Oxygen concentrator apparatus and method of use are described herein. The oxygen concentration may include at least one canister; gas separation adsorbent disposed in at least one canister, and a compression system. The compression system may include at least one compressor coupled to the at least one canister. The compressor may include a first rotor comprising at least two projections and a second rotor comprising at least two recesses. During rotation of the first and second rotors, gas moves through the compressor to at least one of the canisters. In the canisters, gas separation adsorbent may separate at least some nitrogen from air produce oxygen enriched gas.

The apparatus of claim 1, wherein the first rotor and second rotor rotate in opposite directions during use. 3. The apparatus of claim 1, wherein a first projection of the at least two projections is diametrically opposed to a second projection of the at least two projections. 4. The apparatus of claim 1, wherein a first recess of the at least two recesses is diametrically opposed to a second recess of the at least two recesses. 5. The apparatus of claim 1, wherein at least one of the projections of the first rotor enters and exits at least one of the recesses of the second rotor during rotation of the rotors. 6. The apparatus of claim 1, wherein the first rotor is positioned adjacent to the second rotor such that passage of a substantial amount of gas between the first and second rotors is inhibited. 7. The apparatus of claim 1, further comprising a drive transmission system coupled to the first and second rotors, the drive transmission system configured to rotate the first and second rotors. 8. The apparatus of claim 1, wherein, during a complete revolution of the first rotor, at least one of the projections of the first rotor emerges from at least one of the recesses of the second rotor and enters a second recess of the second rotor such that fluid communication between an inlet passage of the compressor and an outlet passage of the compressor is inhibited. 9.

A method providing oxygen enriched gas to a user of an oxygen concentrator, the oxygen concentrator comprising: at least one canister; andgas separation adsorbent disposed in at least one canister,a compression system, the compression system comprising at least one compressor coupled to at least one canister, at least one compressor comprising: a first rotor comprising at least two projections;a second rotor comprising at least two recesses; anda drive transmission system coupled to the first and second rotors; the method comprising: applying power to the drive transmission system such that the drive transmission system rotates the first and second rotors in opposite directions, wherein rotation of the first and second rotors draws air into the compression system and discharges air to at least one canister; andseparating at least some nitrogen from air in the canister to produce oxygen enriched gas. 13. The method of claim 12, further comprising: automatically assessing a preselected prescription for the oxygen concentrator;automatically assessing the breathing rate of the user during use of the oxygen concentrator;operating the compressor at a percentage of the normal maximum drive transmission system speed, wherein the percentage is assessed based on the preselected prescription and the assessed breathing rate; andadjusting a speed of the drive transmission system to a different percentage of the normal maximum drive transmission system speed based on changes in the prescription and/or the breathing rate of the user. 14. The method of claim 13, wherein program instructions are operable to run the drive transmission system at a speed greater than the normal maximum drive transmission system speed when a breathing rate of the user exceeds a predetermined breathing rate and when the prescription is set at or above a predetermined rate. 15. The method of claim 12, further comprising operating the compression system to create a sufficient amount of the oxygen enriched gas to meet a prescription requirement of the user. 16. The method of claim 12, wherein providing the oxygen enriched gas to the user comprises providing one or more pulses of the oxygen enriched gas to the user. 17. The method of claim 16, further comprising operating the compression system to create a sufficient amount of the oxygen enriched gas to meet a prescription requirement of the user. 18. The method of claim 12, wherein the oxygen concentrator further comprises an accumulation chamber coupled to one or more of the canisters, wherein the method further comprises directing the oxygen enriched gas produced in one or more of the canisters into the accumulation chamber. 19. The method of claim 12, wherein the oxygen concentrator has a weight of less than about 5 lbs.
