Influencing
and evaluating
readings
THEREFORE WE RECOMMEND:
Take a blood pressure reading daily and on a regular basis,
even if you are experiencing no apparent complaints.
The following table shows the classification of high and low blood pressure,
without taking age into consideration. These values were determined by the
World Health Organization (WHO).
Low blood pressure
Normal blood pressure
systolic below 100
systolic 100–140
diastolic below 60
diastolic 60–90
Types of high blood pressure
Stage 1
Stage 2
Stage 3
mild hypertension
medium hypertension
serious hypertension
systolic 140–159
systolic 160–179
systolic above 180
diastolic above 90
diastolic above 95
diastolic above 110
There are many factors that can influence blood pressure. Readings can be
affected by stress, fear, heavy physical exertion or the time of day at which they
are taken. Your personal blood pressure values are subject to considerable
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 asleep.
• 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
several 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.
