AI + Blood Pressure Measurement
Measuring AI + Blood Pressure Together
How to incorporate the Tonogram display for a more accurate measurement: A tonogram
shows the output of an AI pulse wave sensor. The positional relationship of the AI pulse wave
sensor and an artery can be estimated from a tonogram. [Fig. 4]
The values around the peak of the tonogram (around the center of an artery) are calculated.
[Fig. 4]
The center peak represents the ideal measurement. Measurement is also possible with an
ascending line to peak, a descending line to peak or a descending line to peak (see above);
however, it is also possible that an accurate pulse wave may not be taken. If only one outer
indicator light is on, reattach the AI pulse wave sensor and measure again.
Measurement is impossible even if the tonogram shows an ascending, descending or flat
line (see above). When re-measuring with an ascending or descending line, it is possible to
adjust the position of the AI pulse wave sensor by sliding it instead of having to remove and
reattach the unit. The artery is located in the direction of the LED lights that are lit. While
pressing in the slide stopper, adjust the pulse wave sensor by one or two scale units (black
lines on the casing) in that direction.
