Nasopharyngeal airway
Nasopharyngeal Airway
The Nasopharyngeal Airway (pronounced: nay-zoh-fuh-RIN-jee-uhl AIR-way), often abbreviated as NPA, is a type of airway adjunct, a tube that is designed to be inserted into the nasal passageway to secure an open airway.
Etymology
The term "Nasopharyngeal" is derived from two words: "Naso", which is a prefix from the Latin nasus meaning nose, and "Pharyngeal", which comes from the Greek pharynx meaning throat.
Usage
The primary purpose of a Nasopharyngeal Airway is to ensure the free passage of air in and out of the body, which can be hindered due to various reasons such as unconsciousness, facial trauma, or severe nasal congestion. It is commonly used in the field of emergency medicine and is considered a basic tool in airway management.
