Overview
3.2.12.3 Overview
The following table gives an overview of the integrated safety functions which come
into effect if problems occur during operation:
Fault
Safety function
Leakage
Automatic leakage compensation
– The pressure is held constant at the PEEP level.
– With pressure-controlled breaths, the pressure is regu-
lated according to the set pressure.
(In all pressure-controlled ventilation modes, small
amounts of leakage are compensated by the piston
drive.)
Mains power supply
failure
Uninterruptible power supply provided by internal battery
– Battery operation possible for at least 45 minutes, typi-
cally 150 minutes
– Automatic deactivation of the breathing system warmer
to increase battery runtime
Mains power supply
failure and battery
discharged
– Manual ventilation and spontaneous breathing are
available
– Emergency O
2
delivery (electronically controlled gas
mixer)
– Fresh-gas delivery (mechanically controlled gas mixer)
– Delivery of anesthetic agents via connected vaporizers
Failure of the central
gas supply system
– Use of the connected gas cylinders
Complete failure of
the gas supply
– 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
Flow measurement
failure
– Mechanical ventilation can be continued.
– Limitations with regard to displayed measured values,
measurement accuracies, and when triggering manda-
tory breaths are possible.
Failure of fresh-gas
delivery (electroni-
cally controlled
mixer only)
– Emergency O

delivery
For further information see: "Backup manual mode",
page 38.
– Anesthetic agent delivery from connected vaporizers
possible
– All ventilation modes are available.
Alternatively:
– Backup manual mode
