The Bain circuit: (Select 2.)

A

Study on!!!

2
Q

The Bain System is a modified Mapleson —

A

“Modified Mapleson D” = Bain System

3
Q

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

A

Thin inner

4
Q

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

A

Corrugated tubing

5
Q

The outer corrugated tubing should be —– so you can assess the integrity of the inner tubing.

A

“transparent”

6
Q

—– warms and humidifies the incoming fresh gas

A

Exhaled gas

7
Q

The Bain circuit is useful for —– and —– ventilation

A

Spontaneous and Controlled

8
Q

To prevent rebreathing, the FGF should be — times minute ventilation

A

2.5 times

9
Q

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 —–

A

“dead space”

10
Q

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

A

Hypercarbia

11
Q

The —- test should be done as part of the pre-anesthetic checkout before using the Bain circuit

A

Pethick test

12
Q

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

A

“elbow”

13
Q

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

A

APL

14
Q

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

A

Oxygen flush valve

15
Q

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.

A

“flushing”

16
Q

Interpretation of Results: If the inner tubing is patent, the —– effect will cause the reservoir bag to collapse

A

Venturi effect

17
Q

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

A

True

18
Q

If the inner tubing is occluded, the reservoir bag will remain —–. The circuit is not safe to use.

A

“inflated”

19
Q

The Bain circuit: (Select 2.)

A

Delivers fresh gas through the inner tube

Is tested with the Pethick test

20
Q

The Bain system uses a coaxial design, where: Fresh gas is delivered to the patient through the —- tube

A

“inner tube”

21
Q

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

A

“outer tube”

22
Q

The inner tube is at risk for kinking and disconnection. The —- test should be performed as part of the pre-anesthetic checkout

A

Pethick test

23
Q

The Bain system is a modified Mapleson —. It can be used for spontaneous as well as controlled ventilation.

A

Mapleson D (not A)
