Acquiring Uterine Contraction Data
Fix the transducer. The transducer is retained on the midline half-way between the mother's
fundus and the umbilicus. The position is shown as figure5.1
The display of external pressure is shown as a percentage % of full scale. The uterine activity
reading at this point should be greater than 30 units and less than 90 units. If the reading falls
outside this range, the belt may be too tight or too loose.
③Zero can be set more quickly by pressing the AUTO ZERO button on the front panel, provided
the mother is not experiencing a contraction. The default contraction data will be 10% after press
the AUTO ZERO button.
Caution: Under no circumstances are transducers to be used to monitor patients under water.
Note: ① Do not use coupling gel on the TOCO transducer or transducer contact area.
② Check the function by TOCO transducer, and observe the change of relevant value.
5.1.3 Event Marker Recording of Fetal Movement
The event marker is a hand-held switch the mother takes. When FHR is monitored, she operates
the hand-held event marker press-switch when sensing fetal movement. At the moment, the mark
"↑" will show in the correspond position of trend wave. The count of fetal movement will add 1
after each push of the button. Push the button and hold for one second then release for counting
one fetal movement, the fetal movement will be only counted once if the button is pushed more
than one time during 5 seconds. And the mark will show in the bottom area of FHR wave display
section.
