Fetal Heart Rate Monitoring: Ultrasound (External Method)
Strip Chart Annotations
When fetal movement detection is enabled , the mode annotation
FMD
is printed on the center margin. The annotation only provides an
indication that the feature is enabled—it does not indicate detection.
When fetal movement is detected , a solid line is automatically marked on the bottom
of the heart rate grid for the duration of the detected movement. (Refer to Figure 5-
1 .)
Using the Remote Event Marker to Complement the Patient Record
The Remote Event Marker is an accessory that can be used to complement the
patient record. The annotation resulting from the Remote Event Marker can be
configured as one of the following:
„
: commonly used to record a general event; or
„
: commonly used as an indication that the mother has perceived fetal
movement. (This is the factory default setting.)
Instruct the mother to press the button on the Remote Event Marker whenever she
feels fetal movement. Ask her to hold down the button for the duration of the
perceived fetal movement. The annotation, or
, is printed on the strip chart in
addition to a horizontal bar for as long as the Remote Event Marker button is held
down. (Refer to
Figure 5-1 .)
