Measurements and calculations
You can perform basic measurements in any imaging mode and can save the image with the measurements
displayed. Except for the M Mode HR measurement, the results do not automatically save to a calculation
and the patient report. To save measurements as part of a calculation, you can first begin a calculation and
then measure.
Doppler measurements
The basic measurements that you can perform in Doppler imaging are:

Velocity (cm/s)

Pressure Gradient

Elapsed Time

+/x Ratio

Resistive Index (RI)

Acceleration
You can also trace manually or automatically. For Doppler measurements, the Doppler scale must be set to
cm/s on the Presets setup page.
To measure Velocity (cm/s) and Pressure Gradient
This measurement involves a single caliper from the baseline.
1 On a frozen Doppler spectral trace, tap Calipers .
A single caliper appears.
Delay Tap Delay , then select the position of the delay line on the ECG signal by tapping
one of the icons. The delay line indicates where the clip acquisition is triggered.
Select
Save to save the current position on the ECG signal. (You can change the
position of the delay line temporarily. Starting a new patient information form or
cycling system power reverts the delay line to the most recently saved position.)
Clips Tap Clips , then tap Time to change the clips control to ECG . With ECG , you have
the option to capture clips based on the number of heart beats. Tap the beats
control, then the up or down arrows, to select the number of beats. If Time is
selected, capturing is based on number of seconds. Select the time duration.
