delivery
Pressure
28
How many diaphragm valves are on the anesthesia machine?
Only 2 of these valves on the anesthesia machine
29
What are the 2 diaphragm valves on the anesthesia machine?
- First stage regulator | - Second stage regulator
30
What is the only role of the diaphragm valve?
To reduce pressure
31
The first stage regulator reduces cylinder pressure to ___ psig
40-50 psig (intermediate pressure)
32
The second stage regulator reduces pressure of 40-50 psig to ___ psig
16 psig (intermediate to low pressure)
33
Who founded the first anesthesia school?
Agatha Hodgins
34
Where was the first anesthesia school located?
Cleveland, Ohio
35
What year was the first anesthesia school founded?
1915
