How does a nasal cannula work?
A nasal cannula is a small, flexible tube that contains two open prongs intended to sit just inside your nostrils. The tubing attaches to an oxygen source and delivers a steady stream of medical-grade oxygen to your nose.

When is a nasal cannula used?
Using a nasal cannula means you'll have increased oxygen levels, and hopefully increased energy and reduced fatigue, as you'll be able to breathe easier during the day and sleep better at night.
