9.Measurement Preparation
3.
Locate the radial artery by palpation.
Once you have located the radial artery, use a
commercially-available, non-permanent felt tip
marker to mark the spot on the artery which will be
best for your AI pulse wave measurement.
A proper measurement can only be done over the
bone at the radial artery.
4.
Attach the AI pulse wave sensor unit.
Remove the pulse wave sensor unit from its storage
clip and centre the two intersecting black lines on the
sensor unit frame (the point where the reading is
taken) over the wrist artery spot you marked in
above. Align the wrist wrinkle just below the palm
with the inner edge of the frame. Use the hook and
loop fastener to hold the unit in place. [Figs. 21-22]
5.
Confirm the artery's position again.
Confirm if the AI pulse wave sensor unit frame's
black lines intersect the artery by palpation.
[Figs. 23-24]
* Instruct the patient to relax and not to move.
* If misaligned, go back to 4. above.
6.
Adjust the sensor. [Figs. 25 and 26]
Adjust the AI pulse wave sensor by pressing in the
slide stoppers on both sides.
Continue moving the AI pulse wave sensor until the
black line on the AI pulse wave sensor is aligned
with the centre (longest) line of the AI pulse wave
sensor unit's outer shell.
* The AI pulse wave sensor unit can be moved slightly by
pressing the slide stoppers at both sides.
* Return the AI pulse wave sensor to its original position
after measurement.
