According to a research report led by Professor Shay Efrati of Tel Aviv University in Israel, 35 64-year-olds inhaled oxygen for more than 60 times in a row under 2 atmospheres, and their average aging was reversed by 25 years. Most civilian and home hyperbaric oxygen chambers have a pressure of only 1.3-1.5kpa, so the international authoritative organization, the Undersea and Hyperbaric Medical Association, pointed out that oxygen chambers below 1.5 atmospheres cannot be proven to be useful. The home micro-enriched hyperbaric oxygen chamber developed by our company's R&D team is at 1.95 atmospheres, which is currently the closest value to the research report of Professor Shay Efrati of Tel Aviv University in Israel.
