    摘要： A method to maintain isocapnia for a subject. A fresh gas is provided to the subject when the subject breathes at a rate less than or equal to the fresh gas flowing to the subject. The fresh gas flow equal to a baseline minute ventilation minus a dead space gas ventilation of the subject contains a physiological insignificant amount of CO2. An additional reserve gas is provided to the subject when the subject breathes at a rate more than the fresh gas flowing to the subject. The reserve gas has a partial pressure of carbon dioxide equal to an arterial partial pressure of carbon dioxide of the subject. A breathing circuit is applied to the method to maintain isocapnia for a subject. The breathing circuit has an exit port, a non-rebreathing valve, a source of fresh gas, a fresh gas reservoir and a reserve gas supply.

    摘要： A portable isocapnia circuit and an isocapnia method. A breathing port of the circuit allows a subject to inhale and exhale. Connected to the breathing port, a bifurcate conduit has a first conduit branch and a second conduit branch. The first conduit branch has an atmospheric air inlet, from which the atmospheric air is provided for inhalation, an inspiratory check valve to allow a one-way flow of the atmospheric air, and an atmospheric air aspirator. The second conduit branch has a one-way expiratory check valve and a expiratory gas reservoir. A one-way check valve is used to interconnect the first and second conduit branch, from which the expiratory gas stored in the expiratory gas reservoir flows to the first conduit branch to mix with the atmospheric air when the minute ventilation exceeds the atmospheric air.

    摘要： An apparatus for inducing hypoxia in a subject is provided. The apparatus includes a breathing port, an inspiratory reservoir, means for introducing oxygen into the apparatus, means for controlling the flow rate of entry of oxygen into the apparatus at a rate below the subject's metabolic requirements, an expiratory reservoir having a vent, Sequential Gas Delivery means, and means for removing CO2 from the circuit. The Sequential Gas Delivery means are for directing the gases such that upon expiration, the subject expires into the expiratory reservoir, and, upon inspiration, subject inspires first from the inspiratory reservoir, and, on any breath, once said inspiratory reservoir is depleted, gas for the balance of that inspiration is delivered from the expiratory reservoir
