Match each breathing system with its classification.

Study on!!!
The primary function of the breathing circuit is to deliver oxygen and anesthetic agent to the patient, while eliminating carbon dioxide to prevent
rebreathing
Carbon dioxide is removed from the breathing circuit by —– with a high fresh gas flow
washout
Carbon dioxide is removed from the breathing circuit by washout with a high fresh gas flow or through a chemical reaction with a
CO2 absorbent
There are 4 classifications of breathing circuits:
open ,
semi-open,
semi-closed, and
closed
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.

The —– breathing circuit is a non-contained system where the patient exchanges gas with the atmosphere.
Open breathing circuit
The —– breathing circuit does not allow rebreathing of exhaled gas
Semi-Open breathing circuit
In the Semi-Open breathing circuit, FGF is —– than minute ventilation
“greater”
The —– breathing circuit allows rebreathing of exhaled gas
Semi-Closed breathing circuit
In the Semi-Closed breathing circuit, FGF is —– than minute ventilation
“less”
In the Semi-Closed breathing circuit, —– increase airway resistance
Unidirectional valves
In the —– breathing circuit, there is complete rebreathing of exhaled gas
Closed breathing circuit
The Closed breathing circuit Uses very low FGF
True
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
True
In a Closed breathing circuit, since the volumes of inspired and expired gases are equally matched, gas does not exit the scavenger
True
In a Closed breathing circuit, the APL valve is
“closed”
In a Closed breathing circuit, the change in gas concentration is very slow as a result of a very low FGF
True
In an Open breathing circuit, Rebreathing is
not allowed
In an Open breathing circuit, a Reservoir is
not present
Examples of Open breathing circuits include:
Insufflation
Simple face mask
Nasal cannula
Open drop
In a Semi-Open breathing circuit, Rebreathing is
not allowed
In a Semi-Open breathing circuit, a Reservoir is
Present
Mapleson circuit is an example of a —– breathing circuit
Semi-Open breathing circuit
In a Mapleson circuit, FGF is dependent on
Design
The Circle system is an example of a —– breathing circuit
Semi-Open breathing circuit
In a semi-open Circle system, FGF is —– Minute ventilation
“higher than”
In the Semi-Closed breathing circuit, Rebreathing is —–
Present (Partially)
In the Semi-Closed breathing circuit, a Reservoir is —–.
Present
The Circle system is an example of a —– breathing circuit
Semi-Closed breathing circuit
In a semi-closed Circle system, FGF is —– Minute ventilation
“lower than”
In a Closed breathing circuit, Rebreathing is —–
Present (complete)
In a Closed breathing circuit, a reservoir is —–
Present
A Circle system with very low FGF and APL closed is an example of a —– breathing circuit
Closed breathing circuit
Insufflation is an example of a —– breathing circuit
Open breathing circuit
A Simple face mask is an example of a —– breathing circuit
Open breathing circuit
A Nasal cannula is an example of a —– breathing circuit
Open breathing circuit
An Open drop is an example of a —– breathing circuit
Open breathing circuit
Match each breathing system with its classification

Open + No rebreathing and no reservoir
Semi-open + No rebreathing with a reservoir
Semi-closed + Partial rebreathing with a reservoir
Closed + Complete rebreathing with a reservoir
