Q

Reasons you may use an endobronchial tube during surgery?

A

Infection, hemorrhage (disease or trauma) call for the isolation of the right + left lungs
Parynchema: provide unilateral support (oxygenation + ventilation to one lung)

Q

Anatomical position of the LLL in relation to the LUL?

A

LLL is posterior to LUL

23
Q

In which CXR view can you best visualize the RML?

A

Posterior + lateral

24
Q

Name three devices that we use in one-lung ventilation:

A

Endobronchial tube
Integrated ETT-bronchial blocker
ETT + bronchial blocker

25
A univent ETT is an example of:
an integrated ETT-bronchial blocker
26
Example of integrated ETT-bronchial blocker?
Univent ETT
27
Two examples of bronchial blockers that are to be used in conjunction with (but are not integrated parts of) an ETT?
Arndt device | Rusch endobronchial blocker
28
Arndt device + Rusch endobronchial blocker are two examples of:
ETT + bronchial blocker
29
What aspect of the double lumen tube separates the lungs from the environment?
Tracheal cuff
30
Purpose of tracheal cuff?
Separates the lungs from the environment
31
Purpose of endobronchial cuff?
Separates the two lungs from each other
32
What aspect of the double lumen tube separates the two lungs from each other?
Endobronchial cuff
33
Distinguishing feature of Right-sided double lumen ETT?
It has a ventilation slot for the RUL (make sure it is placed at the level of the RUL).
34
In a double lumen tube, what is the purpose of one lumen ending in the trachea + the other in a single lung?
We can control whether or not we ventilate both lungs at once (trachea) or one lung at a time (lung).
35
Method of visualization when placing EBT?
FFOB
36
Double lumen tubes are sized based on:
height
37
How do you confirm that you have successful placed a double lumen tube without the use of FFOB?
Clamp one lung off; when you ventilate, you should hear breathing sounds on one side but not the other
38
Which endobronchial tube has a clear lumen and a blue lumen? Which is the blue lumen?
Broncho-Cath Blue = bronchial
39
What color is the proximal balloon on a Broncho-Cath?
Clear
40
What color is the distal balloon on a Broncho-Cath?
Blue
41
What is a univent?
A conventional ETT with integrated bronchial blocker
42
The OD of a normal ETT is reflected in what aspect of a Univent?
OD
43
On a Univent, which balloon is blue?
The pilot balloon of the tracheal cuff.
44
Which endobronchial tube has a distal end with an ETT cuff and two lumens?
Univent (integrated ETT + bronchial blocker)
45
The ETT proximal end of a Univent has:
15 mm circuit connector ETT cuff inflation system Blocker port
46
The bronchial blocker proximal end of a Univent has:
Blocker inflation system Blocker port Blocker locking mechanism
47
Which endobronchial tube requires the use of a fiberoptic scope as an introducer?
Arndt endobronchial blocker
48
How does the Ardnt endobronchial blocker relate to an ETT?
It has a special connector that is compatible with the ETT: use that connector as a port of sorts to thread the Arndt device along with the fiberoptic scope.
49
Which endobronchial blocker has two proximal balloons, a radiopaque shaft, and bifurcated distal extensions/
Rusch endobronchial blocker
50
The distal end of which endobronchial blocker is Y-shaped?
Rusch
51
Which endobronchial blocker has a camera and light source, thereby eliminating the need for FFOB assistance?
ETView Medical VivaSight
52
Air volume required to inflate bronchial cuff?
6-7 cc
53
When you switch from one-lung ventilation to two-lung ventilation, what are some changes you should make to your ventilation settings?
Change your rate and tidal volumes (therefore minute ventilation) to prevent volutrauma.
54
If a patient starts to desaturate during one-lung ventilation, what are some things you can do?
100% O2 | Apply CPAP to non-ventilated lung.
