We don’t have the benefit of marketing the EDS anywhere outside of the aviation market. The FDA, which treats any oxygen device as a medical device and oxygen for consumption as a drug, vigorously inhibits any such marketing unless it is registered as a medical device and strictly sold through pre-approved marketing and distribution methods. However, the FAA requires the use of oxygen in aviation, placing such equipment and AVO/ABO marked oxygen just barely outside the ospisios of the FDA. With the FDA on one side and the FAA on the other our market freedom is indeed severely restricted.
Much R&D, money and man-years of testing along with state-of-the-art micro-electronics and proprietary sensor technology went into the patented EDS system so that it could be the best oxygen delivery technology available to the aviator.
The R&D was a costly gamble, but became obviously worth it in the first year it was released (1993). Feedback shows that aviators all over the world and of all types appreciate and use the EDS every day.
