Benefits of breathing o2
Ok an oxygen bar is a free-standing bar which people sit or stand at to breathe 95% pure oxygen and aromatherapy from a disposable nasal cannula, the air we breath normally is only about 21% o2 the rest is nitrogen and other stuff. These bars can service anywhere from 1 to 18 people simultaneously, and they are usually manned by one or two bartender/technicians.
The oxygen is not kept under pressure nor is it administered from a tank. If anyone offers this service they are breaking the law! (That would be considered "medical Oxygen." Our oxygen is produced by oxygen concentrators (generators) which take the ambient air that we breathe everyday and separates the nitrogen from this ambient air with a molecular filter. Most of the nitrogen is expelled during this cycle and the oxygen is concentrated and pushed out of the machine through a tube which is attached to the infusers which sit on top of the bar. It is there that the bartender/technician controls the flow of the oxygen to the individual bottles that hold water and the all-natural, essential, therapeutic grade aromas. In turn, the bottles bubble when turned on and oxygen is forced through the other opening of the bottle which has another open ended tube on it. It is there that the bar patrons connect the nasal cannulas while breathing normally.
