Q

Name the flap that is attached to the entrance of the larynx and projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally.

A

Epiglottis

17
Q

into what is the tip of the curved laryngoscope blade placed?

A

The vallecula

18
Q

All anesthesia carts should contain at least which four blades?

A

MAC 3 & 4 and Miller 2 & 3

19
Q

When should the batteried on the laryngoscopes be changes?

A

When the light on the scope is not blinding

20
Q

Name this item

A

Endotracheal tube (ETT)

21
Q

What is a stylet?

A

A malleable metal or plastic stent over which an endotracheal tube is passed

22
Q

The stylet should be advanced within the endotracheal tube (ETT) until what?

A

Until the tip is just above the Murphy eye in the distal end of the tube

23
Q

After advancing a stylet into the endotracheal tube to just above the Murphy eye, what should you do at the circuit end of the tube

A

Bend the stylet so that it can advance no further

24
Q

Name and Purpose

A

Magill forcepts

To retrieve foreign bodies from the airway.

25
Q

What is the purpose of a Gum elastic catheters or bougies (GEB), also known as endotracheal tube introducers?

A

It is used to advance the endotracheal tube.

A small endotracheal tube is then advanced over the bougie into the glottis, the bougie is then withdrawn and correct placement of the endotracheal tube is confirmed.

26
Q

What are the four basic types of tape and what are their purposes?

A

Paper – IVs if patient is allergic to other tapes
Plastic – IVs; eyes; LMAs; nasal cannula
Silk – ETTs; NGs (nasogastric tube)
Pink – ETTs; LMAs; especially used in pediatrics; very sticky

27
Q

Name this item

A

Laryngeal mask airway

28
Q

What are the two reasons for using a tube tree (tube holder)?

A
  • Provides support to the anesthesia breathing circuit.
  • Reduces tension on the endotracheal tube
29
Q

Name the eight basic items you are required to have available to intubate a patient

A

an oxygen source
an oral or nasal airway
a face mask
a resuscitation bag
a reliable suction apparatus
a laryngoscope
an endotracheal tube
a stylet

30
Q

Name the six recommended adjunct items to set up in the OR

A

Magill forceps
Intubating catheters
ET tube tape
Eye tape
Tube tree (holder)
LMA

31
Q

Review the seven important rules to follow. (No need to memorize)

A
  • Learn to examine the airway quickly.
  • Know the various equipment options available for airway support and instrumentation.
  • Choose the correct piece of equipment for the job. Consider backup equipment and techniques.
  • Ensure oxygen and suction are always available.
  • Never leave the patient with an airway problem unattended.
  • Do not forget the basics in the case of equipment failure.
  • Get immediate help when doubt or unanticipated difficulty is encountered with a patient’s airway. Waste no time in preventing the irreversible sequelae of hypoxia!
