The adaption of default settings can only be done in standby and is protected by a password.
For adapting the settings, please contact the responsible person in your organization and check
the instructions for use. If further help is required, please contact your local Dräger
representative.

WARNING
: If the device configuration is not adapted for the use in long-term ventilation, the
active settings (especially the above mentioned settings) have to be checked and adapted
particularly carefully whenever a new patient case is started.

System Test
-
The
devices are designed to be tested every 24 hours
to ensure readiness for operation. If
the device test is not done, the readiness of operation is not tested, and particularly the flow
measurement may become inaccurate.
In general, never rely on a single measured value
for clinical decisions.
Unlike many ICU ventilators, the flow measurement of the anesthesia
device cannot be calibrated during operation. Measured values may change their color to
indicate an inaccurate status. The accuracy of gas measurement should not be affected
because the gas measurement modules perform a zeroing during operation independently of
the system test, except the mainstream O
2
-sensor of the Fabius family. Please be aware that
the anesthesia devices may raise technical alarms regarding required calibrations of flow
measurement and the Fabius FiO
2
measurement; nevertheless these values can be used in the
case of long-term ventilation.
If in doubt, perform a system test.
-
Each time the anesthesia device is prepared for long-term ventilation of a new patient, perform
a complete system test (not only a leakage test).
