cannula

 [kan´u-lah]
a tube for insertion into a vessel, duct, or cavity. During insertion its lumen is usually occupied by a trocar; following placement, the trocar is removed and the cannula remains patent as a channel for the flow of fluids.
nasal cannula one that fits into the nostrils for delivery of oxygen therapy. Called also nasal prongs.

Critical care An O2 delivery device loosely attached to the head with 2 prongs inserted in the nose; the FiO2 delivered by an NC is 24–35%

NASAL CANNULA FOR OXYGEN DELIVERY.

nasal cannula

Tubing used to deliver oxygen at levels from 1 to 6 L/min. The nasal prongs of the cannula extend approx. 1 cm into each naris and are connected to a common tube, which is then connected to the oxygen source. It is used to treat conditions in which a slightly enriched oxygen content is needed, such as emphysema. The exact percentage of oxygen delivered to the patient varies with respiratory rate and other factors.
