Operation
Gas delivery
Zeus IE can be operated in the manual fresh-gas
delivery mode (FG ctrl. control mode) and in the

In contrast to conventional fresh-gas delivery, the
automatic control of oxygen, carrier gas and anes-
thetic agent takes place in a closed control loop.
Nitrous oxide-free system
A nitrous oxide-free device system can be config-
ured under Basic settings > More settings >

Throughout the system in nitrous oxide-free opera-
tion, N
2O monitoring and N2O setting elements are
turned off.
Adjusting mixed gas
1 Touch the MixGas standby button (A).
The MixGas settings dialog window containing the
control modes opens.

WARNING
If face masks are used, the end expiratory an-
esthetic agent measurement may be incorrect
on account of the leak to be expected. Do not
operate the device in the Auto ctrl. control
mode.

agents have to be avoided for medical rea-
sons, e.g., malignant hyperthermia:
