Figure 5.1 Ultrasound Transducer & TOCO Transducer Positioning
5.1.1 Ultrasound Monitoring of FHR
Ultrasound monitoring can be used or antepartum monitoring; it is a method to obtain FHR
through maternal abdominal wall. Put the FHR transducer on maternal abdomen to transmit lower
energy ultrasound wave to etal heart, then receive the echo signal rom it.
Operation Procedure:
1Preparing the Monitor
Turn the monitor on and veri y that the normal monitoring screen appears on the display.
Check the ultrasound transducer to veri y proper attachment to the monitor. For twins monitoring,
make sure the second ultrasound transducer i properly connected.
Set the current heart rate channel to channel US1, and adjust FHR1 volume well.
Attach the buckle o the ultrasound transducer to the belt. Apply aquasonic coupling gel to the
ace o the transducer.
2 Acquiring the Fetal Heart Signal
Determine the location o the etal heart using palpation or a etoscope.
Place the ultrasound transducer on the abdomen over etal site and move it slowly until the
characteristic hoo -beat sound o the etal heart is heard. And then ix up the ultrasound transducer.
The elasticity o belt can be adjusted, which make the patient monitored in the com ortable
situation, and the etal heart rate value will be shown on the screen. At the same time, the
ultrasound wave will be drawn in green color on the screen.
3 Acquiring Twins’ Heart Rates Signal
CMS800G is able to monitoring twins’ heart rates through two ultrasound transducers during the
whole pregnant time.
Follow the step②mentioned above to acquire the heart rate or the irst etus.
Set the current heart rate channel to US2, and adjust FHR2 volume well so that the second heart
sounds can be heard
