Q

Two main functions of an obturator

A

To help place outter cannula into stroma and decrease chance of trauma to the trachea. ***Inner cannula is taken out while obturator is used to place.

Q

Most important thing to do when placing someone onto theventilator or back on a ventilator

A

Make sure pressures and volumes are good. Meaning if you are giving them 400ml TV you should be getting 400ml back.

Q

How can you prevent stenosis?***

A

Ensure that the trach ties are snug and not too loose. If it is loose it will allow the cannula to move around and cause damage inside. (can occur in multiple areas)

Q

A TE fistula is caused by what? And what is the primary way to diagnose this?

A

Caused from increased cuff presures of long term trachs. A fistula will cause frequent aspiration

Q

RT will typically change out trach, but when will the physician do it instead?

A

If its less than 5 days old, pt is unstable, or edema around the site.

Q

Two safety factors to keep in mind with XLT

DO NOT take to MRI

23
Q

MAin reason to use XLT

A

It is intended to be temporary until a custom sized one can be made

24
Q

What pt is an XLT proximal typically used for?

A

Usually very obese people because the proximal side is longer to reach through the extra neck fat/tissue

25
Q

XLT distal would be used for what pt?

A

A pt with an abnormally long trachea

26
Q

Hi-Lo Trach purpose

A

Helps prevent VAP because it has continuous suction above the trach. Has a cuff that can handle higher pressures (up to 40cmH2O)

27
Q

Standard settings for Hi-Lo Trach

A

continuous suction set at -20cmH2O, cuff can inflate to 40cmH2O.

28
Q

What does the fenestrated trach help with?

A

It acts as a normal trach for a ventilator with inner cannula in. If you take this inner cannula out, the patient can attempt to breath normally through their upper airway thanks to holes in the fenestrated trach.

29
Q

What is the main purpose of a fenestrated cannula?

A

Helps person wean after no longer being on ventilator

30
Q

How can a fenestrated cannula cause granular tissue?

A

if the inner cannula is kept out too long, the tracheal tissue can grow into the hole located on the outter cannula.

31
Q

How do you suction someone with a fenestrated cannula?

A

Remove the plug/cap and replace the inner cannula in order to hook up to mechanical ventialtion

32
Q

Which Trachs do you not want to take to MRI?

A

Jackson and XLT

33
Q

Which cuff would you record a volume instead of a pressure?

A

Bivona TTS

34
Q

Doesn’t have a pilot balloon, port is closed during insertion

A

Wilkenson/Bivona foam cuff. When it is placed, the port is opened and cuff self inflates

35
Q

What is the steps of troubleshooting a trach?

A
  1. DEFLATE CUFF AND O2
  2. Try to pass suction catheter down trach to asses obstruction
  3. Pull out inner cannula to look for obstruction
  4. Replace the trach (spare at bedside)
36
Q

Why do you need to deflate cuff prior to placement of a passy-muir valve

A

If you dont, they will inhale air, and then wont be able to exhale the air due to the inflated cuff and the one way valve located on the valve on the outside.

37
Q

blue vs purple

A

blue valves are used with ventilation

purple is used for spontaneous breathing off the ventilator

38
Q

Ostomy vs stoma

A

ostomy is the incision created for the trach tube. Stoma is just the hole without the tube in it.

39
Q

How long until a trach is being considered?

A

10-14 days

40
Q

Glottic edema

A

Swelling of the airway due to cuff pressure*

41
Q

How is a TE fistula typically diagnosed?

A

Consistent aspiration

42
Q

How often is trach care performed?

A

Q 8 hours and prn***

43
Q

What type of trach is common in pediatrics?

A

single cannula trachs**

They dont have an inner cannula and usually no cuff

44
Q

Main benefit of Hi Lo trachs**

A

Prevents aspiration and VAP via continuous suction as well as being able to inflate cuff MORE than 20-30 (it can go up to 40)

45
Q

***In order to use a fenestrated trach on the ventilator, what two things need to be done?

A

Inner cannula needs to be in place as well as DEFLATING the cuff

46
Q

**A Lanz trach tube will always do what?

A

keep cuff pressure at 34cmH2O maximum.

**Put 40ml of air into pilot balloon

47
Q

**What pressure does the foam cuff inflate to?

A

Always automatically inflates to 1 atm of pressure

48
Q

**3 ways to decannulate

A

Progressively smaller trach tubes, fenestrated trach, or trach buttons

49
Q

What pt is indicated for a trach button/plug?

A

anyone that needs to keep a patent stoma. Neuro patients use them frequently

50
Q

What are the criteria for someone to be a candidate for weaning?

A
  1. ability to cough 2. no infection 3 patent airway 4 secretion clearance 5 Passes a swallow test.
51
Q

**What do you do if you place an LMA and arent getting ventilation?

A

REPOSITION it, it likely just folded the glottis over the wrong way

52
Q

Which specialty airway is used for a spinal injury?

A

LMA

53
Q

What two areas does the King Airway seal?**

A

Esophagus and oropharynx

54
Q

Where should the king airway usually be placed?**

A

into the esophagus

55
Q

Main difference between combitube and king airway

A

can go into the trachea or esophagus.

56
Q

If the combitube goes where is usually does (the esophagus) which tube do you bag

A

Bag the blue one….if it is placed in trachea you would bag through the shorter port
