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, tap Calcs .
2 Do the following for each measurement you want to take:
a Under Left or Right , select the measurement name.
b Using the touchpad or touchscreen, position the caliper at the peak systolic waveform, and then tap
.
A second caliper appears.
c Using the touchpad, position the second caliper at the end diastole point on the waveform.

Cardiac calculations
When performing cardiac calculations, the system uses the heart rate (HR) value present in the patient
information form. The HR value can be obtained in any four different ways:

Manual entry in the patient information form

Doppler measurement

M-Mode measurement

ECG measurement
The ECG heart rate measurement is only used if the other methods are not available. If the ECG
measurement is used, and the HR value in the patient information form is empty, the new HR value is
automatically inserted in the patient information form.
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.
