Abstract: Hyperbaric chamber control system and apparatus and related methods. A system for controlling, measuring, and reporting hyperbaric chamber sessions using the partial pressure of oxygen as the lead variable. Air is gently flushed from the bottom of the chamber, upwards, and a nostril-level oxygen pickup measures oxygen concentration in the chamber. Chamber pressure and oxygen concentration values are used to calculate the partial pressure of oxygen, and the session time is adjusted so that a subject treatment accurately reflects prescribed treatment.

Abstract: A system that includes an equipment package for separating nitrogen from air to produce enhanced oxygen air for use by divers. The package is combined with a pressure storage tank for air that is coupled to the package. A pressure storage tank is provided for enhanced oxygen air. A fill station including a high pressure gauge and a high pressure oxygen sensor is provided to fill divers' tanks. A compressor receives the enhanced oxygen air from the package and delivers high or low pressure enhanced oxygen air to the pressure storage tank via a pressure filter. Valving is provided for selectively controlling the flow in the system.

Abstract: A system for generating oxygen enriched air includes a compressed air supply for supplying compressed air and a permeable membrane gas separation system for separating a nitrogen gas component and an oxygen enriched air component from the compressed air. An oxygen analyzer is provided to detect an oxygen concentration in the oxygen enriched air component. The nitrogen gas component is divided, by a vortex tube, into a cold gas stream and a hot gas stream, and solenoid valves are actuated to modify a flow path of the compressed air through the cold gas stream and the hot gas stream in order to selectively heat and cool the compressed air. The oxygen enriched air is then selectively distributed for further use.
