24
Q

What is the purpose of the larynx?

A

25
Q

Which laryngeal cartilages are unpaired?

A

  • Epiglottis
26
Q

Which laryngeal cartilages are paired?

A

  • Posterior: longitudinal trachealis muscle
  • Anterior: Tracheal rings (bougie intubation)
29
Q

Is airway history or assessment more valuable?

A
  • Airway history
30
Q

What portions of patient history can be a cause for airway concern? Which is most important?

A

What would be preferred?

A
  • Submandibular compliance (tip of chin to thyroid notch)
