A. left, right *Not used as often* *Ericksen - when we use a **right DLT **we are doing surgery on the **left lung** *

Double-lumen tubes are placed similarly to a standard ETT but are more difficult due to ______ and ______. A. length, flexibility B. stiffness, size C. color, shape D. diameter, weight

B. stiffness, size

When advancing a double-lumen tube through the larynx, the tip should be angled ______ into the trachea. A. posteriorly B. laterally C. anteriorly D. medially

C. anteriorly

After the bronchial cuff passes the cords, the tube should be turned ______ degrees. A. 45 B. 60 C. 90 D. 180

C. 90 *Bronchial portion points toward the appropriate bronchus*

double lumen tube Verification of the location of the bronchial port should be done with: A. Direct visualization B. X-ray C. RSI Ultrasound D. Fiberoptic scope

D. Fiberoptic scope

The blue bronchial cuff should be just below the ______ in the appropriate bronchus. A. trachea B. carina C. epiglottis D. larynx E. pharynx

B. carina

# True or False The inflation of a bronchial ballon should be done under direct visualizaiton to verify proper placement

True *Fiberoptic scope*

Ensure the bronchial cuff does not ______ over the carina. A. inflate B. collapse C. herniate D. deflate

C. herniate

To isolate a lung with a double lumen tube, you can:Select 2 A. Deflate the bronchial cuff B. Clamp the tracheal connector C. Deflate the tracheal cuff D. Clamp the bronchial connector E. Rotate the double-lumen tube

B. Clamp the tracheal connector D. Clamp the bronchial connector *Test this out before the surgeon gets into the room. *

What is a common cause of unsatisfactory lung collapse when using a Double-Lumen Tube (DLT)? A. Tube too distal in airway B. Bronchial lumen in wrong mainstem C. Tube is too cephalad in airway D. Inadequate suction

B. Bronchial lumen in wrong mainstem *due to malposition * *Tube is too **proximal** in airway*

If the bronchial lumen is in the wrong mainstem, the recommended corrective measure is ______________. A. Reinsertion B. Using a fiberoptic bronchoscope C. Switching to a single-lumen tube D. Providing PEEP to the non-dependent lung

A. Reinsertion

A tube that is too proximal in the airway should be corrected using a ______________. A. Reinsertion B. Using a fiberoptic bronchoscope C. Switching to a single-lumen tube D. Providing PEEP to the non-dependent lung

B. Using a fiberoptic bronchoscope

When dealing with hypoxemia during DLT use, what factors need to be considered in patients with comorbidities? (Select 2) A. PEEP to the dependent lung B. Intermittent one-lung ventilation C. Increasing FiO2 D. Intermittent two-lung ventilation E. PEEP to the independent lung

A. PEEP to the dependent lung - *due to lung dz* D. Intermittent two-lung ventilation - *talk to the surgeon. Want to prevent V/Q mismatch* *Hypoxemia can also be caused my malpositioned tube - must be reinserted*

In which scenarios is a DLT is NOT advisable and a bronchial blocker should be used instead? (Select 5) A. Nasal intubation B. Supraglottic stenosis C. Patients with tracheostomy D. Easy intubation E. Single-lumen tube already in place F. Subglottic stenosis G. Difficult intubation H. Oral intubation

A. Nasal intubation C. Patients with tracheostomy E. Single-lumen tube already in place - F. Subglottic stenosis -*harder time to get DLT down* G. Difficult intubation - *use a normal ETT and then place a bronchial blocker*

# True or False It is ok to use a Double Lumen tube for continued postoperative intubation

False *If patient needs continued postoperative intubation, keep them asleep and switch out to normal ETT*

Bronchial blockers can block a segment of lung without __________ the entire lung, a task that cannot be done with a DLT. A. Collapsing B. Ventilating C. Obstructing D. Isolating E. Intubating

D. Isolating *CANNOT be done with a DLT only a bronchial blocker*

Which anatomical feature makes the use of bronchial blockers difficult? A. Low right upper lobe bronchus takeoff B. High right upper lobe bronchus takeoff C. Narrow trachea D. Wide left mainstem bronchus

B. High right upper lobe bronchus takeoff *May still be able to use bronchial blocker...*

What is a potential complication during surgery when using bronchial blockers? A. Tube displacement B. Fixation by staples C. Vocal cord damage D. Increased mucus production

B. Fixation by staples *Tell surgeon nicely to remove them*

What difficulties are associated with the use of bronchial blockers? (Select 4) A. Left upper lobe bronchus takeoff is high B. Tracheal bronchus C. Fixation by staples during surgery D. Perforation by suture needle E. Perforation by instrumentation F. Increased secretion clearance

B. Tracheal bronchus *- might need a second bronchial blocker or DLT* C. Fixation by staples during surgery D. Perforation by suture needle E. Perforation by instrumentation *Can happen with double lumen tube, but they are stiffer and more compliant*
