Q

What are the 2 Tracheostomy Methods

A

Surgical tracheostomy
- permanent or temporary and is performed in OR
- incision made between the second and third
tracheal rings 4 5 cm in length.

Percutaneous Tracheostomy
- temporary and is performed in the ICU etc.
- a small hole between the first and second or
second and third tracheal rings is created then
dilated using specialised equipment.

37
Q

What is the problem of kinking of TT

A

–> suction catheter cannot pass through

38
Q

What is the problem of herniation?

A

when old trach tube with low elasticity is overinflated, the cuff might fold on itself, obstructing the bottom of the TT

39
Q

What are the 4 ways to check for tube patency?

A
  1. pass suction catheter through trach tube to measure the length that is or isn’t blocked
  2. check the inner cannula
  3. squeezes BVM to assess patient compliance and resistances
  4. auscultate to listen for abnormal breath sounds at the apices of lung (crackles, wheezing)
40
Q

How can TT position affect the passage of suction catheter ?

A
  1. TT sitting up the tracheal wall
    - ->reposition the flange
  2. Cuff herniation
    - ->deflate the cuff and pass the catheter through
    - ->if it passes, reinflate the cuff to reassess herniation
    - ->if it doesnt pass , code blue, prepare for a new TT
41
Q

45
Q

What are 2 types of Tracheostomy Speaking Valves?

A

Passy-Muir: non vented

Passy-Muir: ventilated

46
Q

how does the passy muir work

A

Attaches with 15mm connector
Valve opens on inspiration to allow air into lungs
Valve closes on exhalation and redirects flow into
trachea and up through vocal cords to permit speech

47
Q

What is the advantages of speak valve?

A

Eliminates need for finger occlusion to talk
allow for phonation
Restores intrinsic PEEP
Improves swallow

48
Q

What kind of TT can speaking valve not used with?

A

A speaking valve must never be placed
on the 15mm connector of a nonfenestrated tube when the cuff is
inflated as the patient will not be able to
exhale.

49
Q

What kind of TT can speaking valve used with?

A

on a uncuffed TT with or without fenestration OR

on a cuffed tube with fenestration

50
Q

What are the contraindication to speaking valve

A 
 Inability to tolerate cuff deflation
--> high risk of aspiration
 Airway obstruction
 Unstable medical/pulmonary status
 Laryngectomy
-->patient can only exhale with the LT 
 Severe anxiety/cognitive dysfunction
 Severe tracheal/laryngeal stenosis
-->patient wont be able to exhale as airway becomes more narrow 
 End stage pulmonary disease
 Excessive secretions 
-->aspiration
51
Q

How does a Speaking Trach Tube work?

A 
requires secondary gas source
pt uses thumb port control
to permit gas to flow out a special port above the cuff and up through
vocal cords for speech
patient can speak during
inspiration and
exhalation
52
Q

what is a cork and how does it work?

A

a plug in the proximal end of trach tube
Patient must now inhale and exhale
entirely through upper airway

53
Q

What equipment is needed for changing trach tube?

A
  • difficult airway cart
  • intubation kit
  • smaller TT
  • trach change box
  • towel or pillow
  • PPE
  • BVM
  • suctioning
  • ->suction catheter and yankeur
54
Q

Where to suction when performing a trach change

A
  1. inside the tube
  2. suction via the subglottic drainage port
  3. if TT doesn’t has subglottic drainage port, need yankeur to suction above cuff
55
Q

What are the progression of weaning?

A
  1. cuffed
  2. Cuffed fenestrated
  3. cuffless
    - ->passy muir
    - ->cork
  4. Cuffless fenestrated
56
Q

how does downsizing work for weaning?

A

allow more surface area for patient to breath via the upper airway

57
Q

how does corking help with weaning?

A
  • cuff is deflated with corking

- patient has to breath via the upper airway

58
Q

What are the criteria for decannulation?

A
  • downsized to smaller tube and/or change to cuffless trach tube to encourage more use of upper airway
  • successful corking trials (may require
    intermediate step by using one way speaking valve)
59
Q

What is the outcome of speaking valve in place?

A
  • allow for phonation
  • patient can work on their inspiratory muscle
  • restores intrinsic Peep
  • phonation
  • helps with coughing and swallon because larynx can close tightly
60
Q

where is speaking value must not be placed?

A 
A speaking valve must never be placed
on the 15mm connector of a non
fenestrated tube when the cuff is
inflated as the patient will not be able to
exhale.
61
Q

What is the precauton of corking?

A

making sure the cuff is deflated or cuffless

62
Q

What type of O2 therapy can i use for speaking valve?

A

high flow trach mask

O2 adjuncts: low flow O2 that enrich the speaking valve

63
Q

What type of O2 therapy can i use for cork

A
  1. face mask

2. nasal prong

64
Q

What are the Patient assessment prior to

decannulation

A
  • Resolution of condition
  • Adequate LOC
  • Effective cough
  • Able to manage secretions
  • Adequate oxygenation
  • ->patient shouldn;t need a fio2 of 50 or 60 percent as that means their saturation isn’t optimized for decannulation
  • Swallow intact
  • Able to tolerate trach tube occlusion
65
Q

What are the steps of deccannulation?

A
  1. Mechanical ventilation no longer required

2. Tolerate tracheostomy tube occlusion

66
Q

What is the step of patient dont Tolerate tracheostomy tube occlusion

A

Fiberoptic airway management; complex airway management

67
Q

What is the step after Fiberoptic airway management; complex airway management?

A

check airway patency reestablishment

If yes–> decannulation

If no –> long term trach tube

68
Q

How does TT prevent swollening?

A

Tracheostomy tube prevents normal upward movement of the larynx during swallowing and hinders glottic closure
–> lead to aspiration

69
Q

How to facilitate effective feeding with TT?

A

Keep head elevated to 45 during periods of

tube feeding

70
Q

What are the Speech language pathologist

assessments?

A
  • evaluation of swallow and airway
    protective mechanisms
  • Blue Dye Test
71
Q

how does the blue dye test work?

A
  1. patient swallow a
    teaspoon of blue dyed
    fluid/paste

2.then observe for risk signs

72
Q

What are the risk signs that patient larynx doesnt close tightly?

A
  1. blue dye is found in trach suctioning
  2. significant decrease in O2 sat levels
  3. immediate or delayed coughing
73
Q

What is the action if there are risk signs ?

A

need to reinflate the cuff because larynx isn’t completely closed, thus there is still risk of aspiration

74
Q

What are some disadvantages of jackson tube

Q

What is a tracheal button?

A
  • it maintains airway patency

- fit from skin to just inside the anterior wall of the tracheal

79
Q

what is the purpose of a tracheal button?

A
  • used last step in the weaning process
  • has an outer plug that can completely close off the “button” airway and allow you to breathe, talk and cough normally via the upper respiratory trach
