of the patient or disturbances in blood pressure measurement.
lToo frequent measurements may cause trauma to the patient due to impaired
blood flow.
lWrapping the cuff on a wound may lead to a deterioration of its condition.
lApplication of the cuff on the treated arm may lead to injury as a result of
temporary obstruction of blood flow during pressure increase.
lDo not put on and inflate the cuff, on the side where the mastectomy procedure
has been performed.
lInflation of the cuff may cause temporary stoppage of equipment monitoring vital
functions used on the same arm.
lPressure measurement using the automatic device for measuring blood pressure
does not cause long-term impairment of the patient's circulation.
lThe device is not suitable for simultaneous operation with high-frequency
electrosurgical equipment (HF).
lThe displayed pulse rate is not suitable for controlling the operating frequency of a
pacemaker!
lIn the case of arrhythmias, the measurement made using the device should be
consulted with a doctor.
Thank you for buying the blood pressure and pulse monitor Istel Cardic-100BT. This model

electrical or electromagnetic fields (e.g., nearby cellular phones, microwave ovens).
Otherwise, there may be a temporary deterioration in the accuracy measurements.
2. IMPORTANT INFORMATION ON BLOOD PRESSURE AND ITS
MEASUREMENT
2.1. How is hypertension / hypotension developed?
The level of blood pressure is regulated in the brain, in the circulatory center and adapted
to the current conditions based on feedback involving the nervous system. To adjust the
blood pressure, the frequency and the strength of heart contractions and the diameter of
blood vessels (the degree of contraction of smooth muscle of blood vessel walls). The
level of blood pressure changes periodically in the cardiac cycle: during the contraction
the value is the highest (systolic) and at the end of the diastole the value is the lowest
(diastolic pressure). In order to prevent the development of dangerous diseases, the
blood pressure values should be correct.
2.2. What is the correct pressure value?
The value of blood pressure is too high if the diastolic pressure at rest is above 90 mmHg
or the systolic pressure is over 160 mmHg. In such a case, you should immediately
consult your doctor. Long-term persistence of pressure on such a level endangers human
health due to the increased damage to bloodvessels.
If systolic pressure is within the range of 140 to 160 mmHg or the diastolic pressure is
between 90 to 100 mmHg, consult your doctor. Subsequently, regular self-measurement
will be necessary.
In the case of values that are too low, that is the systolic pressure is below 100 mmHg or
the diastolic pressure falls below 60 mmHg, you should also consult your doctor. Even in
the case of pressure values in the normal range, it is recommended to perform regular
blood pressure self-measurements. This allows for detecting any changes in the value of
blood pressure at an early stage and respond accordingly. If the patient is undergoing
treatment for hypertension/hypotension, regular measurements should be taken at a
specific time of day and the results recorded, and then presented to the doctor.
Never use the obtained results to individually change dosage of medications
prescribed by your doctor.
Self-measurement means control and not diagnosis and treatment. Unusual
values should always be consulted with your doctor. You should under no
circumstances change the doses of medications prescribed by the doctor.

lIf the values of your blood pressure at rest are usually normal, but elevated during
stress, you may suffer from labile (latent) hypertension. If you suspect that this
might be possible, contact your doctor.
lCorrectly measured diastolic pressure above 120 mmHg requires immediate
medical treatment.

5. TAKING MEASUREMENTS
5.1. Before the measurement
lDirectly prior to measurement one should not: eat, smoke and avoid physical
effort because all these activities have an impact on measurement results. Prior to
measurement you should relax, sitting on a chair in a quiet environment for
approximately 10 minutes.
lMeasurements should always be taken on the same arm (normally left).
lTake measurements on a regular basis, every day at the same time, because blood
pressure varies throughout the day.
5.2. Most frequent errors
For blood pressure measurements to be comparable, the same measurement conditions
are necessary! (these conditions always include peaceful surroundings).
lAll the patient's efforts to support the arm may result in increased blood pressure.
Select a comfortable and relaxed position. During the measurement, do not stretch
any muscles of the arm on which the cuff is wrapped. If necessary, use a pillow as
a support.
lThe operation of the pressure monitor may be disturbed by extreme temperatures,
humidity and taking measurements at high altitudes.
lPay attention not to pinch or bend the tubes.
lA loosely fitting cuff will cause incorrect measurement results.
lIn the case of repeated measurements there is a build-up of blood in the arm,
leading to incorrect results. For this reason, the correct blood pressure
measurement should be carried out after a 5 minute break or after lifting the arm,
to facilitate the outflow of the accumulated blood (after at least 3 minutes).
5.3. Wrapping the cuff
1. Insert the tip of the air duct firmly in the opening on the left
side of the unit (air tube socket).
2. Insert the end of the cuff under the metal buckle, with the
velcro facing out.
3. Wrap the cuff approximately 2-3 cm above the elbow. For best
results, wrap the cuff on bare skin, at heart level.
4. The compression of arm caused by tucked up sleeve may
prevent accurate reading.
5. The cuff should be wrapped easily on the shoulder and the Velcro should fasten
easily.
6. After wrapping the cuff, make sure that there is sufficient space under the cuff to fit
a finger.
7. If the cuff does not fit on the arm, the accuracy of measurements may be incorrect.
The air hose should be placed
in the center of the arm
Palm facing up
2-3 cm

ISTEL Cardic-100 | 8
lDo not fold the cuff or the air tube.
lTo disconnect the cuff, remove the air tube plug from the device.
lMeasurement can be started only after wrapping the cuff properly.
lThe cuff must be replaced if there is a leak or when the cuff is not operating
properly.
lIn order to ensure the accuracy of readings, you should only use the cuff supplied
by the manufacturer.
5.4. Body posture during the measurement
Relax, rest the elbow on the table with palm facing
up; the cuff should be at heart level. Accuracy of
readings may be reduced if the cuff is not wrapped
properly. The arm should be at the same height as
the heart. If the arm is too low, the reading results
will be too high. If the arm is too high, the reading
results will be too low.
5.5. Measurement procedure
After wrapping the cuff properly, you can start taking the measurement.
a) Press the START/STOP button, all the elements will be displayed on the screen (FIG.
1), the cuff will start inflating. The increasing cuff pressure is displayed continuously.
b) When the appropriate pressure is reached, it starts to decrease slowly. When the
pulse is detected, the heart icon will start blinking on the screen (FIG. 2)
c) After completing the measurement, the values of systolic and diastolic pressure and
the pulse rate appear on the screen (FIG. 3)
Example (FIG. 3): Systolic pressure 126, diastolic pressure 75, Pulse rate 78
The results of the measurement will be displayed until the device is turned off. If no
button is pressed within 3 minutes, the unit will automatically turn off to save battery
power.
5.6 Finishing the measurement
To interrupt blood pressure measurement (e.g. if the patient is feeling unwell), you can
press the START/STOP button at any time. The device will automatically reduce the
pressure of the cuff.
The arm should be
positioned at the same
height as the heart.
