1
Q

Match each breathing system with its classification.

A

Study on!!!

2
Q

The primary function of the breathing circuit is to deliver oxygen and anesthetic agent to the patient, while eliminating carbon dioxide to prevent

A

rebreathing

3
Q

Carbon dioxide is removed from the breathing circuit by —– with a high fresh gas flow

A

washout

4
Q

Carbon dioxide is removed from the breathing circuit by washout with a high fresh gas flow or through a chemical reaction with a

A

CO2 absorbent

5
Q

There are 4 classifications of breathing circuits:

A

open ,

semi-open,

semi-closed, and

closed

6
Q

There are 4 classifications of breathing circuits: open , semi-open, semi-closed, and closed. Although some texts no longer recognize this classification schema, others do. This makes it fair game for the NCE.

A

Thanks

7
Q

The —– breathing circuit is a non-contained system where the patient exchanges gas with the atmosphere.

A

Open breathing circuit

8
Q

The —– breathing circuit does not allow rebreathing of exhaled gas

A

Semi-Open breathing circuit

9
Q

In the Semi-Open breathing circuit, FGF is —– than minute ventilation

A

“greater”

10
Q

The —– breathing circuit allows rebreathing of exhaled gas

A

Semi-Closed breathing circuit

11
Q

In the Semi-Closed breathing circuit, FGF is —– than minute ventilation

A

“less”

12
Q

In the Semi-Closed breathing circuit, —– increase airway resistance

A

Unidirectional valves

13
Q

In the —– breathing circuit, there is complete rebreathing of exhaled gas

A

Closed breathing circuit

14
Q

The Closed breathing circuit Uses very low FGF

A

True

15
Q

In a Closed breathing circuit, the amount of gas that needs to be replaced is the sum of the patient’s oxygen consumption plus the amount of anesthetic agent that is absorbed by the patient

A

True

16
Q

In a Closed breathing circuit, since the volumes of inspired and expired gases are equally matched, gas does not exit the scavenger

A

True

17
Q

In a Closed breathing circuit, the APL valve is

A

“closed”

18
Q

In a Closed breathing circuit, the change in gas concentration is very slow as a result of a very low FGF

A

True

19
Q

In an Open breathing circuit, Rebreathing is

A

not allowed

20
Q

In an Open breathing circuit, a Reservoir is

A

not present

21
Q

Examples of Open breathing circuits include:

A

Insufflation

Simple face mask

Nasal cannula

Open drop

Q

In a Semi-Open breathing circuit, a Reservoir is

A

Present

24
Q

Mapleson circuit is an example of a —– breathing circuit

A

Semi-Open breathing circuit

25
Q

In a Mapleson circuit, FGF is dependent on

A

Design

26
