A HYPOXIC SYSTEM AND METHOD FOR DELIVERING OXYGEN DEPLETED BREATHING GAS TO A SPACE

摘要

A hypoxic system 11 and method for delivering depleted oxygen breathing gas to a space 17. The system includes a low pressure blower unit 13 for generating air at very low pressure; and a low pressure membrane unit 15 having sufficient surface area to produce enough nitrogen for delivering hypoxic gas to the space with enough oxygen content to still function as a breathing gas. The very low pressure is in a range of 1 to 3 bar and is ideally 2 bar.
