How to Use a Breathing Tube

tubes

A breathing tube or nasal cannula is a device used to deliver supplemental oxygen. It is a small piece of plastic tubing that is attached to a larger tube which, in turn, connects to the oxygen source. The cannula has two small prongs that are inserted into the nostrils. Oxygen flows from these prongs when the main tubing is directly connected to an oxygen generator or tank.

To wear a breathing tube comfortably:

  1. Insert the prongs into the nostrils. They are are usually most comfortable if they are pointing downward.
  2. Lift the tubes on either side of the nose and fit them over the ears. Then move the slider up under the chin to adjust for fit.
  3. Connect your tubing to your oxygen generator or tank.
