Wear a cannula so that it causes a minimum of discomfort. The nasal cannula is a small piece of plastic tubing that is attached to a larger tube which, in turn, connects to the oxygen container. The cannula has two small prongs that are inserted into the nostrils. If the prongs are curved, they should point downward inside the nostrils.
Oxygen is most commonly delivered to the patient via a nasal cannula or mask attached to the tubing.

Perforation of the nasal septum as a result of using a nasal cannula and non-humidified oxygen has been reported.
The nasal cannela was invented in the year 1949 by Wilfred jones. His employer patented it at that time and several different versions derive from the cannula contraption.
