PURPOSE OF USE

• This digital blood pressure monitor is intended for fully automatic blood pressure measurement on the wrist 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 utilizes 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 millimeters of mercury (mmHg).
• The following table shows the blood pressure classification for an adult person according to the World Health Organization (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.

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

• Before putting on the cuff, remove all clothing and decorations from the arm in the location of the wrist.
• Slide the arm into the cuff. The palm must be turned upwards.
• Wind the cuff around the wrist and secure it in place. The cuff must not be too loose or too tight. Leave a gap of 10-15 mm between the edge of the wrist and the cuff, see fig. D.

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.
• Calmly place the forearm with the palm facing upwards on to the surface of a table so that the cuff is at the level of your heart. You may place an appropriate mat between your forearm and the table, e.g. a rolled up towel or pillow.
• Relax the wrist and the arm. Do not flex the wrist backwards or forwards and do not clench your fist.

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.

COLOUR DESIGNATION OF VALUES

Values of the measured blood pressure are shown on the display not only by means of numbers but also by means of the color of the values and symbols. The colors differs based on the measured pressure as follows:

Background colour|

Meaning

| Systolic pressure (mmHg)| Diastolic pressure (mmHg)
---|---|---|---
Red| High pressure| ≥ 160| ≥ 100
Yellow| Increased pressure| 140–159| 90–99
Green| Normal pressure| 90–139| 60–89
Yellow| Low pressure| < 90| < 60

TROUBLESHOOTING

In this chapter you will find solutions to problems that you may encounter when using this device. If you were unable to remedy the problem according to the following instructions, contact an authorized service center.

Replace the batteries.
Check that the positive and negative poles of the battery are not installed in reverse.| Install the batteries correctly.
Pressurization is not occurring.| Check that the cuff is not damaged.| Contact the vendor and request a new cuff.
The measurement did not occur, no value was displayed or improbable values were measured.| The arm was moved during the measurement.| Keep the arm and the whole body still.
Talking during measurement.| Do not talk while measuring blood pressure.
Air leaking out of the cuff| The cuff is fitted too tightly or is incorrectly located on the arm.| Check the fitting and location of the cuff.
The cuff is torn or otherwise damaged.| Contact the vendor and request a new cuff.
The blood pressurevalue that is measured at home is higher than the value measured at the doctor| The cuff may be incorrectly positioned on the arm. If this happens, no blood pressure value may be measured or the value may be much higher than it is in reality.| Check the fitting and location of the cuff.
The cuff is not fitted sufficiently firmly. If the cuff is loose, the compression force may not be transfer-

red to the artery, which will cause the blood pressure value to be much higher than it actually is.

You are not sitting correc- tly. You must not slouch, bend over, bend or sit with crossed legs or in a position where the arm with the cuff is located below the level of the heart.| Reacquaint yourself with the instructions and recommendations for correct seating provided in this user’s manual.
