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.
Figure 7-14 Test the Pressure Cable
2) Verify that the green light is continuously lit (no flashing).
3) If the light does not illuminate, replace the cable.
NOTE:
1 If the light is flashing, verify that the cable check plug is inserted completely into the
cable.
2 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
During fetal heart monitoring with ultrasound, the fetal movement signals are also detected. The
fetal movement signals differ from the Doppler heart rate signals in that they have larger extent
and lower frequency. The larger extent is because of the bigger scope of moving areas (e.g., the
fetal arms or legs); lower frequency is because of the lower velocity of the fetal movements
compared with those of the fetal heart.
Only US1 channel can perform AFM. But be aware that when monitoring twins, the movements
detected by US1 may also be caused by the second fetus‟s movement.
The movement of the fetus will be detected and displayed in the form of a trace on the screen and
the recorder paper.
There are two ways to monitor automatic fetal movement (AFM): wired monitoring and wireless
monitoring. Wired AFM monitoring is monitored by wired ultrasound transducer while wireless
AFM monitoring is monitored by wireless ultrasound transducer (US-T transducer). AFM can be
monitored simultaneously with FHR. Be aware that only when the wired ultrasound or the US-T
transducer is connected to US1channel can AFM be monitored.
