AUXILIARY GAS MIXING IN AN ANESTHESIA SYSTEM
First Claim
1. A system comprising:
- a main output configured to provide a first mixture of gases and an anesthetic agent to a patient;
an auxiliary output configured to provide a second mixture of gases to the patient, wherein the main output and the auxiliary output are configured to operate independently of each other;
an anesthesia machine configured to selectively mix oxygen from an oxygen source and one or more other gases so as to provide a first flow rate and a first oxygen percentage for the first mixture of gases, and to combine the anesthetic agent with the first mixture of gases; and
an auxiliary gas control subsystem configured to selectively mix oxygen from the oxygen source and one or more other gases so as to provide a second flow rate and a second oxygen percentage for the second mixture of gases provided through the auxiliary output.

Abstract
An anesthesia system includes a main output and an auxiliary output. The main output and the auxiliary output are configured to operate independently of each other. The main output may provide a first mixture of gases and an anesthetic agent to a patient. The auxiliary output may provide a second mixture of gases to the patient. A user may selectively mix oxygen and at least one other gas such that the second mixture of gases is provided to the auxiliary output at a desired flow rate and such that the second mixture of gases includes a desired oxygen percentage level. The second mixture of gases provided through the auxiliary output is prevented from flowing back into the anesthesia system to reduce or prevent contamination of the gases provided through the main output.

15. A method for selectively providing mixed gases to a patient through a first output and/or a second output of an anesthesia system, the method comprising:
-
forming a first gas mixture by selectively mixing a first gas from a first source with a second gas from a second source; combining the first gas mixture with an anesthetic agent; providing the first gas mixture and the anesthetic agent through the first output; and independent of mixing or providing the first gas mixture; forming a second gas mixture by selectively mixing the first gas from the first source with at least one of the second gas from the second gas source and a third gas from a third gas source; and providing the second gas mixture through the second output. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A system for selectively providing mixed gases to a patient through a first output and/or a second output of an anesthesia system, the system comprising:
-
means for forming a first gas mixture by selectively mixing a first gas from a first source with a second gas from a second source; means for combining the first gas mixture with an anesthetic agent; means for providing the first gas mixture and the anesthetic agent through the first output; and means, independent of the means for forming or means for providing the first gas mixture, for; forming a second gas mixture by selectively mixing the first gas from the first source with at least one of the second gas from the second gas source and a third gas from a third gas source; and providing the second gas mixture through the second output. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
