Nasal cannula
Nasal Cannula
A Nasal Cannula (pronounced: /ˈneɪzəl ˈkænjʊlə/) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils and from which a mixture of air and oxygen flows.
Etymology
The term "Nasal Cannula" is derived from the Latin nasus meaning "nose" and the Latin canna meaning "reed", referring to the tube-like structure of the device.
Usage
The Nasal Cannula is primarily used to deliver supplemental oxygen to a patient or person who has a need for respiratory help. It is often used in a hospital setting but can also be used at home with a home oxygen concentrator or with portable oxygen.
