Measuring blood pressure
Everybody’s blood pressure changes constantly. Fluctuations may be caused by mental
and physical factors (such as diet, exertion, smoking, caffeine or stress). Blood pressure
can also be affected by the time of day, time of year or temperature.
This blood pressure measuring device helps you to take regular, comparative
measurements. Individual, irregular measurements are therefore not very meaningful.
The guidelines for normal and high blood pressure (diastolic and systolic value) have
been defined by the World Health Organization (WHO) as shown in the following table.
