Q
When should I measure my blood pressure?
A
We recommend three measurements a day.
First.Upon Waking (Because, with almost no influence from body
movement, it's the blood pressure is closest to that at night.)
Second... Before Lunch (Because it provides blood pressure values
close to the highest of the day.)
Third.At Bedtime (So as to obtain data close to your average blood
pressure values during the day.)
This way, by taking measurements morning, noon and night, you can
use the unit to learn the patterns of and monitor your blood pressure.
Q
Why are measured blood pressure values different each time I take
a measurement?
Blood pressure changes even within a single
day, and it is different depending on the
measurement posture. Because of this, when
taking measurements, be sure to always take
measurements under the same conditions.
For persons taking blood pressure medication,
blood pressure may change greatly due to the
effects of the medication.
When taking 2 measurements in succession, be
sure to stay quiet for 4 to 5 minutes after the first
measurement before taking the next measurement.
Q
Why are the measured values different for the left and right arm?
It is said that differences in blood pressure
values between the left and right arms may be
around lOmmHg. The blood pressure can be
measured in either the left or right arm, but all
measurements should be taken using the same
arm for comparative consistency.
