Preparing to Monitor

Prepare for ultrasound monitoring using the list below. The standard procedures in use in your facility
determine the sequence of actions.
Determine fetal position.
1
Fasten the belt around the patient.
2
3
Switch on the monitor and the recorder.
Connect the transducer to a free socket. The signal quality indicator for the heart rate initially
4
displays an invalid signal.
Apply a thin layer of ultrasound gel to the underside of the transducer.
5
CAUTION
Using ultrasound gel not approved by Philips may reduce signal quality and may damage the
transducer. This type of damage is not covered by warranty.
Place the transducer on the abdomen, if possible over the fetal back or below the level of the
1
umbilicus in a full-term pregnancy of cephalic presentation, or above the level of the umbilicus in
a full-term pregnancy of breech presentation. Work the transducer in a circular motion to ensure
the gel layer makes good contact.
When the transducer is connected correctly and you receive a good signal, the signal quality
2
indicator should be filled out. If an inadequate signal is produced, the signal quality indicator will
indicate a poor signal, and no numeric will appear on the screen.
3
Adjust the audio volume of the monitor's loudspeaker to a clearly audible level, while moving the
transducer over the abdomen. When you have a good signal, secure the transducer in position
below the belt.
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.
The ultrasound transducer may warm slightly (less than 1°C/1.8°F above ambient temperature) when
applied to the patient. 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.
