Measurement Method
THIS wrist digital sphygmomanometers measure blood pressure
and pulse by using what’s called and
oscillometric
method,
meaning they measure the fluctuations in pressure. This is done
by first wrapping a fitted cuff around the wrist. The monitor then
automatically fills the cuff with air creating pressure around the
arteries inside the wrist. Mounted inside of the cuff is a special
gauge that is capable of sensing the small
oscillations
(fluctuations)
in pressure. These fluctuations are produced as a result of the
pressure the cuff has placed around the wrist and are, in a basic
sense, the arteries contracting (getting larger and smaller) with
each heart beat. The monitor then measures how high and how
quickly these contractions occur and converts that information into a
digital value. A special valve, called an electrode, deflates the
monitor automatically when the measurement is complete.
