22
Q

what pressure system is the oxygen flush valve in

A

int

23
Q

5 tasks of oxygen in the AGM

A

proceeds to the fresh gas flowmeters, piers the oxygen flush, activates the fail safe device, activates oxygen low-pressure alarm, compresses the bellows of mechanical ventilators

24
Q

what kind of valve is the O2 flush valve

A

ball and spring

25
Q

what does the first stage regulator do

A

high system to int. cylinder pressure decreased to 40-50 PSI

26
Q

what does the second stage regulator do

A

intermediate to low. 40-50 to 16.

27
Q

what kind of valves are the regulators

A

diaphragm

First and Second stage regulators that reduce the pressure from high to intermediate to low

28
Q

what system are flow meter tubes in

A

low

29
Q

what system are vaporizers in

A

low

30
Q

what system are check valves in

A

low

valve between vaporizers and common gas outlet

31
Q

what system is the common gas outlet in

A

low

32
Q

hypoxic guard

A

nitrous oxide/ oxygen porportioning system

33
Q

thorpe tube has the largest diameter at the

A

top

34
Q

where is the free floating valves found

A

DISS and hanger yoke systems

35
Q

free floating valve opens with

A

pressure, and closes with pressure

36
Q

variable bypass vaporizers

A

one part goes thru system, some o2 goes thru without picking up gas

37
Q

what happens if the inspiratory valve sticks open

A

the exp volume will exhaust thru the insp limb and ETCO2 will be elevated. pt is rebreathing CO2

38
Q

what happens if exp valve sticks open

A

patient gets lower tidal volumes , hypoxic. due to the path of least resistance, the inspired volume will not enter the ETT but instead will bypass and exhaust the exp limb

39
Q

tightening the APL valve will ____ the pressure

A

increase

40
Q

APL valve function

A

adjusts the limit of pressure in the pt circuit and rebreathing bag

41
Q

do the fail safes check pressure or flow

A

pressure. if theres a pipeline crossover the pt can get the wrong gas
(ball and spring valve?)

42
Q

oxygen pressure failure device

A

shuts off and or porportionately reduces n20 flow if o2 pressure drops below 20

43
Q

hypoxia prevention safety device

A

proportioning device, prevents you from setting a hypoxic mixture with the flow control valves. limits n20 flow to 3 times o2 flow.

44
Q

Th oxygen flush valve delivers oxygen to pt at ____L/min

A

35-75L/min
may cause barotrauma
(pressurized at 40-50 PSI)
