2.6 Fluctuations in blood pressure
There are many factors that can influence blood pressure. Readings can be affected
seriously by stress, fear, heavy physical exertion or the time of day at which the
measurements are taken. Your personal blood pressure values are subject to consi-
derable fluctuation during the course of the day and the year. These fluctuations
are particularly pronounced in the case of patients suffering from hypertension.
Blood pressure is usually at its highest during physical exertion and at its lowest at
night when you are asleep.
2.7 Influencing and evaluating readings
• Measure your blood pressure several times, then record and compare the results.
Do not draw any conclusions from a single reading.
• Your blood pressure readings should always be evaluated by a doctor who is also
familiar with your personal medical history. When using the unit regularly and
recording the values for your doctor, you should visit the doctor from time to time
to keep him updated.
• When taking readings, remember that the daily values are influenced by several
factors. Smoking, consumption of alcohol, drugs and physical exertion influence
the measured values in various ways.
• Measure your blood pressure before meals.
• Before taking readings, allow yourself at least five minutes rest.
• If the systolic and diastolic readings seem unusual (too high or too low) on seve-
ral occasions, despite correct use of the unit, please inform your doctor. This also
applies to the rare occasions when an irregular or very weak pulse prevents you
from taking readings.
