b Position the calipers by dragging.
c Tap to save the measurement.
4 Calculate the blood velocity.
a On a frozen Doppler trace, on the Volume Flow menu, tap TAP (peak). To use a different velocity
measurement, tap , and then choose either Mean or Manual .

Arterial calculations
The Arterial calculations that you can perform are listed in Table 5-3 on page 5-15.
In the Arterial exam, you can also calculate ICA/CCA ratio, volume, volume flow, and percent reduction. See
“Volume calculation” on page 5-12, “Volume flow calculation” on page 5-12, and “Percent reduction
calculations” on page 5-11.
WARNINGS

To avoid incorrect calculations, verify that the patient information, date, and
time settings are accurate.

To avoid misdiagnosis or harming the patient outcome, start a new patient
form before starting a new patient exam and performing calculations. Starting
a new patient form clears the previous patient’s data. The previous patient’s
data will be combined with the current patient if the form is not first cleared.
See “Entering patient information” on page 4-31.
