Blood pressure classification WHO
These values have been specified by the World Health Organisation (WHO)
without making any allowance for age.
Low blood pressure systolic <100 diastolic <60
Normal blood pressure (green display area )
systolic 100 - 139 diastolic 60 - 89
Forms of high blood pressure / hypertension
Mild hypertension (yellow display area )
systolic 140 – 159 diastolic 90 – 99
Moderate hypertension (orange display area )
systolic 160 – 179 diastolic 100 – 109
Severe hypertension (red display area )
systolic ≥ 180 diastolic ≥ 110
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
• Measure your blood pressure several times, then record and compare the
results. Do not draw any conclusions from a single reading. i
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. i
When taking readings, remember that the daily values are influenced by se-
veral factors. Smoking, consumption of alcohol, drugs and physical exertion
influence the measured values in various ways. i
Measure your blood pressure before meals. i
Before taking readings, allow yourself at least 5-10 minutes rest. i
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.
Starting up
Insert / replace batteries
You must insert the batteries provided before you can use your unit. The lid of
the battery compartment is located on the underside of the unit. Open it by
slightly pushing it and moving it upwards. Remove it and insert the 4 AA LR6
type 1.5V batteries supplied. Ensure correct polarity when inserting the batteries
(as marked inside the battery compartment). Close the battery compartment.

mation is lost and needs to be input again.
Fitting the cuff
Push the end piece of the air tube into the hole on the left side of the unit
prior to use. i
Slide the open end of the cuff through the metal bracket so that the Velcro
fastener is on the outside and it becomes a cylindrical form (Fig.1). Slide the
cuff over your left upper arm. i
Position the air hose in the middle of your arm in line with your middle finger
(Fig.2) (a). The lower edge of the cuff should be 2 - 3 cm above the crease of
the elbow. (b). Pull the cuff tight and close the Velcro fastener (c). i
Measure the pulse on your bare arm. i
Only position the cuff on the right arm if it cannot be used on the left arm. Al-
ways carry out measurements on the same arm. i
Correct measuring position for sitting (Fig.3).
Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any reason
(eg. the patient feels unwell) the START/STOP button can be pressed at
any time. The device immediately decrease the cuff pressure automatically.

Common factors of wrong measurements
• Please keep quiet for 5-10 minutes and avoid eating,
drinking alcohol, smoking, exercising and bathing
before taking a measurement. All these factors will
influence the measurement result.
Remove any garment that fits closely to your
upper arm.
Always measure on the same arm (normally left).
Measurements should be taken regularly at the
same time of each day, as the blood pressure varies
even during the day.
Any effort to support the arm during measurement
may increase the measured blood pressure.
Make sure, you are in a comfortable, relaxed posi-
tion and do not move or constrict your muscles
during measurement. Use a cushion to support your
arm if necessary.
If the arm artery lies lower or higher than the heart,
a false reading will be obtained.
A loose or open cuff causes false readings.
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.

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 re-
laxed, a second reading is taken – the diastolic pressure.
How is blood pressure measured?
The MEDISANA BU 514 is a blood pressure unit which is used to measure
blood pressure at the upper arm. The measurement is carried out by a micro-
processor, which, via a pressure sensor, measures the vibrations resulting from
the inflation and deflation of the cuff over the artery.
1. User setting:

automatically after approx. 180 seconds if no buttons are pressed. The unit
may also be switched off using the START/STOPbutton .
Do not take any therapeutic measures on the basis of a self
measurement. Never alter the dose of a medicine prescribed
by a doctor.
