PURPOSE OF USE

This digital blood pressure monitor is intended for fully automatic blood pressure measurement on the arm of an adult person and is suitable for household use. Together with blood pressure, it also measures the pulse rate.
This digital blood pressure monitor utilises an oscillometric blood pressure measurement method. This means that it detects the movement of blood through the brachial artery and converts this movement into a digital value.
The inflation and deflation of the cuff is performed automatically and does not require any action from the user.

Note: Prior to first use of the device, carefully read this user’s manual because the correct measurement of blood pressure is only possible when the device is operated correctly.

WHAT YOU SHOULD KNOW ABOUT BLOOD PRESSURE

WHAT IS BLOOD PRESSURE?

Blood pressure is defined as the pressure exerted by the blood on the walls of the arteries through which it flows. Blood pressure fluctuates during the course of each heartbeat between the maximum (systolic) and the minimum (diastolic) value. Blood pressure is influenced by many factors, such as physical activity, fear, anger or by a certain time of day.
Blood pressure changes constantly over the course day. Early in the morning it rises and before noon it falls. In the afternoon it rises again and then falls in the evening hours. Blood pressure may also change within an instant and so the subsequent measurement results may vary.

WHY IS IT IMPORTANT TO MEASURE YOUR BLOOD PRESSURE AT HOME?

The difference between the blood pressure measurement at home and in the hospital is approximately 20–30 mmHg (2.7 kPa – 4.0 kPa). This is the result of the fact that people are usually more relaxed at home than at the hospital. This is the so-called white coat syndrome and may affect up to 15 % of the population.
Home blood pressure measurement eliminates the white coat syndrome and provides the doctor with a picture of the various blood pressure levels during your natural activity.

BLOOD PRESSURE CLASSIFICATION

To determine blood pressure, it is necessary to measure two values:
- Systolic (top) blood pressure: This is the value that is generated at the moment when the heart muscle contracts and blood is pumped into blood vessels.
- Diastolic (bottom) blood pressure: This is the value that is generated when the heart muscle is expanded and is again filling up with blood.
The measured heart pressure values are designated in millimetres of mercury (mmHg).
The following table shows the blood pressure classification for an adult person according to the World Health Organisation (WHO).

Blood pressure category

| Systolic blood pressure (mmHg)| Diastolic blood pressure (mmHg)
---|---|---
Optimal| <120| <80
Standard| 120–129| 80–84
High normal| 130–139| 85–89
Hypertension: Stage 1 (mild)| 140–159| 90–99
Hypertension: Stage 2 (medium)| 160–179| 100–109
Hypertension: Stage 3 (heavy)| ≥180| ≥110
Isolated systolic hypertension| ≥140| <90

WHAT IS HYPERTENSION

Hypertension (high blood pressure) is a serious illness that may negatively affect the quality of life. It may lead to a large number of health problems such as heart failure, kidney failure or bleeding into the brain. Hypertension and associated illnesses can be treated well if identified in time. For this, it is necessary to maintain a healthy lifestyle and to regularly visit your medical doctor for check ups.

Note: Do not worry if you have measured an abnormal blood pressure values. Blood pressure can be better assessed individually after 2 or 3 measurements performed always at the same time of day over a longer time period. If your results are still abnormal, please consult your medical doctor.

WHAT IS CARDIAC ARRHYTHMIA?

Cardiac arrhythmias are a disorder of the rhythm of the heartbeat. They result from a varied creation or conduction of electrical impulses in the heart. Many cardiac arrhythmias are only temporary in nature.
Such types of arrhythmias are considered to be harmless and include the cases where the heart misses or adds a beat. This may be caused by strong emotions or exercise. However, there exist types of arrhythmia, which may be life threatening and require professional treatment. Symptoms of cardiac arrhythmia
Symptoms of cardiac arrhythmia: strong or accelerated beating of the heart, feeling of tiredness, vertigo, loss of consciousness, lack of breath and chest pain.
Symptoms of bradycardia (slowed down heart activity): feeling of tiredness, lack of breath, vertigo or dizziness.
Symptoms of tachycardia (accelerated heart activity): the heartbeat may be felt in the neck or as a beat in the chest with irregular speed, feeling of unease, weakness, lack of breath, dizziness, sweating and vertigo.

CAN CARDIAC ARRHYTHMIA BE TREATED?

Cardiac arrhythmia can to a certain extent be prevented by eliminating the stimuli (physical exertion, stress, smoking, consumption of alcohol, coffee or other beverages containing caffeine) affecting the nervous system. Many types of cardiac arrhythmias do not require treatment as they are naturally compensated by the immune system.
Other types of cardiac arrhythmias must be treated with medication (antiarrhythmic agents), defibrillator implants or pacemakers. The treatment method depends on the type of cardiac arrhythmia, age of the patient and their physical condition. In any case, diagnosis of heart arrhythmia always requires consultation with a medical doctor.

