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. illustrationillustration

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.
