BV Compressing air is not an oxygen creator. Truth is scuba divers
know this very well Air is a mixture. This machine is only helping your
diaphragm.to get "AIR" not pure oxygen into your lungs. If your blood is
not getting enough oxygen out of the air than you need bottled pure
oxygen. These bottles are filled in a lab. This Rube Goldberg machine
can't "concentrate" it (as you claim) It is a piece of crap. Need more
oxygen in your blood buy it by the bottle. Do not smoke when using it.
The bottle will have on its label WARNING high pressure oxidizing
gas,vigorously accelerates combustion. Get the picture BV??? Bert
