1

Which gases can pass through the fresh gas inlet?

All of the gases.

2

The regulator or reduction valve reduces the psi to what value?

50 psi

3

Delivering oxygen and also possibly anesthetic gases as well as eliminating carbon dioxide is done by what system?

Patient Breathing System (PBS)

4

What are the 2 main types of patient breathing systems?

- Rebreathing
- Non-rebreathing

5

What should be done to a patient breathing system (PBS) prior to use?

Leak check

6

Which patient breathing system has a one-way circular pattern?

Rebreathing (circle) system

7

With which patient breathing system does the patient inhale the same anesthetic as they are exhaling?

Rebreathing (circle) system

8

What is the unit of measurement used in the flowmeter?

L/min

9

Which type of breathing system needs a form of CO2 absorption?

Rebreathing (circle) system

10

Why are rebreathing (circle) systems not good for smaller patients?

There are more components so there is an increased resistance for smaller patients.

11

A build up of CO2 can lead to what?

Acidemia

12

Rebreathing (circle) systems should be used for animals above what weight?

3 kg

13

A pediatric rebreathing hose should be used for patients under what weight?

15 lbs

14

What type of rebreathing hose is used for patients 15-300 lbs?

Standard adult circle hose

15

What are 2 types of hoses used with a rebreathing (circle) system?

- Y
- Universal F

16

Do circle system valves increase or decrease resistance to breathing?

Increase resistance to breathing

17

Circle system valve incompetence can lead to what?

Rebreathing

18

What can increased rebreathing lead to?

CO2 values going up causing an acidosis.

19

What does APL stand for?

adjustable pressure limiting

20

What is another name for a "pop-off" valve?

Adjustable Pressure Limiting Valve

21

What limits pressure build-up within the circuit?

APL/pop-off valve

22

Does an APL/pop-off valve need to be open or closed when administering a breath?

Closed

23

APL/pop-off valves should always be open except in what circumstances?

Delivering manual, controlled or assisted ventilation

24

What would happen if the APL/pop-off valve were closed when administering a breath?

Build up of pressure within the circuit could lead to barotrauma.

25

What measure pressure within the breathing circuit?

Breathing System Pressure Gauge

26

What is the breathing system pressure gauge typically located next to?

Flow meter

27

A breathing system pressure gauge should always read what unless what two events are occurring?

- Zero
- Performing leak checks or providing IPPV

28

The breathing system pressure gauge is measured in what units?

cm H2O

29

The oxygen cylinder pressure gauge is measured in what units?

PSI

30

The non-rebreathing system pressure gauge is measured in what units?

cm H2O
