Measurements
Vascular calculations
The vascular measurements that you can save to
the patient report are listed in the following table.
For definitions of acronyms, see “Glossary” on
page 167
.
To perform a Vascular calculation
After you perform vascular measurements, values
in the ICA/CCA ratios are selectable on the vascular
page of the patient report.
1 On a frozen Doppler spectral trace, press the
CALCS key.
2 From the calculations menu, select Left or
Right.
WARNING:
To avoid misdiagnosis or harming
the patient outcome, start a new
patient information form before
starting a new patient exam and
performing calculations. Starting a
new patient information 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
“To create a new patient
information form” on page 36.
WARNING:
To avoid incorrect calculations,
verify that the patient information,
date, and time settings are
accurate.
