Hypertension – high blood pressure
– is a killer. However, the good
news is that it is relatively easily
treated if identified early. This is
something that is achieved by measuring it in
a way with we are all familiar.
That method is probably older than
you think. The first measurement of blood
pressure was made in 1896 by squeezing
the flesh around an artery. This method
remains pretty much the most common
way to measure blood pressure 124 years
later, something that seems remarkably
anachronistic in the digital age.
Of course, there are many ways of
tracking changes in blood pressure and
a plethora of wearable and non-wearable
devices now on the market that do it. These
devices are not cuff-less, however. They
require the input of cuff-measured blood
pressure and then monitor changes over
the next few days. Then a new calibration is
necessary using a cuff again. That doesn’t
help the one billion plus people in the world
at risk of dying from hypertension because
they do not know they have it – once they
have used a cuff to calibrate a device, they
will know that they’re ill and don’t need
the device. Other wearable devices are
simply not medically accurate, which is even
worse.
THE CHALLENGE
What is needed, then, is a device that can
quickly and accurately measure blood
pressure in a home environment; is not cuffbased
and does not require calibration from a
formal test by a medical professional. Ideally,
the device should be small enough and cheap
enough to be built into every mobile phone. !
