Biomedical Support
This section of the appendix is designed for the Biomedical personnel of your
hospital. It includes an overview of the Biomed menu, basic setup, saving setups,
diagnostic functions, and calibration check procedures for NBP. This appendix is not a
substitute for the Infinity Vista Service Manual that is available from Dräger.
Startup Tests
The monitor runs internal tests continuously and upon power up to check various
functions, as well as the integrity of both ROM and RAM memories. If any of the tests
fail, the monitor resets and displays a message (see the following table). The test
results are recorded in the Diagnostic Log.
If the same error is detected three times in succession within 10 minutes without any
other intervening errors, the monitor stops resetting and generates a loud, continuous
error tone. If this happens, take the unit out of operation and call DrägerService.
CAUTION:
Verify that the monitor’s line frequency under the “Service” menu is set to
match the 50 or 60 Hz mains power line frequency of your hospital. The line frequency
determines the center frequency of the ECG notch filter. The filter greatly reduces line
frequency noise on the ECG waveform. Refer to the Service manual for details how to
change frequency.
NOTE: The monitor stores patient data and settings in an internal battery backed-up
memory. If any of the following messages appear frequently, the internal battery needs
to be changed.
