Gravity is a single-user hyperbaric oxygen chamber designed to bridge the gap between large, facility-based systems and lower-pressure personal chambers used primarily for wellness. The chamber is pressurized with air, while 100% medical-grade oxygen is delivered directly to the user through an independent breathing circuit. This separation limits oxygen accumulation inside the chamber while enabling operation at pressures up to 3.0 ATA. The pressure vessel is proof-tested at 7 ATA. A large front viewing window reduces the sense of enclosure and allows continuous observation by an operator during treatment. Automated pressure control and decompression reduce manual coordination, helping operators deliver consistent supervised sessions. Built on the same clinical engineering InterOcean has applied for 33 years to recompression chambers used to treat divers with decompression sickness, Gravity is a premium, professional-grade HBOT platform, not a mild hyperbaric wellness system, designed for single-user rehabilitation, sports recovery, wellness, and other professionally managed applications.
