7.3.1 Preset and activate AFGO in Standby
• Select 'Additional Fresh Gas Outlet (AFGO)'
and confirm selection in the dialog
• Set the AFGO ventilation parameters by
selecting each parameter and adjusting
them to the desired value using the rotary
knob
• Adjust the external circuit pressure relief
valve to an appropriate value.
• Turn the MAN/AUTO ventilation switch to
MAN
• To activate AFGO when preset, press 'Start
case' membrane button
• Verify there is flow at the Y-piece of the
external breathing circuit connected to the
AFGO outlet
Note that gas metrics and RR are displayed
when AFGO is active.
Ensure that surplus gas is evacuated by the
hospital’s gas evacuation system.
Depending on the type of external system and
current fresh gas settings, expired gas may
be diluted with fresh gas, causing the
measured gas metrics displayed on the control
panel to be lower than their actual values.
Ensure that the fresh gas flow is sufficient to
avoid unwanted CO

rebreathing.
7.3.2 Activate AUTO from AFGO
Parameters for Automatic Ventilation can be
preset during AFGO via the ventilation dialog
window.
• Turn the MAN/AUTO ventilation switch to
AUTO.
• Switch breathing circuits at the y-piece from
the external breathing system to the circle
system. Make sure that the sampling line is
still connected.
The fresh gas flow is automatically temporarily
increased to fill the circle system with the
correct gas mix. This procedure lasts for a few
seconds, during which time a dialog is visible.
Fresh gas mix is delivered according to the
preset parameters for the selected automatic
ventilation mode.
Waveforms and metrics according to selected
automatic ventilation mode are displayed.
Clinical alarms are pre-muted for a duration
of 30 seconds after the activation of Auto
mode, indicated by the pre-mute symbol and
count-down timer on the control panel screen.
Check and adjust relevant settings and alarms.
WARNING! Check upper pressure limit.