When the blood pressure monitor is turned off, press the button.
The icon of the first user will appear. Pressing again will show the icon of the second user.

BEFORE STARTING MEASUREMENT

Rules for achieving the most accurate measuring results

Always take measurements at the same time of day, ideally in the morning, at noon and in the evening under the same conditions or according to the recommendations of your doctor. Due to the fact that you can measure a wide range of various blood pressure values during the day, the individual and random measurements do not have any informative value. Only regular measurements taken at the same time of day, carried out over a longer period of time, enable the meaningful assessment of blood pressure values.
Remain still for at least 5 minutes prior to taking a measurement. Even work at a desk increases systolic blood pressure by 6 mmHg and diastolic blood pressure by 5 mmHg.
Do not drink coffee or tea or smoke at least 30-45 minutes prior to taking a measurement. Do not eat or drink for approximately one hour prior to taking a measurement.
Do not take a measurement if you feel a strong urge to go to the toilet.
A full urinary bladder can cause an increase in blood pressure of approx. 10 mmHg.
Wait at least 20 minutes after taking a hot shower or bath.
Do not perform measurements in an excessively cold environment.
Take the pressure measurement on a naked arm while sitting in the upright position. Do not move the arm to which the cuff is attached.
During measurement, sit calmly, relaxed and don’t talk. Talking increases values by approx. 6 – 7 mmHg.
Prior to taking another measurement, wait approximately 4–5 minutes to allow the pressure in your the blood vessels to fully relax.
Take the measurements regularly. Even if your values improve, you should continue to monitor them yourself.

Note: To prevent measurement inaccuracies caused by electromagnetic interference, do not use this device in the vicinity of mobile telephones or microwave ovens.

MEASUREMENT

ATTACHING THE CUFF

Prior to putting on the cuff, insert the air hose plug of the cuff into the socket on the device, see fig. D.
Do not mechanically constrict the air hose of the cuff, do not squeeze or bend it.
Remove all tight clothing from the arm before attaching the cuff.
Slide the hand into the cuff and move it to the upper arm. The Cuff should be located at the same level as your heart, which means that the bottom edge of the cuff is approximately 2 – 3 cm above the elbow pit, see fig. E.
Fastening the cuff The cuff must not be too loose or too tight. There must be sufficient space between the arm and the cuff to enable one finger to be inserted. The air hose must not be crossed and must lead along the inner side of the arm, forearm, going towards the palm.

SITTING CORRECTLY DURING MEASUREMENT

Sit down in a calm place at a table or another suitable surface If sitting in a chair, comfortably lean against the backrest.
Position your feet next to each other with their entire surface on the floor. Do not cross your legs.
Place your forearm with your palm facing upwards in a relaxed manner on to the surface of the table and check that the cuff and the air hose are in the correct location, see fig. F.

Note

Blood pressure can be measured both on the left and the right arm.
However, the measurement results from the left and right arm may differ, and for this reason it is necessary to perform repeated measurements always on the same arm.

MEASURING BLOOD PRESSURE

Always start the measurement process after attaching the cuff.
In the event that the device is also used by another person, check that your user profile is selected, see chapter SELECTING A USER.
Press the button. The display will momentarily show all the symbols and then 00 will appear.
The device will automatically pressurise the cuff. During the pressurisation process, the pulse rate is detected, which is indicated by the symbol on the display.
If the cuff is correctly fitted, the symbol will be displayed for the entire duration of measurement. If the symbol appears, it means that the cuff is too loose and it needs to be tightened. If the starts flashing, stop the measurement by pressing the button. Wait 4-5 minutes and then perform the measurement again.
After pressurisation, the pressure in the cuff is continuously released and the values of the systolic (SYS) and diastolic (DIA) pressure and pulse frequency are automatically determined. The values will be shown on the display.
If the symbol appears during measurement, it means that you have moved during the measurement and the measurement may not proceed correctly. If this happens, end the measurement process, wait 4-5 minutes and take the measurement again.

Attention

Do not move or talk during the entire time of the measurement.
If you feel unwell during the measurement process, immediately stop the measurement by pressing the button.

Note

If the symbol appears then the device has detected cardiac arrhythmia, see chapter WHAT IS CARDIAC ARRHYTHMIA?
If this symbol appears frequently, it may indicate a malfunction of the heart’s rhythm. If this happens contact your medical doctor.

MEMORY FUNCTION
• The values of each measurement are automatically saved for
the respective user. This device is able to save up to 99 sets of
measurements for each user. As soon as the memory capacity is full,
