M Mode measurements

The basic measurements that you can perform in
M Mode imaging are as follows:
• Distance in cm/Time in seconds
• Heart Rate (HR) in beats per minute (bpm)
The time scale above the trace has small marks at
200 ms intervals and large marks at one‐second
intervals.
To measure distance (M Mode)
You can perform up to four distance
measurements on an image.
1 On a frozen M Mode trace, press the
key.
A single caliper appears.
2 Using the touchpad, position the caliper.
3 Press the key to display the second
SELECT
caliper.
4 Using the touchpad, position the second
caliper.
See "To save a measurement to a calculation and
patient report" on page 47.
To measure heart rate (M Mode)
1 On a frozen M Mode trace, press the
key.
2 Select HR on‐screen.
A vertical caliper appears.
3 Using the touchpad, position the vertical
caliper at the peak of the heartbeat.
4 Press the
A second vertical caliper appears.
5 Using the touchpad, position the second
vertical caliper at the peak of the next
heartbeat.
See "To save a measurement to a calculation and
patient report" on page 47. Saving the heart rate
measurement to the patient report overwrites
any heart rate entered on the patient information
form.
See also "To measure fetal heart rate (M Mode)"
on page 71.

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), and Acceleration. You can also trace
manually or automatically.
CALIPER
For Doppler measurements, the Doppler scale
must be set to cm/s. See "Presets setup" on
page 22.
To measure Velocity (cm/s) and Pressure
Gradient (Doppler)
1 On a frozen Doppler spectral trace, press the
CALIPER
A single caliper appears.
2 Using the touchpad, position the caliper to a
peak velocity waveform.
This measurement involves a single caliper from
the baseline.
