Cannula Source?

[mfleming]

Where are you sourcing your standard plain cannula? The medical cannula are way cheaper than the aviation sources... is there really a difference?


For reference, I'm using a Mountain High EDS, so I'm not relying on the cannula for efficiency

Medical Supply House

I have used both the standard medical supply house $2 cannulas and an aviation conserving $40 cannula. They both seem to work fine. I haven't noticed a significant difference in oxygen consumption between the two. A google search should show one close to your location. With a finger oxygen meter i keep track and adjust flow rates accordingly

2 liters is 2 liters. i just checked e bay. 10 pack for $15.

I just get them from Amazon. I also bought the tank and regulator there. I have a couple of cheap Amazon/China pulse oximeters...they work fine, are reliable and accurate but they're inconvenient for continuous use so I bought a Wellue pulse oximeter, which fits on a finger like a ring and can be comfortably worn continuously

With EDS, they tell you to use specific a specific cannula type: "Do not use standard medical cannulas as you may not receive adequate oxygen flow or oxygen conserving optimization." I thought it messed with the triggering but haven't tested it for myself.

If that's not true I'll look into getting some medical ones at least for one-off passengers - the EDS ones are $11 so not terribly expensive.
