3-3. Measuring blood velocity
3-3-1. Normal mode
This section explains the fundamental use of measuring blood velocity.
Refer to “§ 4. MENU and Mode settings” for various uses.
(1) Put ultrasonic gel on the probe top or
patient skin.
(2) Put the probe on the measurement area
and move it slowly to locate the point
where the maximum Doppler sounds are
heard. An ideal probe angle to the vessel
is approximately 45° to 60
°
.
(3) When the waveform becomes rhythmical
and stable, wait more than 5 sec. without
moving probe and press the probe
button to freeze the waveform.
Note: Pressing probe button longer than 2 sec.
will turn the unit OFF.
(4) To get numerical data, press BACK
button or go to menu and change the
DISP mode to DATA.
Note: See Ҥ 4-2-g. DISP" for operation. Also,
see “§6-3. Numerical Data” for the
parameters.
