Measurements and calculations
2
Drag the caliper to the peak of the heartbeat.
A second vertical caliper appears.
3
Drag the second caliper to the peak of the next heartbeat.
Saving the heart rate measurement to the patient report overwrites any heart rate entered on the patient
form.
Basic measurements in Doppler
The following basic measurement tools are available in Doppler: Heart Rate, Velocity (cm/s), Manual Trace,
Auto Measure, and Slope.
You can use these tools to measure:
To measure heart rate
“Basic measurements in M Mode”
, but start from a
frozen Doppler spectral trace.
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
Velocity
.
A single caliper appears.
If this control is hidden, tapping
More Controls
displays it.
