21
Q

If a dog weighs more than 20 kg, the tube length should

A

increase 1 mm for every 5 kgs

22
Q

If a tube is too long, it creates more

A

dead space

23
Q

The patient end of the tube should lie

A

between the thoracic inlet and the larynx

24
Q

The tube should extend from the tip of the nose to

A

the thoracic inlet

25
Q

You can use this to help ease the passing of the tube

A

lubrication

26
Q

6 Supplies to have ready for intubation

A
  1. Scope
  2. 3 tubes of varying size
  3. tie in
  4. 3x3 gauze
  5. air syringe
  6. lidocaine (for cats)
27
Q

Restrainer should hold behind these teeth and extend the head and neck forward

A

canines

28
Q

2 positions an animal can be in for intubation

A
  1. sternal

2. lateral

29
Q

Horses should be positioned during intubation

A

lateral, with extended heat, neck and back

30
Q

Must be assessed by the restrainer prior to intubation

A

jaw tone

31
Q

Window for successful intubation is

A

short

32
Q

You should tie the tube around the

A

maxilla, mandible, or behind the ears

33
Q

Animals will not do this with proper placement

A

vocalize

34
Q

ET tube is advanced too far, breath sounds will be absent on one side and cause possible cyanosis

A

One lung intubation

35
Q

If this occurs, you can see extreme respiratory distress

A

Bronchial intubation

36
Q

This knot technique works really well for tying the tube

A

lark’s head

37
Q

Prevents aspiration, waste gas, and problems maintaining depth at normal concentrations

A

Cuffing

38
Q

How much air should you inject into the cuff?

A

5ml

39
Q

While slowly inflating the cuff, you should compress this and listen for leakage around the cuff

A

reserve bag

40
Q

If you hear this noise, there is a leak around the cuff

A

hissing

41
Q

This can cause tracheal trauma or necrosis

A

Overinflation of the cuff

42
Q

This can cause inadequate depth, contamination of room with inhalant

A

Underinflation

43
Q

This can help treat laryngospasms in cats

A

lidocaine

44
Q

Most common complication of endotracheal intubation

A

placing the tube into the esophagus

45
Q

This reflex must return before trying to extubate

A

swallowing

46
Q

Brachycephalic breeds should be extubated when

A

they are fully conscious

47
Q

This tube type is made of PVC polyvinyl chloride
Transparent, stiffer, cuff needs manually deflated, and high volume/low pressure
Easy on the trachea

A

Vinyl

48
Q

This type of tube is orange-red and not transparent
More flexible and inexpensive but prone to kinking and collapsing
Tends to dry and crack because it absorbs disinfectants
Cuff automatically deflates with cap release
Low volume, high pressure

A

Red rubber

49
Q

More expensive tube but combines strength and pliability
Less irritating to tissues and cuff requires manual deflation
High volume/low pressure
Considered the best

A

Silicone

50
Q

Specialized rubber tubes that contain a coil of metal or nylon embedded into the rubber designed to resist kinking or collapse
Used in human medicine

A

Spiral or anode

51
Q

Performed in emergency situations to establish an airway when endotracheal intubation is contraindicated or impossible

A

Tracheostomy

52
Q

A method of oxygen delivery

A

Ambu bag
