Methods of securing and maintaining the airway Flashcards
Define normal respiration
It is the involuntary, unimpeded passage of air from the atmosphere to the lungs where Oxygen is exchanged for carbon dioxide.

Describe an oropharyngeal airway device
- It is a rigid, kink resistant device that pushes the tongue forward and Kris the epiglottis off the posterior pharyngeal wall.
- It is latex free
- It does not prevent aspiration
- It has different sizes (color coded)
- It has a flange to limit the depth of insertion
- It has a reinforced bite block
- It has a tapered end which gets to reduce oropharyngeal mucosa trauma during insertion

1) Difficult intubation
2) Failed intubation
