Questions and Answers

What is the primary purpose of an oropharyngeal airway?

  • To facilitate tracheal intubation (correct)

    Study Notes

    Artificial Airways

    • Devices inserted orally or nasally to maintain airway patency
    • Do not affect cervical spine stability

    Oropharyngeal Airway (O-A)

    • Inserted through the mouth to the oropharynx
    • Used to maintain airway patency in decreased consciousness
    • Lifts tongue and epiglottis away from posterior pharyngeal wall
    • Prevents ET tube obstruction
    • Protects tongue during biting and seizures
    • Facilitates oropharyngeal suctioning
    • Risks: trauma during insertion, gag reflex induction, lack of aspiration protection, incorrect size may obstruct airway

    Nasopharyngeal Airway

    • Inserted through the nose to the nasopharynx
    • Bypasses the mouth
    • Alternative to O-A when mouth cannot be opened
    • Tolerated by semi-awake patients
    • Size estimation: 6 for average female, 7 for average male
    • Insertion: left-facing bevel eases right nostril insertion, distal end beyond soft palate but not epiglottis
    • Risks: airway obstruction if too large, epistaxis, trauma to nasal mucosa

    Nasopharyngeal Airway Contraindications

    • Bleeding disorders, anticoagulants, nasal deformities, sepsis
    • Excessive insertion force can create false passage or intracranial placement
    • Incorrect size can cause pressure necrosis or ineffectiveness

    Nasopharyngeal Airway Additional Considerations

    • Depress pharyngeal and laryngeal reflexes to prevent coughing and laryngospasm
    • Use appropriate size airway
    • Lubricate airway before insertion

    Nasopharyngeal Airway Potential Complications

    • Trauma to tongue, nose, uvula, pharynx, teeth
    • Long airways can induce laryngospasm
    • Latex allergy
    • Tissue edema
    • Ulceration and necrosis
    • Central nervous system (CNS) trauma in patients with basilar skull fractures
    • Retention, aspiration, or swallowing problems
