F9 Fetal & Maternal Monitor • User Manual
- 45 -
Connect the US transducer to the US1 socket; connect the DECG cable to the DECG socket.
Monitor one twin with a US transducer using the procedures described in Section 7.2.
Monitor the second twin with a DECG cable using the procedures supplied by the manufacture.
CAUTION :
The US transducer must be connected to the US1 socket. If the US transducer
connects to the US2 socket while the DECG cable is connected to the DECG
socket, the FHR trace and numeric from US2 will not be displayed.
7.4.3 Signals Overlap Verification (SOV)
When monitoring twins, there are possibilities that one twin’s FHR signal is mistaken for the other
one’s signal. The F9 Monitor provides a signal overlap verification (SOV) function to reduce these
possibilities.
In the process of monitoring, if the SOV detects signals overlapping, an alarm message “Signals
Overlap (FHR1, FHR2/DFHR)” will appear on the screen to warn you. It may be necessary to check
the patient and reposition the transducers.
7.4.4 Changing FHR2/DFHR Offset
In order to distinguish the FHR1 trace from the FHR2/DFHR trace, FHR2/DFHR offset is provided
to help you separate the two traces by an offset of -20 bpm or +20 bpm.
1) Select the Setup key on the main interface.
2) Select
Recorder FHR2 Offset
.
3) Select
-20 bpm
(default),
0 bpm
or
+20bpm
.
4) Select
OK
.
The following preset FHR2/DFHR offset will be printed on the recorder paper every 10 minutes.
“FHR2/DFHR: -20bpm”: the FHR2/DFHR trace is 20bpm lower than it really is.
“FHR2/DFHR: +20bpm”: the FHR2/DFHR trace is 20bpm higher than it really is.
