摘要：
In various embodiments, flow rate of fluids, such as oxygen, nitrous oxide, and air, may be electronically and/or mechanically controlled. An electronically controlled auxiliary common gas output (ACGO) valve may direct the gas mixture, including one or more gases and/or anesthetics, either to a primary breathing machine or to an ACGO of an anesthesia delivery machine. The ACGO valve may include a piloted shuttle valve comprising a valve body and a piston configured to translate within the valve body. The piston may divert the gas mixture to a primary breathing system outlet when translated to a first position and to an ACGO when translated to a second position. An electronically controlled drive gas may toggle the position of the piston. In some embodiments, the piloted shuttle valve may be spring loaded and default to directing the gas mixture to the primary breathing system.
