25
Q

Refers to the diameter of the inner cannula (dual-cannula systems)

A

Inner diameter

26
Q

Determined by the ID of the tube itself (single-cannula tube system)

A

Inner diameter

27
Q

TRUE or FALSE

If the ID is too small, resistance through the tube increases and impacts the work of breathing

A

TRUE

28
Q

True or False
Tubes with extra proximal length (horizontal) are designed to accommodate the obese neck or neck masses that displace the trachea posteriorly

A

True

29
Q

True or False

Tubes with extra distal (vertical) length can be used to bypass areas of stenosis or malacia distal to the stoma

A

True

30
Q

Are ideal for patients who do not require mechanical ventilation

A

Uncuffed tubes

31
Q

True or False

Uncuffed tubes can bypass upper airway obstruction, allow for pulmonary toilet, and accommodate speech

A

True

32
Q

Designed to facilitate positive pressure ventilation

A

Cuffed tubes

33
Q

True or False

Most cuffs are designed to be high-volume/low-pressure cuffs to help mitigate the risk of tracheal stenosis

A

True

34
Q

Tracheal mucosa capillary perfusion pressure

A

25-30mmHg

35
Q

Cuff pressure greater than 25-30mmHg can result in

A

Ischemic necrosis—>stenosis

36
Q

Ideal for patients who need only intermittent postive pressure

A

Low -volume/high pressure (tight-to-shaft)

37
Q

Classifications of tracheotomy can be classified as

A
  1. Intraprocedural
  2. Early (<7 days)
  3. Late (>7 days)
38
Q

Intraprocedural complications:

A
  1. Airway fire
  2. Bleeding
  3. Pneumothorax/Pneumomediastinum
39
Q

The initiation and propagation of fire requires 3 things:

A
  1. Fuel source
  2. Energy source
  3. Oxidizing agent
40
Q

True or False

Intraoperatively, most bleeding is secondary to anterior vein injury or from the bleeding edge of the thyroid

A

True

41
Q

Potential mechanism (pneumothorax/pneumomediastinum)

A
  1. Direct injury to the pleura
  2. Dissection of air along the trachea
  3. Rupture of an alveolar bleb
42
Q

Early complications of tracheotomy

A
  1. Infection
  2. Tube obstruction
  3. Pressure ulcers
  4. Accidental decannulation
43
Q

True or False

Tracheotomy bypasses the natural warming and humidification provided by the nasal passages

A

True

44
Q

True or False

If the tube cannot be successfully placed through the tracheotomy, translaryngeal intubation should be attempted

A

True

45
Q

Late complications of tracheotomy

  2. Tracheoinnominate fistula
  3. Tracheoesophageal fistula
  4. Tracheocutaneous fistula
46
Q

True or False
When cuff pressure exceeds capillary perfusion pressure, the result is ischemic necrosis and chondritis of the underlying tracheal cartilages

A

True

47
Q

True or False

High-volume, low-pressure cuffs have been designed to mitigate tracheal stenosis

A

True

48
Q

True or false

Tracheoinnominate fistula occurs in approximately 0.7% of patients in both acute (<2 weeks) and chronic (>2 weeks)

A

True

50
Q

A sentinel bleeding event often, but not always, precedes massive hemorrhage

A

Tracheoinnominate fistula

51
Q

In 78% tracheoinnominate fistula, the event occurs between

  2. Malnutrition
  3. Radiation
  4. Steroid usage

53
Q

First priority in tracheoinnominate fistula/bleeding

54
Q

Definitive treatment of tracheoinnominate fistula/bleeding

A

Median sternotomy with ligation of the innominate artery

55
Q

True or False

The risk of fistula formation through the “party wall” is increased when large-bore NGT is also in place

A

True

56
Q

Tracheoesophageal fistula is best managed by

A

Interposition of viable tissue between the membranous trachea and the esophagus

57
Q

True or False
Of patients who have a tracheotomy tube in place for more than 4 months, 70% will have a persistent tracheocutaneous fistula as a result of epithelialization of the tract

A

True

58
Q

True or False

A history of radiation exposure or the use of a Bjork flap increases the risk of a persistent tract after decannulation

A

True

59
Q

Patient who had had an open tracheostomy could have the first tracheostomy tube change by physicians between days 3 and 5

A

True

60

A

True

61
Q

Candidates for decannulation should be assessed for

A
  1. Level of consciousness
  2. Respiratory status
