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)!
Inﬂuencing and evaluating readings
your blood pressure several times, then record and compare the
results. Do not draw
any conclusions from a single reading. i
our 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.
taking readings, remember that the daily values are inﬂuenced by se-
factors. Smoking, consumption of alcohol, drugs and physical exertion
inﬂuence the measured values in various ways.
Measure your blood
pressure before meals. i
taking readings, allow yourself at least 5-10 minutes rest. i
the systolic and diastolic readings seem unusual (too high or too low) on
occasions, despite correct use of the unit, please inform your doctor .

prevents you from taking readings.

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
a rise in pressure. The highest value is known as the systolic pressure
is the ﬁrst value to be measured. When the cardiac muscle relaxes to take
fresh blood, the pressure in the arteries also falls. Once the arteries are re-
laxed, a second reading is taken – the diastolic pressure.
How is blood pressure measured?
MEDISANA BU 514 is a blood pressure unit which is used to measure
pressure at the upper arm. The measurement is carried out by a micro-
, which, via a pressure sensor , measures the vibrations resulting from
the inﬂation and deﬂation of the cuff over the artery
