9. WHO trafc light function
The unit categorises the blood pressure readings according to the guidelines of
the World Health Organisation (WHO). You can use the coloured elds to read the
categorisation of each reading:

10. Pulse pressure
The pulse pressure – not to be confused with the pulse beat – provides an
indication of the stretchability of the blood vessels. A hard system of vessels
can have a negative effect on the cardiovascular system. Studies show that the
cardiovascular risk increases if the pulse pressure value is consistently greater than
65 mmHg.
– Lower dot (Green) signies normal value
– Middle dot (Yellow) signies borderline value*
– Upper dot (Red) signies high pressure*
The categorisation according to WHO is stored with the readings and can be called
up again together with the readings from the memory.
The heart works in two phases, the contraction phase (systole) and the relaxation
phase (diastole). The pressure difference between systole and diastole is called the
pulse pressure or pulse amplitude. The higher the pulse pressure, the harder the
vessels.

High pulse pressure above 65 mmHg
Increased pulse pressure 55 to 65 mmHg
Normal pulse pressure below 55 mmHg
If your pulse pressure is permanently above 55 mmHg, consult your doctor.
