The graph above 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 12AM (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 wrist 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-to-beat 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 wrist cuff automatically deflates.
