The Portable Hyperbaric Chamber Revitalair® 430+ is a hyperbaric semi-rigid chamber for low pressures (operating at pressures of no greater than 1.5 atmospheres absolute (ATA)). The operational design pressure of a hyperbaric chamber that encloses a human within its pressure boundary falls within the scope of the American Society of Mechanical Engineers Pressure Vessels Human Occupancy 1 (ASME PVHO 1-2012).
A mains electricity (AC-powered) hard-shelled vessel (e.g., metal, acrylic) in which a patient is placed to receive hyperbaric oxygen therapy (HBOT), the medical use of oxygen (O2) at a higher than atmospheric pressure. The device increases environmental O2 pressure above normal to promote movement of O2 into a patient's tissues. It typically includes an airlock(s) for patient/object entry, view ports, air valves, and a control panel. It is used to treat disorders that typically include decompression sickness, carbon monoxide poisoning, air/gas embolism, necrotizing tissue infections, and various injuries/wounds; it can also be used to study effects of pressure and decompression.
