Nasal Cannula

Description

Nasal cannulas and face masks are used to deliver oxygen to people who don’t otherwise get enough of it. They are commonly used to provide relief to people with respiratory disorders.

A nasal cannula consists of a flexible tube that is placed under the nose. The tube includes two prongs that go inside the nostrils.

A face mask covers the nose and mouth.

Both methods of delivery attach to oxygen sources, which come in a variety of sizes.

Nasal cannulas and simple face masks are usually used to deliver low levels of oxygen to the patient. Another type of mask called the Venturi mask delivers oxygen at higher levels. Sometimes, nasal cannulas also can be used to deliver high levels of oxygen.
