Actogram
Note
: the Actogram feature is not available in the USA and Canada.
Actogram uses the low-frequency content of the signal from the ULT1 ultrasound
transducer to detect fetal movements, and give an activity profile of the fetus.
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 movement).
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%.

Data storage (paper-out buffer)
FM800E does not store the Actogram event marks, activity graph or threshold value.
217B
Twins
Actogram should not be used when monitoring twins, as it
can confuse fetal movements from twins.
Some Actogram ‘fetal events’ may have another cause, e.g.
maternal movement. It may be useful to get the mother to
confirm fetal movement using the event marker button.
