Accuracy

Walgreens monitors have been clinically tested against a
scientific device called a sphygmomanometer, considered the
gold standard in blood pressure measurement. All Walgreens
monitors have performed equivalent to measurements taken
with this scientific device and are within the accuracy limits
prescribed by the American National Standard for Electronic
or Automated Sphygmomanometers.

Measurement Method

Walgreens monitors measure blood pressure and pulse
by using what's called an oscillometric method,
meaning they measure the fluctuations in pressure. This
is done by first wrapping a fitted cuff around the upper
arm. The monitor then automatically fills the cuff with air
creating pressure around the arteries inside of the arm.
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 arm and
are, in a basic sense, the arteries pulsing (getting larger and
smaller) with each beat. The monitor then measures how
high and how quickly these pulses occur and converts that
information into a digital value. A special valve, called an
electrode, deflates the monitor automatically when the
measurement is complete.

Special Conditions

All Walgreens blood pressure monitors are safe and accurate
to use with arrhythmias such as atrial or ventricular premature
beats and atrial fibrillation.
