Abstract
Method and apparatus varies the oxygen concentration level of air delivered to a person for treatment on training purposes. The apparatus includes a display device for displaying current physiological data as well as data from previous sessions for comparison purpose. The oxygen level is precisely controlled by a central processing unit in response to input data from the person.
Claims3
Apparatus for delivering a precise concentration of oxygen in air to a person comprising;
- a) an oxygen concentrator having an outlet for oxygen and an outlet for exhaust air;
- b) a mixing valve having an input for oxygen from the concentrator, an input for exhaust air from the concentrator, and an output for a mixture of exhaust air and oxygen from the concentrator,
- c) an air mask and air conduit connected to the mixing valve output,
- d) a flow meter and an oxygen concentration meter connected to the air conduit, and connected to a central processing unit,
- e) a plurality of physiological sensors connected to the central processing unit,
- f) a display device connected to the central processing unit,
- g) the central processing unit being programed to control the mixing valve in response to inputs from the flow meter, the oxygen concentration meter, and the plurality of physiological sensors.
