Extra Nasal Cannula(s)

Good to have extras for more people to use, and you’ll want to trade them out occasionally as they get ‘snotty’. You can clean them for awhile using alcohol solution.
Note: Used cannula hoses are still useful (cut off the cannula) for bubbler, spot applicator and torch fuel-gas hoses.

Where to buy Cannulas

You can buy them lots of places online, like from Amazon, but less expensive from sources like this.
