1.2.1.1 Overview
The following table gives an overview of the integrated safety functions which come into
effect if problems occur during operation:
Fault
Leakage
Mains power supply
failure
Mains power supply
failure and battery dis-
charged
Failure of the central
gas supply system
Complete failure of
the gas supply
Flow measurement
failure
Failure of fresh-gas
delivery (electroni-
cally controlled mixer
only)
Ventilator failure
Screen fault (screen
does not respond to
operation or has
failed)

Safety function
Pressure regulation and PEEP compensation
– In mechanical ventilation modes, the set PEEP is actively
adjusted even in the case of small leaks.
– In pressure-controlled modes, the pressure is controlled
during the entire respiratory cycle.
Uninterruptible power supply provided by internal battery
– Device runtime in battery operation see Instruction for Use
– Automatic deactivation of the breathing system warmer to
increase battery runtime
– Manual ventilation and spontaneous breathing are available
– Emergency O delivery (electronically controlled gas mixer)
2
– Fresh-gas delivery (mechanically controlled gas mixer)
– Delivery of anesthetic agents via connected vaporizers
– Use of the connected gas cylinders
– Mechanical ventilation with ambient air possible (the hose
with the breathing bag will have to be removed for this)
– No anesthetic agent delivery from the connected vaporizers
possible; switch to intravenous anesthetic agent required
– Mechanical ventilation can be continued.
– Restrictions with regard to displayed measured values, mea-
surement accuracies, and when triggering mandatory
breaths are possible.
– Emergency O delivery
2
see Instruction for Use
– Anesthetic agent delivery from connected vaporizers possi-
ble
– All ventilation modes are available.
Alternatively:
– Backup manual mode
– Manual ventilation or spontaneous breathing possible
– Fresh-gas delivery available
– Anesthetic agent delivery from connected vaporizers possi-
ble
Alternatively:
– Backup manual mode
If backup manual mode is activated:
– Manual ventilation or spontaneous breathing possible
– Emergency O delivery (electronically controlled gas mixer)
