What is blood pressure?
Blood pressure is the pressure created in the blood vessels by each heart beat.
When the heart contracts (= systole) and pumps blood into the arteries, it brings
about a rise in pressure. The highest value is known as the systolic pressure and
is the first value to be measured. When the cardiac muscle relaxes to take in fresh
blood, the pressure in the arteries also falls. Once the arteries are relaxed, a
second reading is taken – the diastolic pressure.

). Up to 60 measured values with date and time can be stored in each memory

Common factors of wrong measurement
• Please keep quiet for 5-10 minutes and avoid
eating, drinking alcohol, smoking, exercising
and bathing before taking measurement.

result.
• Remove any garment that fits closely to your
upper arm.
• Always measure on the same arm (normally left).
• T
every day
the day
• All efforts by the patient to support their arm can
increase blood pressure.
• Make sure you are in a comfortable, relax position
and do not activate any of the muscles in the
measurement arm during measurement. Use a
cushion for support if necessary
• If the arm artery lies lower or higher than the
heart, a false reading will be obtained.
• A
• With repeated measurements , blood accumulates
in the arm which can lead to false reading.
Consecutive blood pressure measurements should
be repeated after 1 minute pause or after the
arm has been held up in order to allow the
accumulated blood to flow away
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.

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 5-10 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.

Blood pressure that is too low represents just as great a health
risk as blood pressure that is too high! Fits of dizziness may lead
to dangerous situations arising (e.g. on stairs or in traffic)!
How is blood pressure measured?
The MEDISANA is a blood pressure unit which is used to measure blood
pressure at the upper arm. The measurement is carried out by a microprocessor
which, via a pressure sensor
and deflation of the cuff over the artery
