ABSTRACT:
A life support system providing breathable gas from a high pressure source utilizes an exhaled gas treatment device to eliminate harmful components from exhaled gas and incorporates a novel rebreathable gas mixing and supply device in which inhalation pressure of the user activates a fresh breathable gas supply valve which, in turn, jets the fresh breathable gas into and through a mixing chamber, providing a booster type suction force to pull exhaled gas through the treatment device, mixing the treated, purified gas with the fresh gas and supplying the resultant mixture to the user.
