Gas flow

WARNING
Risk due to impermissible gas supply
pressure
Impermissible gas supply pressures may
cause incorrect gas composition.
Check the supply pressures of the central gas
supply and of the gas cylinders before
operation.
WARNING
Risk due to impermissible gas supply
Using oxygen supplies with less than 100 %
O may cause incorrect gas composition.
2
When using O , only use 100 % O

WARNING
Danger when using O
The following effects may occur:
– Discrepancies between the set value and
the actual value for fresh-gas flow and O
concentration in the fresh gas
– Inaccurate measured values for volume,
anesthetic agent consumption,
econometer (optional), and low-flow
wizard
– Inaccuracy in the FiO
– Inaccurate volume delivery in volume-
controlled ventilation modes
– Accumulation of argon in low-flow
operation and minimal-flow operation
Do not use any O concentrators.

Gas cylinders
1 Open the gas cylinder valves slowly.
Check that the displayed pressures are
sufficient.
When using pressure reducers without
electronic pressure measurement, read the
pressure from the pressure gauge.
2 Close the gas cylinder valves.
On devices that are equipped with Advanced
Cylinder Support, the gas cylinder valves can
remain open during operation. These devices are

identified by an appropriate label near the gas
inlets, see page 28.
