A device for improving cognitive and functional capabilities by means of hypoxic and hyperoxic gas mixtures. An air splitter (5) separates oxygen and nitrogen and feeds these gases to a mixer (4), whose mixing rate is determined by feed back from a bio feedback regulator and an oximeter. The oximeter is connected to a finger piece sensor or pulse meter, and/or an ear-piece sensor for receiving inpute from a patient. The gas mixer feeds an adjusted oxygen and nitrogen mixture to the patient by way of a mouthpiece connected to the mixer.

Systems and methods for hypoxia delivery are provided. An apparatus for providing intermittent normoxia and hypoxia intervals includes a breathing component, a normoxia fluid source, a hypoxia fluid source, a valve, and a control system. The valve is configured to disrupt flow from at least one of the normoxia fluid source and the hypoxia fluid source and the control system is configured to cause the at least one valve to switch between delivery of fluid from the normoxia fluid source and the hypoxia fluid source while maintaining positive pressure at the breathing component.

The present invention includes a device for hypoxia training comprising: one or more electrochemical cells each comprising: a cathode and an anode separated by a proton exchange membrane, each of the anode and cathode in communication with an input and an output, wherein the input of the cathode is in fluid communication with ambient air, and wherein the input of the anode is in fluid communication with a source of liquid water; a power supply connected to the one or more electrochemical cells; and a mask in fluid communication with the output from the cathode of the one or more electrochemical cells, wherein oxygen is removed from the ambient air during contact with the cathode when hydrogen ions separated from liquid water by a catalyst on the anode convert oxygen in the ambient air into water.

Provided are a method for strengthening blood vessels with extreme ease and a compression and decompression control system used for performing the method. A compression and decompression control system 1 includes a band adapted to be placed around a particular part of a limb of a user and to apply a compression force to the particular part and a controller for controlling the compression force applied to the particular part with the band. The controller controls the compression force applied with the band in a manner that a compression operation applying a predetermined compression force to the particular part and a decompression operation completely removing the compression force applied to the particular part by the compression operation are alternately repeated. Repetition of the compression operation and the decompression operation allows the vascular endothelial cells of blood vessels of the user to generate a larger amount of nitric oxide, thereby strengthening the blood vessels.

An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen-depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen-enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.
