3) Connect the IUP cable to the connecting cable. (They might have already been securely
connected in the package.)
4) Plug the connecting cable to the TOCO/IUP socket of the monitor.
5) Momentarily pressing the re-zero button on the IUP cable. The green light on the cable will
flash for five seconds. During that time, zero the F9 Monitor by pressing the
AUTO ZERO
button. Make sure the display value and the trace are both “0”.
6) Ask the mother to cough. A spike on the trace in response to the cough indicates proper
positioning and function of the IUPC.
7) Flush as needed during monitoring. A spike on the tracing will appear during flushing.
7.6.4 Checking Intrauterine Pressure Cable Function
To test an IUP cable’s function:
1) Disconnect the catheter from the cable. Insert the cable check plug into the catheter end of
the cable. (See Figure 7-4).
Figure 7-4: Test the Pressure Cable
2) Verify that the green light is continuously lit (not flashing).
3) If the light does not illuminate, replace the cable.
NOTE: If the light is flashing, verify that the cable check plug is inserted completely
into the cable.
WARNING : The cable test function is not intended to check the accuracy of
the system, only to confirm cable function.
7.7 Monitoring Fetal Movement
7.7.1 Auto Fetal Movement (AFM) Monitoring
Auto fetal movement is also detected from the ultrasound Doppler signal. The fetal movement
signals differ from the Doppler heart rate signal in that they have larger extent and lower frequency.
The larger extent is due to the bigger scope of moving areas (e.g., the fetal arms or legs); lower
frequency is due to the lower velocity of the fetal movements compared with those of the fetal heart.
