Difference between upper-arm and
wrist measurement
The blood pressure measured with a watch-type
blood pressure monitor may differ from the
values measured on the upper arm. Measurement
with a wrist blood pressure monitor may show a
difference of up to 10 mmHg in a healthy adult.
In those who suffer from hypertension,
arteriosclerosis, diabetes, kidney failure and other
disorders of the circulation system, the difference
may exceed 10 mmHg. In that case measurement
on the upper arm is to be preferred.
In case of doubt, consult your doctor about the
best method in your case or make a comparison
between a measurement on the upper arm and
one on the wrist.
