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.

cannula

A hollow surgical tube, into which is inserted a close fitting, sharp-pointed inner stiffener called a trocar. The combination can easily be pushed through the skin or the lining of a blood vessel or other tissue. When in position, the trocar is pulled backwards out of the cannula, leaving the latter in place. Fluids or other materials may then be passed.
