Amazing, with all due respect a class in logic might help. If systems designed and tested for aviation can fail then what are the chances of a medical system not designed nor tested for aviation could fail. I wrote of the kinked hose, and took steps to not have that happen again, plus I now fly with EDS. I did not have a logic jump that thought "gee this system was designed for aviation and failed, so why don't I make a system out of the cheapest parts I can. If you are oxygen depraved you will not be checking a flow meter, nor understand what it is telling you. Did you notice how no thinks this is a good idea?

Sounds like a candidate for the darwin award, and the absolute fixed thinker award. I remember seeing a news clip about an idiot that was trying to fill a gas tank at night from a can, couldn't see so they lit a match.

A lot of people are flying with systems designed for aviation but made 20, 40, even 60 years ago. And besides mechanical failures, other things can go wrong - see some anecdotes posted above and below, such as kinks in hoses, hoses pulled off of a fitting, etc. No matter how official and expensive a system is, I would use a flow meter to verify the flow (and still need to check that hose still reaches the mask etc). An exception is an EDS system, for which a flow meter is useless. But at least you can feel the puffs of gas in your nose (if using a cannula), and the EDS at least has built-in alarms for some sorts of faults.
