Oscillometric Measuring method
This
produc
t uses the
Oscillom
etri
c
Measuring method to dete
c
t blood pressure. Before
every
measurement, the unit establishes a “zero pressure”
equivale
nt to the air pressure. Then it starts
g the arm
cuff
, meanwhile, the unit dete
c
ts pressure
s generated by beat- to- beat
e, w
hic
h is used to determine the systoli
c
and diastoli
c
pressure, and also pulse rate.
The d
