1 On a frozen M Mode trace, press the CALCS key.
2 Select FHR from the calculations menu. A vertical caliper appears.
3 Using the touchpad, position the vertical caliper at the peak of the heartbeat.
4 Press the SELECT key. A second vertical caliper appears.
5 Using the touchpad, position the second vertical caliper at the peak of the next heartbeat.

To calculate the S/D ratio, RI or PI of the Middle Cerebral Artery (MCA) or Umbilical Artery
(UmbA)
Note
1 Select OB exam type, and select LMP or Estab.DD in the patient information form.
2 On a frozen Doppler spectral trace, press the CALCS key.
3 Do the following for each measurement you need to take:

b Position the calipers:
For S/D, RI, position the first caliper at the peak systolic waveform. Press the SELECT key, and
position the second caliper at the end diastole on the waveform.
For S/D, RI, PI, position the caliper at the beginning of the desired waveform, and press the
