Nasal oxygen Cannula

It’s a thin, flexible tube that goes around your head and into your nose. There are two prongs that go inside your nostrils that deliver the oxygen. The tube is attached to an oxygen source like a tank or container.There are high-flow nasal cannulas (HFNC) and low-flow nasal cannulas (LFNC). The difference between them is in the amount and type of oxygen they deliver per minute.
