The gas blender controls the mixingto produce the mixed gas having a predetermined mixture setpoint, generallyan oxygen percentage, and a predetermined control setpoint, generally a pressuresetpoint or flow rate setpoint. The gas blender provides an auxiliary mixed gassource for use by an auxiliary piece of equipment such as a nebulizer or resuscitationbag.
