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
