Measurement Method
THIS upperarm digital sphygmomanometers measure blood pressure and
pulse by using what's called the
method, meaning the
oscillometric
measure the fluctuations in pressure. This is done by first wrapping a
fitted cuff around the upperarm. The monitor then automatically fills the cuff
with air creating pressure around the arteries inside the upperarm. 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 upperarm 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.

THIS monitors are not safe and accurate to use with arrhythmias such as
atrial or ventricular premature beats and atrial fibrillation.
