Measurement Method
HL858CG Automatic Upper Arm Blood Pressure Monitor measures
blood pressure and heart rate by oscillometric method, meaning the
fluctuations in pressure are measured. Once the cuff is wrapped
around your upper arm, just turn on the monitor and inflation
automatically starts. The inflation of the cuff creates pressure around
the arteries inside upper arm.
Within the cuff is a gauge which senses the fluctuations (oscillations)
in pressure. The fluctuation measured represents the degree of
intensity that your arteries contracting with each heart beat, and also
a result of the pressure that the cuff has placed on the upper arm. The
monitor measures these contractions and converts the information to
a digital value. This is the result displayed on the monitor screen.
Once the measurement is complete, the cuff will automatically deflate.
Note!
