concentrator questions
 

Does anybody have any knowledge why I can not get a Devilbliss oxygen concentrator to produce oxygen, it only produces a red light and a buzzing sound?

Mike,
It can be that a piece has come loose on the side of the machine. Open it up and check your wires and make sure they are all connected. You could try hitting the reset button first but normally it's a connection that's just come loose!
Good luck

It also could be that the valve (where you connect your hose to the oxycon) is busted and restricting the flow - that's what happened to a friend of mine. Just need to replace the $20 part.
