5.
The applied pressure will become constant and a pulse
wave will form in the upper-left part of the screen. Instruct
the patient not to move while the measurement is in
progress. Body movements and vibrations can cause a
measurement error to occur. [Fig. 4]
If body movement or vibrations cause a measurement error the
measurement will automatically stop. (Refer to Section 21.)
If the AI value goes outside of the 30%-150% range, the AI [Fig. 4]
measurement results will not be displayed for each beat. Check to
make sure that there is no abnormality in the pulse waveform. This
will also cause a break in the graph of the AI values plotted for each
pulse wave.
If the pulse is irregular or too faint, the device may not detect the
pulse wave, in which case there will be no pulse waveform and
nothing displayed on the graph.
A green bar in the far lower-left part of the screen shows
measurement progress toward completion.
6.
Once measurement is complete the results will appear.
[Fig. 5]
The green “SAVING” message will appear in the lower-left
part of the screen and the data will be recorded on the
memory card.
Do not eject the memory card while save is in progress. This
could result in damage to the device.
7.
The beep to indicate that the data has been saved will
sound and the dark blue message “COMPLETE” will
appear in the lower-left part of the screen. [Figs. 6 and 7]
The representative pulse wave (AVG) displayed on the screen
is selected among all detected pulse waves. It has a stable
pulse wave and the closest AI value to the average. Still, there
may be some difference between AVG and the average.
