neonatal use. Please consult with your doctor or physician to use this product
to take blood pressure of child or person in pregnancy or under pre-eclamptic
condition.
METHOD OF MEASUREMENT
This product employs the oscillometric method for measurement of blood
pressure and pulse rate. Circuits within the cuff sense the small oscillations in
pressure against the cuff produced by the expansion and contraction of the
arteries in the wrist in response to each heart beat. The amplitude of each
pressure waves is measured, converted to millimeters of mercury, and
displayed on the LCD as a digital value.
FUZZY INFLATION
This product employs FUZZY inflation to ease stress on wrist during cuff
inflation.
By detecting pulse
signals while inflating,
this product is able to

determine the sufficient
pressure for each
measurement.
WHO CLASSIFICATION SYMBOL
Measured blood pressure values are classified against WHO guideline (1999).
The higher class applies when systolic and diastolic pressures fall into different
classes.
For specific information on your blood pressure, contact your physician. Never
make any judgment on your own based on the classification indication only.

PULSE PRESSURE DISPLAY
This product calculates and displays pulse pressure.
While systolic blood pressure keeps increasing with age, diastolic blood
TIME
pressure tends to start decreasing at around age 50. Pulse pressure is value
subtracting diastolic value from systolic value and therefore pulse pressure
tends to increase with age. Pulse pressure has been considered to be related
to stiffness of artery and has been studied as one of circulatory risk factors. It is
sometimes said that 45 mmHg of pulse pressure is normal value. Pulse
pressure only does not represent arterial sclerosis. However, observation of
pulse pressure in long term will be important.
