10 Monitoring FHR and FMP Using Ultrasound
99
WARNING
Periodically compare the mother's pulse with the signal coming from the monitor's loudspeaker to
ensure that you are monitoring fetal heart rate. Do not mistake a doubled or elevated MHR for FHR.
Note that when applied to the patient, the ultrasound transducer may warm slightly (less than 1°C/
1.8°F above ambient temperature). When NOT applied, the transducer can reach a maximum
temperature of 44°C/112.2°F at an air temperature of 40°C/104°F.
Selecting Fetal Heart Sound
You can listen to the fetal heart sound from
one
ultrasound transducer at a time. When the fetal heart
sound is selected for a FHR channel, you see the audio source symbol
next to the FHR numeric
label for that channel.
To select the audio source for a FHR channel:
Enter the
Setup FHR1
menu for the channel you want to hear (FHR1 used as an example).
Press
Select Audio
. It may take a few seconds for the audio source symbol
to appear.
Changing the Fetal Heart Sound Volume

Fetal Heart Sound Volume
window gives you an
indication of the current volume. To change the volume:
1
