The present invention pertains to a system, method, and device for treating sleep disorders. The present invention is particularly useful in the delivery of carbon dioxide (CO2) to a subject and in the treatment of sleep apnea. Furthermore, integration of components with various sensors and apparatuses associated therewith and attached thereto preferably complete a rebreathing circuit in the present invention. In various embodiments of the present invention where the above components are integrated as a rebreathing circuit, a subject is both the source and recipient of a controlled concentration of carbon dioxide. In such embodiments, treatment of sleep disorders becomes much more efficient and effective.

1. A sleep-related breathing disorder treatment system comprising: a capture device for capturing exhaled air from a subject;a positive airway pressure (PAP) device with at least one gas inlet port and a gas outlet port, the at least one gas inlet port for receiving the capture exhaled air from the subject, and the PAP device for mixing and pressurizing the captured exhaled air and a dilutive gas to a pressure that is greater than atmospheric pressure; anda delivery device connected to the gas outlet port for delivering the pressurized mixture of at least the captured exhaled air and dilutive gas from the PAP device to the subject, wherein the delivery device completes a rebreathing circuit from the capture device through the PAP device to the subject. 2. The system of claim 1, wherein the system is adapted so the gas delivered to the subject using the PAP device has a concentration of between 0.01 and 5.0 percent CO2, and the accuracy of the concentration of the CO2 delivered to the subject is within 10 percent of a desired concentration. 3. The system of claim 2, comprising at least two regulatory valves at both a proximal and a distal end of the capture device. 4. The system of claim 1, wherein the delivery device and the capture device comprise in part separate chambers of a multi-lumened hose with the delivery device chamber connected to the gas outlet port and the capture device chamber connected to the gas inlet port. 5. The system of claim 1, the delivery device further comprising a mask and a hose, the mask further comprising two regulatory valves, one for connecting to the hose and receiving the mixed gas from the PAP through the hose, and the other adapted for passing exhaled air into the capture device. 6. The system of claim 1, the system further comprising, a processor and the capture device further comprising a CO2 sensor with a signal for measuring the CO2 concentration of exhaled air within the capture device and a regulatory valve adjusted by the processor based in part on the signal from the CO2 sensor. 7. A method for treating sleep-related breathing disorders comprising the steps of: capturing exhaled air from a subject;providing the captured exhaled air from the subject to a positive airway pressure (PAP) device;mixing the captured exhaled air and a dilutive gas in controlled quantities; andproviding the mixture of at least captured exhaled air and dilutive gas to the subject using the PAP device to complete a rebreathing circuit. 8. The method of claim 7, wherein the mixed gas delivered to the subject using the PAP device has a concentration of between 0.01 and 5.0 percent CO2, and the accuracy of the concentration of the CO2 delivered to the subject is within 10 percent of a desired concentration. 9. The method of claim 8, further including the steps of measuring the captured exhaled air is with a CO2 sensor having a signal for measuring the CO2 concentration of exhaled air and regulating the exhaled air provided to the PAP device is with a processor based in part on the signal from the CO2 sensor. 10. The method of claim 9, wherein the mixed gas is provided to the subject with a mask and a hose, the mask further comprising two regulatory valves, one for connecting to the hose and receiving the mixed gas from the PAP through the hose, and the other adapted for passing exhaled air hack to the PAP device. 11. The method of claim 7, wherein the during the step of capturing exhaled air from a subject a CO2 sensor with a signal further measures the CO2 concentration of exhaled air and the exhaled air provided to the PAP device is regulated with a processor and a valve based in part on the signal from the CO2 sensor. 12. The method of claim 7, wherein the step of mixing is performed in part using baffles in the PAP device. 13. A positive airway pressure (PAP) device comprising: a mixing chamber further comprising a number of baffles for mixing at least a subject's exhaled air and a dilutive gas in controlled quantities;a pressurized air generator;an input port for passing the subject's exhaled air into the mixing chamber; andan output port for passing of a mixture of at least the subject's exhaled air and a dilutive gas out of the PAP device using at least in part the source of pressurized air for delivery to a subject. 14. The device of claim 13 wherein the PAP device is adapted so the gas delivered to the subject has a concentration of between 0.01 and 5.0 percent CO2, and the accuracy of the concentration of the CO2 delivered to the subject is within 75 percent of a desired concentration. 15. The device of claim 14, further including a delivery device comprising a mask and a hose, the mask further comprising two regulatory valves, one for connecting to the hose and receiving the mixed gas from the output port through the hose, and the other adapted for passing exhaled air to the input port on the PAP device. 16. The device of claim 15, wherein the hose connected to the mask and to the outlet port on the PAP device is a multi-lumened hose with two chambers one chamber connected to the PAP device input port for delivering exhaled air to the PAP device from the mask and other chamber connected to the output port of the PAP device for delivering mixed gas to the mask. 17. The device of claim 14, wherein the accuracy of the concentration of the CO2 delivered to the subject is within 10 percent of a desired concentration. 18. The device of claim 13, further comprising a second input port and a source of medical grade gas for inputting into the mixing chamber of the PAP device. 19. The device of claim 13, further comprising a display for displaying the amount of carbon dioxide included in the mixture of at least the subject's exhaled air and atmospheric air.
