Q

What are 6 characteristics of intubation? What are 2 considerations?

A
  1. “Definitive” or formal airway ie
    1. Nasotracheal/Endotracheal
    2. Tracheostomy
  2. Tube to just above carina
  3. Inserted by medical staff/advanced paramedics (very hard to intubate)
  4. Only access to ventilation
  5. Often require sedation to tolerate it
  6. Condition must be reversible
    • If someone had terminal cancer –> could not be appropriate

This is the only airway (must make sure equipment is safe)

Considerations:

  • Unable to talk (think about QoL)
  • must be intensive care –> beds are scarce (need to know have good prognosis)
