9.2 Circuit Description

When a gas source (medical oxygen) is supplied to the e500 ventilator via the
gas input connection, the gas will flow into the Flow control valve which is
used to control both the flow and rate of ventilation. The output of this valve is
connected to a selector switch which is used to direct the flow path either
directly to the ventilator output (if 100% oxygen ventilation is required) or
through a Venturi system used to entrain air to provide an oxygen
concentration of 60%.
