WARNINGS
To perform an Arterial calculation
After you perform arterial measurements, values in the ICA/CCA ratios are selectable on the arterial page of
the patient report.
1 On a frozen Doppler spectral trace, press the CALCS key.
2 Do the following for each measurement you want to take:
a Under Left or Right, select the measurement name.
b Using the touchpad, position the caliper at the peak systolic waveform.
c Press the SELECT key.
A second caliper appears.
d Using the touchpad, position the second caliper at the end diastole point on the waveform.
e Save the calculation as described in

VArty
Trace only a single heartbeat. The VTI calculation is not valid if measured with
more than one heartbeat.
Diagnostic conclusions about blood flow based on VTI alone can lead to
improper treatment. Accurate blood flow volume calculations require both the
vessel area and velocity of blood flow. In addition, accurate blood flow velocity
is dependent on a correct Doppler angle of incidence.
