Irregular Pulse Rhythm Symbol
Pulse rhythm can be disturbed from talking, moving or
arrhythmias. This product displays «
» when the pulse
rhythm detected during measurement was irregular
(fi g.16).
WHO Classifi cation Symbol
Measured blood pressure values are classified against
WHO guideline. Scale, being lower right on display, allows
us to estimate the obtained figures according to the
classification
(fi g.17).
WHO scale is the scale classifi cation derived values of
blood pressure

Hypertension (severe) ≥180 ≥110
Hypertension (moderate) 160-179 100-109
Hypertension (mild) 140-159 90-99
High Normal 130-139 85-89

Optimal <120 <80
Pulse Pressure Display
This product calculates and displays pulse pressure
(fi g.18).
While systolic blood pressure keeps increasing with
age, diastolic blood pressure tends to start decreasing
at around age 50. Pulse pressure is value subtract
diastolic value from systolic value and therefore pulse
pressure tends to increase with age. Pulse pressure has
been considered to be related to stiff ness 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.
