Measurement Preparation
How to Apply the AI Pulse Wave Sensor Unit
Proper posture
Adjust the height of the chair to align the height of the wrist
with the height of the heart. By sitting back and keeping the
back straight, the arm will naturally be straight.
[Figs. 12 and 13]
* Place the AI pulse wave measurement unit on a flat, horizontal
(non-sloping) surface.
* When measuring with the left arm, place the AI pulse wave
measurement unit on the left side of the patient. (The wrist
rest is set up for a left hand as the initial configuration.) Adjust
the elbow placement board of the AI pulse wave
measurement unit according to the length of the arm of the
patient. (The elbow placement board can be extended
approximately 10 cm.) [Fig. 14]
* Instruct the patient to relax and not to move during measurement.
Place the wrist.
1
Place the thumb on the side of the wrist rest indicated by
the "thumb side" printing on the wrist rest.
[Fig. 15 and 16]
Align the wrinkle of the wrist joint with the wrist position
mark on the wrist board. [Fig. 15]
* Instruct the patient, saying "relax your hand". Patient's
palm will face the front naturally. (It should be a little
limp.)
The wrist rest has a slope of approximately 30 degrees.
When putting one's hand along the slope of the wrist rest,
the wrist goes up by a slope of approximately 30 degrees.
* When measuring with the right arm, adjustment of the wrist
rest will be required. Remove the wrist rest from the top of
the AI Pulse Wave Measurement Unit. Turn it so that the
"thumb side" is facing the opposite direction. Reinsert the
wrist rest on the top of the AI Pulse Wave Measurement
Unit. You will now have the correct slope for a right hand
measurement. Tilt the wrist to turn the thumb up.
Adjust the elbow placement board.

measurement unit according to the length of the arm of the
patient. [Fig. 14]
