Abstract:
1. An apparatus comprising: a hyperbaric chamber; a set pressure selection valve having an inlet operable to be coupled to a gas supply; a control system including a volume booster adapted to provide both oxygen to pressurize the hyperbaric chamber and controlled exhaust of the hyperbaric chamber, the volume booster having an inlet port operable to be coupled to a pressurized gas supply, an outlet port coupled to the hyperbaric chamber, and a reference port coupled to an outlet port of a set pressure selection valve; and a duplex analog pressure gauge having a first needle circuit coupled to the hyperbaric chamber and a second needle circuit coupled to the outlet port of the set pressure selection valve, wherein the control system is adapted to provide the controlled exhaust of the hyperbaric chamber concurrently with the set pressure selection valve maintaining a pressure of the hyperbaric chamber.
