Local Control of the Electronic Gas Blender
Controlling the Gas Flow
The gas flow control knob has a graphic indicating the direction to turn the knob to
increase or decrease gas flow. Turn the knob counterclockwise to increase the gas
flow rate and clockwise to decrease the gas flow rate.
Note: When necessary, the gas flow control knob can be used to set the gas flow
rate > 10 L/min. The setpoint will be displayed at the top of the gas flow slide bar on
the Central Control Monitor as an approximate reading. The gas flow icon will read >
10. Monitor the patient status closely and use either the gas flow control knob or the
gas flow slide bar to adjust the flow rate as required.
Note:
The gas flow knob of the electronic gas system has hard stops at both ends
of its travel. Turn the gas flow knob clockwise until it reaches the hard stop to shut off
gas flow. Turn the gas flow knob counter-clockwise until it reaches the hard stop to
achieve maximum gas flow.
Note: When using the gas flow control knob of the electronic gas system to increase
gas flow from 0 L/min, the gas flow will increase slowly until one full counter-
clockwise revolution of the gas flow knob has been reached. Multiple turns of the gas
flow knob, as indicated by the label on the control panel, may be required to reach the
desired gas flow rate.
Use the external, mechanical flowmeter (supplied in the Accessory Kit) just before
the oxygenator to detect any possible gas leak between the gas outlet and the
oxygenator and as a backup to monitor gas flow in the event Central Control Monitor
display capability is lost.
