In medicine, a nasopharyngeal airway (NPA), nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open 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.

2024年1月30日 · A nasopharyngeal airway (NPA) device or "nasal trumpet" is a hollow plastic or soft rubber tube that can improve oxygenation and ventilation in cases where bag-valve-mask ventilation is ineffective. NPAs are inserted into the nose and through the posterior pharynx, clearing the airway by displacing the posterior tongue and soft palate.

2022年8月29日 · Nasopharyngeal airways are typically used to bypass obstructions in the mouth, nose, nasopharynx or base of the tongue. They are typically better tolerated (and less likely to trigger the gag reflex ) in patients who are partly or fully conscious compared to …

The Nasopharyngeal Airway (NPA) is a medical tube that is inserted through the nose and into the nasopharynx, which is the upper part of the throat. It is used to help with breathing and is typically directed downwards towards the lungs. Inserting the NPA along the lower pathway in the nose is safer because the upper pathway, which runs above ...

2024年10月17日 · A nasopharyngeal airway (NPA) is a flexible tube designed to maintain an open airway by passing through the nose and extending into the nasopharynx. It is commonly used in medical emergencies and situations where patients have difficulty maintaining a patent airway on their own.

Nasopharyngeal airway (NPA) or nasal trumpet; USE. Can provide an airway in patients with an intact gag reflex, trismus or oral trauma; Facilitate suctioning in patients with a weak cough; DESCRIPTION. Soft, flexible anatomically designed airway adjunct; Sized by measuring from the tip of the patient’s nose to the earlobe

A nasopharyngeal airway (NPA) is a thin, clear, flexible tube that is inserted into a patient’s nostril. The purpose of the NPA is to bypass upper airway obstruction at the level of the nose, nasopharynx or base of the tongue.

How to use a nasopharyngeal airway (NPA) What is an NPA? A flexible rubber tube which goes through the nose ends at base of tongue (an adjunct to help keep airway open) An oxygen mask or bag mask ventilation can be applied over the top if needed; Use: prevents tongue covering epiglottis in patients with reduced GCS.

2024年1月30日 · Proper airway management begins by determining the best airway approach for the patient. Factors that can influence airway choice include obesity, macroglossia, evidence of trauma, cervical collar use, presence of a gag reflex, and age.
