Step 1: Preparing the Monitor
Turn the monitor on and verify that the normal monitoring screen appears on the display. Remove
the monitor from service if an error occurs.
Check whether the monitor is powered from the internal battery or AC power. If operating on the
internal battery, check the power status frame on the display to determine whether the battery has
sufficient charge to complete the monitoring session. Use the AC power if the battery is too low.
Check the ultrasound transducer to verify proper attachment to the monitor. For twins monitoring,
make sure the second ultrasound transducer is properly connected.
Adjust heart rate channel one speaker volume to middle level. Adjust channel two speaker volume to
off if monitoring twins.
Apply ultrasound gel to the face of the transducer.
Step 2: Acquiring the Fetal Heart Signal
Determine the location of the fetal heart using palpation or a fetoscope. Place the transducer on the
maternal abdomen and listen for the fetal heart signal. Reposition the transducer for the loudest fetal
heart signal and verify the heart shape icon on the screen is blinking at the fetal heart rate.
Secure the ultrasound transducer with the elastic belt. Make sure the transducer is still positioned for
the loudest fetal heart signal.
Verify the monitor is displaying fetal heart rate values and that the heart shape icon on the screen is
blinking at the measured heart rate.
Step 3: Acquiring Twins' Heart Rates
Follow the steps outlined in step 2 above to acquire the heart rate for the first fetus.
Adjust the ultrasound audio volume for channel one down and channel two up so that the second
heart sounds can be heard.
Determine the location of the second fetal signal using palpation or fetoscope.
Apply gel to the second ultrasound transducer and place it on the maternal abdomen where the
second fetal signal was located. Adjust the position of the transducer to find the fetal signal and to
maximize its loudness.
Secure the ultrasound transducer with the elastic belt. Make sure the transducer is still positioned for
the loudest fetal heart signal. Also verify the position of transducer one has not changed.
Verify the monitor is displaying fetal heart rate values for both fetuses and that the heart shape icons
both on the screen are blinking at the measured heart rate.
Step 4: Monitor Adjustments
Readjust the volume settings for the desired loudness.
