The Bain circuit: (Select 2.)

Study on!!!
The Bain System is a modified Mapleson —
“Modified Mapleson D” = Bain System

In the Bain System Fresh gas enters the circuit through the —– tubing
Thin inner

In the Bain System Fresh gas enters the circuit through the thin inner tubing and exhaled gas exits via the —– tubing
Corrugated tubing

The outer corrugated tubing should be —– so you can assess the integrity of the inner tubing.
“transparent”
—– warms and humidifies the incoming fresh gas
Exhaled gas
The Bain circuit is useful for —– and —– ventilation
Spontaneous and Controlled
To prevent rebreathing, the FGF should be — times minute ventilation
2.5 times
Pitfalls of the Bain Circuit: It is possible that the inner tubing can become kinked or disconnected. This situation converts all of the corrugated tubing to —–
“dead space”
Pitfalls of the Bain Circuit: It is possible that the inner tubing can become kinked or disconnected. This situation converts all of the corrugated tubing to dead space, putting the patient at risk for
Hypercarbia
The —- test should be done as part of the pre-anesthetic checkout before using the Bain circuit
Pethick test
The Pethick test should be done as part of the pre-anesthetic checkout before using the Bain circuit. Steps include: (1). Occlude the —– at the patient end of the circuit
“elbow”
The Pethick test should be done as part of the pre-anesthetic checkout before using the Bain circuit. Steps include: (1). Occlude the elbow at the patient end of the circuit. (2). Close the —–valve
APL
The Pethick test should be done as part of the pre-anesthetic checkout before using the Bain circuit. Steps include: (1). Occlude the elbow at the patient end of the circuit. (2). Close the APL valve. (3). Use the —– valve to fill the circuit
Oxygen flush valve
The Pethick test should be done as part of the pre-anesthetic checkout before using the Bain circuit. Steps include: (1). Occlude the elbow at the patient end of the circuit. (2). Close the APL valve. (3). Use the oxygen flush valve to fill the circuit. (4). Remove the occlusion at the elbow while —– the circuit.
“flushing”
Interpretation of Results: If the inner tubing is patent, the —– effect will cause the reservoir bag to collapse
Venturi effect
Interpretation of Results: If the inner tubing is patent, the Venturi effect will cause the reservoir bag to collapse. The circuit is safe to use
True
If the inner tubing is occluded, the reservoir bag will remain —–. The circuit is not safe to use.
“inflated”
The Bain circuit: (Select 2.)

Delivers fresh gas through the inner tube
Is tested with the Pethick test
The Bain system uses a coaxial design, where: Fresh gas is delivered to the patient through the —- tube
“inner tube”
The Bain system uses a coaxial design, where: Fresh gas is delivered to the patient through the inner tube. Exhaled gas travels through the —– tube
“outer tube”
The inner tube is at risk for kinking and disconnection. The —- test should be performed as part of the pre-anesthetic checkout
Pethick test
The Bain system is a modified Mapleson —. It can be used for spontaneous as well as controlled ventilation.
