A method of providing a source of breathable humidified oxygen gas. A membrane oxygen humidifier is provided that includes at least one water permeable membrane and an enclosure. The at least one water permeable membrane has a first membrane side and a second membrane side that are in communication through the water permeable membrane. The enclosure extends over the second membrane side and wherein the enclosure has an air inlet port and an air outlet port. A first gas containing oxygen is directed past the first membrane side. The second gas is directed past the second membrane side with a fan. The first gas is humidified by transferring moisture through the at least one water permeable membrane from the second gas to the first gas.

1. A method of providing a source of breathable humidified oxygen gas, wherein the method comprises: providing a membrane oxygen humidifier comprising at least one water permeable membrane and an enclosure, wherein the at least one water permeable membrane has a first membrane side and a second membrane side that are in communication through the water permeable membrane, wherein the enclosure extends over the second membrane side and wherein the enclosure has an air inlet port and an air outlet port;directing a first gas containing oxygen past the first membrane side;directing the second gas past the second membrane side with a fan; andhumidifying the first gas by transferring moisture through the at least one water permeable membrane from the second gas to the first gas. 2. The method of claim 1, wherein the first gas has a first moisture concentration, wherein the second gas has a second moisture concentration and wherein the second moisture concentration is greater than the first moisture concentration. 3. The method of claim 2, wherein after humidification, the first gas has a third moisture concentration that is substantially equal to or less than the second moisture concentration. 4. The method of claim 2, and further comprising increasing the second moisture concentration with a supplemental humidification source that is positioned proximate the air inlet port. 5. The method of claim 1, and further comprising providing the first gas using an oxygen concentrator. 6. The method of claim 1, wherein the water permeable membrane comprises a hollow fiber membrane, a flat sheet membrane, a spiral wound membrane or combination thereof. 7. The method of claim 1, wherein the water permeable membrane has a selective membrane with a greater selectivity for water over both nitrogen and oxygen. 8. The method of claim 1, wherein the fan is positioned proximate at least one of the air inlet port and the air outlet port. 9. The method of claim 1, and further comprising: operably attaching an air inlet port cover to the enclosure, wherein the air inlet port cover is movable between an open position and a closed position and wherein the air inlet port cover substantially covers the air inlet port when in the closed position; andoperably attaching an air outlet cover to the enclosure, wherein the air outlet port cover is movable between an open position and a closed position and wherein the air outlet port cover substantially covers the air outlet port when in the close position. 10. The method of claim 8, and further comprising: biasing at least one of the air inlet port cover and the air outlet port cover to the closed position; andautomatically moving at least one of the air inlet port and the air outlet port from the closed position to the open position when the fan is activated. 11. The method of claim 1, and further comprising activating and deactivating the fan with a switch, wherein the switch is manually operable, operable based upon sensing flow of gas through the water permeable membrane or combination thereof. 12. A method of providing a source of breathable humidified oxygen gas comprising: providing a membrane oxygen humidifier comprising at least one water permeable membrane, an enclosure and a fan, wherein the at least one water permeable membrane has a first membrane side and a second membrane side that are in communication through the water permeable membrane, wherein the enclosure extends over the second membrane side, wherein the enclosure has an air inlet port and an air outlet port and wherein the fan is positioned proximate to at least one of the air inlet port and the air outlet port;directing a first gas containing oxygen past the first membrane side;directing a second gas past the second membrane side; andtransferring moisture through the at least one water permeable membrane from the second gas to the first gas. 13. The method of claim 12, wherein the first gas has a first moisture concentration, wherein the second gas has a second moisture concentration and wherein the second moisture concentration is greater than the first moisture concentration. 14. The method of claim 13, wherein after moisture transfer, the first gas has a third moisture concentration that is substantially equal to or less than the second moisture concentration. 15. The method of claim 13, and further comprising increasing the second moisture concentration with a supplemental humidification source that is positioned proximate the air inlet port. 16. The method of claim 12, and further comprising providing the first gas using an oxygen concentrator. 17. The method of claim 12, wherein the water permeable membrane comprises a hollow fiber membrane, a flat sheet membrane, a spiral wound membrane or combination thereof. 18. The method of claim 12, wherein the water permeable membrane has a selective membrane with a greater selectivity for water over both nitrogen and oxygen. 19. The method of claim 12, and further comprising: operably attaching an air inlet port cover to the enclosure, wherein the air inlet port cover is movable between an open position and a closed position and wherein the air inlet port cover substantially covers the air inlet port when in the closed position; andoperably attaching an air outlet cover to the enclosure, wherein the air outlet port cover is movable between an open position and a closed position and wherein the air outlet port cover substantially covers the air outlet port when in the close position. 20. The method of claim 19, and further comprising: biasing at least one of the air inlet port cover and the air outlet port cover to the closed position; andautomatically moving at least one of the air inlet port and the air outlet port from the closed position to the open position when the fan is activated. 21. A method of measuring oxygen concentration in a gas comprising: providing a membrane oxygen humidifier comprising at least one water permeable membrane, wherein the at least one water permeable membrane has a first membrane side and a second membrane side that are in communication through the water permeable membrane;increasing an oxygen concentration in a first gas by passing the first gas through an oxygen concentrator;directing a first gas past the first membrane side;preventing the second gas from flowing past the second membrane side; andmeasuring a concentration of oxygen in the first gas. 22. The method of claim 21 and further comprising: permitting the second gas to flow past the second membrane side; andtransferring moisture through the at least one water permeable membrane from the second gas to the first gas. 23. The method of claim 21, wherein the membrane oxygen humidifier further comprises an enclosure that extends over the second membrane side, wherein the enclosure has an air inlet port and an air outlet port and wherein preventing the second gas from flowing past the second membrane side comprises covering at least one of the air inlet port and the air outlet port. 24. The method of claim 23, and further comprising covering at least one of the air inlet port and the air outlet port with a cap. 25. The method of claim 24, and further comprising mechanically moving the cap between an open position and a closed position. 26. The method of claim 24, and further comprising biasing the cap in a closed position.
