Duo Sensor Technology
The innovative
Duo Sensor
Technology
combines two
professional
measuring tech-
nologies: the oscillometric technol-
ogy and the Korotkoff's technology.
Whilst most automatic blood pres-
sure devices only use oscillometric
technology, Duo Sensor Technology
also utilises Korotkoff's highly
accurate method of blood pressure
measurement, which is also used
by doctors to measure blood pres-
sure.
Korotkoff's principle of blood pres-
sure measurement is characterised
by its reduced susceptibility to
malfunction, producing correct
measured values even in patients
with a variety of heart rhythm
disorders.
Doctors use a stethoscope to listen
to the so-called Korotkoff sounds
and thereby to determine blood
pressure; the
Tensoval duo
control does
exactly the
same via an
integrated
microphone.
Duo Sensor
Technology
There are few people whose pulse
sounds are so faint that they can-
not be picked up by Korotkoff's
method. In these cases, Duo Sensor
Technology will automatically kick
in to display the oscillometric blood
pressure measurements based on
arterial pulse waves rather than
pulse sounds.
Duo Sensor Technology thus pro-
duces accurate results and is still
easy to use.
Comfort Air Technology
The Comfort Air
Technology
enables approxi-
mate determina-
tion of the systolic
blood pressure
value during inflation, and on that
basis the individually required infla-
tion pressure for blood pressure
measurement. This allows measure-
ments on the upper arm to be
taken with less discomfort.
