18.11 Gas blender function
The Air / Oxygen Blender provides a Gas blend with adjustable proportions of Oxygen and Air.
Gas from the central gas supply enters the device through the gas input connections.
Blending of the gases occurs through two proportional valves.
The proportional valves, which also act as return valves, prevent the return flow of a gas into the
supply line of the other gas.An Oxygen sensor measures the Inspiratory Oxygen Concentration.
