  • Method And Apparatus For Inducing And Controlling Hypoxia
    Publication number: 20090173348
    Abstract: 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.

  • Method of maintaining constant arterial PCOand measurement of anatomic and alveolar dead space
    Patent number: 7100606
    Abstract: 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.
