A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. The apparatus can also include additional pressure regulation control systems. The gas mixture apparatus can be used to introduce and automatically perform the steps to achieve a desired concentration of the one or more gases contained in the pressurized chamber. The gas mixture apparatus can include the pressurized chamber within the apparatus itself such that no external devices are necessary for introducing the one or more gases into the mixing chamber.

1. A hand-held gaseous injector apparatus, comprising: a syringe body with an outlet;a plunger slidably disposed in the syringe body and with the syringe body, defining a first chamber within the syringe body;a metering device, at least partially within the syringe body, configured to control a volume of at least the first chamber when a first fluid is introduced into the first chamber, wherein the metering device comprises a plurality of protrusions disposed inwardly from an inner wall of the metering device and a moveable selector with a protrusion that can be moved between positions in alignment with the plurality of protrusions disposed inwardly from the inner wall of the metering device, wherein each of the plurality of protrusions comprises a surface configured to contact the protrusion of the moveable selector to limit movement of the plunger to one of a plurality of different positions, each different position corresponding to a different volume of the first chamber; anda filling mechanism configured to direct the first fluid into the first chamber of the syringe body so as to move the plunger and expand the first chamber. 2. The hand-held gaseous injector apparatus of claim 1, further comprising a second chamber, the second chamber comprising an internal volume containing at least a first gas in a concentration different than that in atmospheric air and at a pressure greater than that of the surrounding atmospheric air. 3. The hand-held gaseous injector apparatus of claim 2, wherein the second chamber is external to the hand-held gaseous injector apparatus. 4. The hand-held gaseous injector apparatus of claim 2, wherein the second chamber is a storage member, the storage member comprising an opening at a first end and an internal valve mechanism located adjacent the first end, the internal valve mechanism configured to seal the opening. 5. The hand-held gaseous injector apparatus of claim 4, wherein the internal valve mechanism comprises a piston, a seal, and a biasing member, the internal valve mechanism configured to seal the opening at least prior to activation of the system. 6. The hand-held gaseous injector apparatus of claim 5, wherein the internal valve mechanism does not seal the opening during phases of operation when an activation system is in an “open” position. 7. The hand-held gaseous injector apparatus of claim 4, wherein the storage member comprises a membrane over the first end so as to seal the opening. 8. The hand-held gaseous injector apparatus of claim 4, wherein the storage member comprises a relief valve configured to release the first gas when pressure within the storage member exceeds a preconfigured value. 9. The hand-held gaseous injector apparatus of claim 1, further comprising a release mechanism, wherein the release mechanism comprises a pin. 10. The hand-held gaseous injector apparatus of claim 9, wherein the release mechanism comprises a porous material, the porous material configured to at least partially filter the first gas. 11. The hand-held gaseous injector apparatus of claim 1, further comprising an activation system configured to commence and control operation of the apparatus. 12. The hand-held gaseous injector apparatus of claim 11, the activation system comprising an activation switch and an interlock mechanism configured to restrict movement of the activation switch such that the activation switch is hindered from moving in an improper order. 13. The hand-held gaseous injector apparatus of claim 12, wherein the interlock mechanism, when the activation switch is in a first position, hinders movement towards a third position. 14. The hand-held gaseous injector apparatus of claim 12, wherein the interlock mechanism, when the activation switch is moved from a first position to a second position, does not hinder movement towards a third position. 15. The hand-held gaseous injector apparatus of claim 12, wherein the activation switch, when in a third position, is received within a recess of a handle of the plunger. 16. The hand-held gaseous injector apparatus of claim 15, wherein the activation switch is flush or placed entirely within the recess of the handle. 17. The hand-held gaseous injector apparatus of claim 1, further comprising an activation system. 18. The hand-held gaseous injector apparatus of claim 17, wherein the activation system comprises an activation switch, an actuator body, and a biasing member, the biasing member configured to exert a force on at least one of an actuator body and a housing member. 19. The hand-held gaseous injector apparatus of claim 4, further comprising a housing configured to receive the storage member. 20. The hand-held gaseous injector apparatus of claim 19, the housing comprising two portions, wherein the two portions are configured to translate towards each other to activate the release of gas from the storage member. 21. The hand-held gaseous injector apparatus of claim 1, wherein the protrusion of the moveable selector comprises a latch. 22. A hand-held gaseous injector apparatus, comprising: a syringe body with an outlet;a plunger slidably disposed in the syringe body and with the syringe body, defining a first chamber within the syringe body;a metering device at least partially within the syringe body, the metering device being configured to limit the volume of at least the first chamber when a first fluid is introduced into the first chamber, wherein the metering device comprises a latch that can be moved between a plurality of positions in which the latch is aligned with a plurality of different protrusions, respectively, wherein the plurality of different protrusions are disposed inwardly from an inner wall of the metering device, wherein each of the plurality of different protrusions comprises a surface configured to define a point of contact with the latch to limit movement of the plunger to one of a plurality of different discrete positions, each discrete position corresponding to a different limit of the volume of the first chamber. 23. The hand-held gaseous injector apparatus according to claim 22, wherein the outlet of the syringe body comprises a nozzle and a valve disposed in the nozzle.
