4 Events and Alarms
4.1 Recording fetal movement events
Fetal movements are recorded by the mother operating a hand-held push-button
event marker. When an event is noted, a solid triangular event mark is printed at the
top of the fetal heart rate trace. The Team beeps, if the audible beep is switched on.
1 Connect the event marker to the jack socket on the rear of the Team base unit.
2 Give the event marker to the mother. Tell her to press the button every time a
fetal movement is felt.
To turn the audible beep off or on
1 Press [MENU] once.
2 Select [ALARM].
3 Press [FETAL MOVEMENT].
4 Select [SILENT EVENT] or [AUDIBLE EVENT].
4.2 Actogram
Note
: the Actogram feature is not available in the USA and Canada.
Actogram uses the low-frequency content of the signal from the 1.5 MHz ultrasound
transducer to detect fetal movements, and give an activity profile of the fetus.
WARNING: ACTOGRAM IS NOT INTENDED FOR USE DURING LABOUR.
Recorded activity represents fetal movements (breathing, limb and trunk movement)
or non-fetal movements (transducer movement, maternal coughing or other move-
ment).
The Actogram value can be printed as a line graph on the contractions trace, or as
fetal event marks above the trace, or both. An event mark is printed every time the
amplitude goes above a set threshold. The default threshold is 40% of full scale
deflection, but it can be set to any value in the range 0-99%.
