value exceeds the normal range. When a
patient’s systolic and diastolic blood
pressures fall into different categories, the
higher category should apply.
Only a physician can tell you your normal
blood pressure range and the point at which
you are at risk. Consult your physician to
obtain these values. If the measurements
taken with these products fall outside the
range, consult your physician.
Why does my blood pressure fluctuate
throughout the day?
Individual blood pressure varies greatly both on a
daily and a seasonal or temperature basis. These
variations may be more pronounced in
hypertensive patients. Normally the blood
pressure rises while at work and is at its lowest
during sleep.
The graph below illustrates the variations over a
single day with measurement taken every 5
minutes. The thick line represents sleep time. The
rises in blood pressure at 4PM (A in the graph)
and 1 2AM (B in the graph) correspond to an
attack of pain and sexual intercourse
(Beven,
Honour & Stott, Clin. Sci. 36:329, 1969).
HOW THE BLOOD PRESSURE MONITOR
WORKS
This product uses the Oscillometric Measuring
method to detect your blood pressure. Before
every measurement, the unit establishes a
“
zero
pressure
”
equivalent to the air pressure.
Then it starts inflating the arm cuff to 180mmHg
or higher until it senses that it has blocked your
blood in the artery.
After that, the deflation process starts, during
which time the unit detects pressure oscillations
generated by beat-tobeat pulsatile, which is used
to determine the systolic, mean and diastolic
pressure, and also your pulse rate. Any motion
during this period will result in an incorrect
measurement.
After all readings are determined and displayed
on the LCD, the measurement is finished and the
arm cuff automatically deflates.
