Troubleshooting
When the breathing bag is removed, the missing fresh-gas volume will
automatically be filled by ambient air. Nevertheless, the Fresh gas low or leakage
alarm is likely to be triggered.
12.3.4 After the central supply is restored
1. Connect the compressed gas hoses to the terminal units.
2. Close the gas cylinder valve on the corresponding gas cylinder again.
On devices that are equipped with Advanced Cylinder Support, the gas cylinder
valves can remain open.
12.4 Failure of fresh-gas delivery (electronically controlled
gas mixture)
If the fresh-gas delivery has failed, the emergency O2 delivery can be used to
deliver oxygen and anesthetic agent. The current ventilation mode and the fresh-
gas deficiency detection remain active.
In the event of a fault, illustrations and instructions showing how to start the
emergency O
2 delivery are displayed in areas (1) and (2).
The emergency O
2 delivery is started as follows:
WARNING
Risk of patient injury
If the gas mixer fails, no fresh gas is delivered.
► Check the vaporizer setting.
► Supply the patient with O
2.
► Use the emergency O2 delivery.
1. Set the O
2 switch upwards to the Add. O2 position. (Follow the illustration on the
screen.)
The Internal FG flow failure alarm will then be automatically downgraded.
2. Open the flow control valve on the O
2 flowmeter. Set the desired flow. This O2
flow flows through the vaporizer.
