What is a patent nasal airway?
A nasopharyngeal airway is an effective way to maintain an open airway and allow for more effective ventilation if needed. A nasopharyngeal airway is a device that can be used for patients with or without a gag reflex.
How do you assess airway for patency?
PATENCY is assessed through the presence/absence of obstructive symptoms (stridor, secretions, snoring, etc.), or findings suggesting an airway that may become obstructed (singed nasal/facial hair, carbonaceous sputum, stab to neck with risk of expanding hematoma).
What can affect airway patency?
The relationships between upper airway geometry, negative intrapharyngeal pressure, activation of upper airway dilator muscles, and sleep state are important factors affecting the maintenance of upper airway patency.
When would you use a nasal airway?
Nasopharyngeal airways can be used in some settings where oropharyngeal airways cannot, eg, oral trauma or trismus (restriction of mouth opening including spasm of muscles of mastication). Nasopharyngeal airways may also help facilitate bag-valve-mask ventilation.
What does patent mean in medical terms?

A – Airway: is the airway patent? If the patient responds in a normal voice, then the airway is patent. Airway obstruction can be partial or complete. Signs of a partially obstructed airway include a changed voice, noisy breathing (eg, stridor), and an increased breathing effort.
What are the signs and symptoms of inadequate breathing?
Learning the signs of respiratory distress
- Breathing rate. An increase in the number of breaths per minute may mean that a person is having trouble breathing or not getting enough oxygen.
- Color changes.
- Grunting.
- Nose flaring.
- Retractions.
- Sweating.
- Wheezing.
- Body position.
When inserting a nasopharyngeal airway The EMT should remember that?
Deliver one breath every 5 to 6 seconds, with each ventilation lasting one second. When inserting a nasopharyngeal airway, the EMT should remember that the: nasal mucosa may bleed even with proper insertion. You are watching an EMT prepare the ambulance for the upcoming shift.
What patients can nasopharyngeal airway be used?
Nasopharyngeal airways are also used to keep the airway open and can be used with patients who are conscious or semi-conscious. For example, semi-conscious patients may need an NPA because they are at risk for airway obstruction but cannot have an OPA placed due to an intact gag reflex.
Does patent mean open or closed?
lying open; not enclosed or shut in: a patent field.
