So I want to try this oxygen rebreather mask trick prescribed by Paul Cheney.
I just don't know what to get and where. Is this a mask with a bag and a portable tank? Is there a type of oxygen tank I should get? Are there small portable ones?
Do I need a prescription to get this?
How much does the whole thing run?
