Measurement Method - Digipulse MW-300C Instruction Manual

They are noninvasive, meaning no part of the monitor enters your
body, and provide systolic, diastolic and pulse measurements.
This wrist digital sphygmomanometers are recommended for use by
people over the age of 18 and are not suitable for clinical use.

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
