Abstract: A personal breathing apparatus installed in an aircraft that is not fully pressurized, and configured to prevent or treat an adverse physiological event. The personal breathing system is configured so as to prevent, lessen or reverse hypercapnia by (i) facilitating removal of carbon dioxide generated the pilot by controlling pilot ventilation and/or (ii) limiting or decreasing the amount of carbon dioxide generated by the pilot by controlling the amount of oxygen breathed by the pilot.

Abstract: The present invention provides a system for training a subject to recognize the onset of hypoxia, the system including (i) a flight simulation system, and (ii) a hypoxia induction system, wherein the flight simulation system is operably linked to the hypoxia induction system. The system provides a tool for pilot training to a pilot, allowing for the delivery of standardized training programs where the tasks required for the operation of an aircraft are able to be coordinated with an induction of hypoxia in the subject. Such a system is also able to provide an assessment tool to demonstrate when a pilot has had sufficient training in recognizing the effects of hypoxia.

Abstract: An apparatus for the delivery of hypoxic air to a user comprising a biofeedback means where at least one physiologically measurable parameter of the user is substantially constantly measured by a monitoring means and the measured data transmitted to a control means, where the control means comprises: i) means for comparing the measured data of the at least one physiological parameter with a pre-set target value for the parameter; and ii) adjustment means to vary the oxygen concentration in the hypoxic air delivered to the user in response to the transmitted data.

Abstract: A hand-held rebreather/breathing apparatus for high altitude pre-acclimatization and training. Air exhaled by a user is directed to a reservoir bag for cooling and condensate collection. At inhalation negative pressure created a mixing chamber forces the air stored in the reservoir bag to pass via CO2 absorption chamber where it may be mixed with a fresh portion of the ambient air that influxes via orifice(s) communicating with this chamber. Baseline of the minimum oxygen concentration in inspired air can be pre-set by means of adjustment of the maximum volume of the reservoir bag and/or by means of altering of the number or diameter of one or a plurality of orifices for commination of the ambient air. Biofeedback may be provided by an oxygen monitor.
