The gas blendercontrols the mixing to produce the mixed gas having a predetermined mixturesetpoint, generally an oxygen percentage, and a predetermined controlsetpoint, generally a pressure setpoint or flow rate setpoint. The gas blenderprovides an auxiliary mixed gas source for use by an auxiliary piece ofequipment such as a nebulizer or resuscitation bag. The gas blender includes aprimary gas inlet passageway, a secondary gas inlet passageway, a gas mixingapparatus, a mixed gas distribution passageway with an auxiliary mixed gasoutlet, a gas sensor, a delivery sensor, a mixed gas delivery control valve, amixed gas controlled passageway, and a controller.
