ABSTRACT:
Method for regulating hyperbaric chamber pressure at a prescribed level while a continuous supply of fresh gas flows into the hyperbaric chamber. Apparatus consists of a hermetically sealed pressure vessel plenum with a cavity that contains a gas regulating device. Sealed pressure piping means connects the gas regulating device intake to a hyperbaric chamber port. Sealed pressure piping means connects the gas regulating device vent though the plenum housing to the atmosphere. The plenum cavity has a port with a valve through which sealed piping means receives gas pressure from the hyperbaric chamber. Convenient management of hyperbaric chamber pressure at a determined pressure level can occur with closure of plenum valve during hyperbaric chamber pressurization. After closure of plenum valve any additional gas flow into hyperbaric chamber will vent through the gas regulating apparatus.
