A gas delivery system 1 for generating and supplying hypoxic gas 8 and hyperoxic gas 9 to a user has a fluid flow controller 5 controlling the flow of ambient air from a compressor 3 to a gas separator 6, for example using pressure swing adsorption, and for controlling the supply of hyperoxic gas 9 from the separator 6 to a storage vessel 12 and the supply of hypoxic gas 8 to an outlet port 7 to a user or back to the fluid flow controller 5 and on to a concentration controller 13 that diverts a proportion of the hypoxic gas 8 and recirculates it back through the gas separator 6 - allowing the user to control the concentration of oxygen within the hypoxic gas and provide a supply of hypoxic gas with variable oxygen content to the user as well as a supply of hyperoxic gas. |
