What You Should Know About Blood Pressure

What is Blood Pressure?

Blood pressure is the pressure exerted by blood on the walls of arteries. It fluctuates with each heartbeat between the maximum (systolic) and minimum (diastolic) values. Factors like physical activity, fear, anger, and time of day influence blood pressure. It changes constantly throughout the day, typically rising in the morning and falling in the evening. Subsequent measurements may vary.

Why is it Important to Measure Your Blood Pressure at Home?

Home measurements can differ from hospital readings by approximately 20-30 mmHg (2.7-4.0 kPa) due to relaxation. This "white coat syndrome" affects up to 15% of the population. Home measurement eliminates this effect and provides a more accurate picture of blood pressure during natural activity.

Blood Pressure Classification

Blood pressure is determined by two values: Systolic (heart contraction) and Diastolic (heart relaxation). Values are measured in millimeters of mercury (mmHg). The following table shows blood pressure classification for adults according to the World Health Organisation (WHO):

What is Hypertension

Hypertension (high blood pressure) is a serious condition that can negatively impact quality of life and lead to health problems like heart failure, kidney failure, or stroke. Early identification and treatment, combined with a healthy lifestyle and regular doctor visits, are crucial.

What is Cardiac Arrhythmia?

Cardiac arrhythmias are disorders of the heart rhythm caused by irregular electrical impulses. Some are temporary and harmless (e.g., skipped or extra beats due to emotions or exercise), while others can be life-threatening and require professional treatment.

Symptoms of Cardiac Arrhythmia:

• Strong or accelerated heartbeat, tiredness, vertigo, loss of consciousness, shortness of breath, chest pain.
• Bradycardia (slowed heart activity): tiredness, shortness of breath, vertigo or dizziness.
• Tachycardia (accelerated heart activity): noticeable heartbeat in the neck, irregular chest beats, unease, weakness, shortness of breath, dizziness, sweating, vertigo.

Can Cardiac Arrhythmia be Treated?

Arrhythmias can be partially prevented by eliminating stimuli like physical exertion, stress, smoking, alcohol, and caffeine. Many types resolve naturally. Others may require medication, defibrillators, or pacemakers. Treatment depends on the type, patient age, and condition. Diagnosis always requires a doctor's consultation.

Preparing for Use

Information About the Power Source

The device can be powered by 4 standard AAA (1.5 V) batteries or an optional 5 V DC power adapter with a USB-C connector (sold separately). The adapter must meet IEC 60601-1 requirements.

Inserting Batteries

Remove the battery compartment cover. Insert 4 AAA alkaline batteries, observing correct polarity. Close the cover.

⚠️ Attention: Incorrect battery polarity may prevent the device from functioning or cause it to heat up.

Do not mix used and new batteries, or batteries of different types (e.g., alkaline and rechargeable). Remove batteries if the device will not be used for an extended period. Dispose of used batteries responsibly according to local recycling codes; do not throw them in fire.

? Note: Replace batteries when the display is dim, hard to read, does not turn on, or the ? symbol appears.

Setting the Date and Time

Correct date and time settings are essential for accurate record-keeping. With the device off, press and hold the On/Off button for approximately 3 seconds to enter setting mode. The year will flash. Use the On/Off button to set the year and confirm with the On/Off button. Repeat for month, hours, and minutes. Pressing the On/Off button saves the settings and moves to the next item.

Setting the Sound

After setting the date and time, the speaker symbol appears. Use the On/Off button to select sound ON or OFF. Press the On/Off button to confirm.

Setting the Units

The device can display blood pressure in mmHg or kPa. To enter unit setting mode, press and hold the On/Off button for approximately 5 seconds when the device is off. Press the On/Off button to toggle between mmHg and kPa. Press the On/Off button to save your selection.

Selecting a User

The monitor supports two users. Before each measurement, select the correct user by pressing the On/Off button when the device is off. Pressing the On/Off button again cycles between user icons (e.g., User 1, User 2).

Before Starting Measurement

Rules for Achieving the Most Accurate Measuring Results

• Take measurements at the same time of day, under the same conditions, or as advised by your doctor. Regular measurements over time provide meaningful assessment.
• Remain still for at least 5 minutes before measuring. Even sitting at a desk can affect readings.
• Avoid coffee, tea, smoking, eating, or drinking for at least 30-45 minutes before measurement.
• Do not take a measurement if you have a strong urge to urinate; a full bladder can increase blood pressure by approx. 10 mmHg.
• Wait at least 20 minutes after a hot shower or bath.
• Do not measure in excessively cold environments.
• Take measurements on a bare arm while sitting upright. Do not move the arm with the cuff.
• Sit calmly, relaxed, and do not talk during measurement. Talking can increase values by 6-7 mmHg.
• Wait 4-5 minutes between measurements to allow blood vessels to relax.
• Take measurements regularly, even if values improve.

? Note: To prevent inaccuracies from electromagnetic interference, keep the device away from mobile phones or microwave ovens.

Measurement

Attaching the Cuff

1. Insert the air hose plug into the device socket (see Figure D).
2. Do not kink, squeeze, or bend the air hose.
3. Remove tight clothing from the arm.
4. Slide the arm into the cuff and position it on the upper arm. The bottom edge of the cuff should be approximately 2-3 cm above the elbow pit (see Figure E).
5. Fasten the cuff snugly but not too tightly; one finger should fit between the arm and cuff. Ensure the air hose runs along the inner side of the arm towards the palm.

Sitting Correctly During Measurement

1. Sit in a calm place at a table or suitable surface. Lean against the backrest if using a chair.
2. Place feet flat on the floor, do not cross legs.
3. Rest your forearm, palm up, on the table. Ensure the cuff and air hose are correctly positioned (see Figure F).

? Note: Measurements can differ between the left and right arm. Always use the same arm for consistent readings.

Measuring Blood Pressure

1. Start measurement after attaching the cuff.
2. If the ⚠️ symbol appears, you moved during measurement. End the process, wait 4-5 minutes, and repeat.
3. If the ❤️‍? symbol appears, the device detected cardiac arrhythmia. Frequent appearance may indicate a heart rhythm issue; consult your doctor.
4. If another user's profile is selected, check your user profile selection.
5. Press the On/Off button. The display will show all symbols momentarily, then '00'.
6. The device will automatically inflate the cuff. The pulse rate will be detected and shown with the ❤️ symbol.
7. If the ✅ symbol appears, the cuff is correctly fitted. If the ✅ symbol flashes, the cuff is too loose; tighten it. If the ❌ symbol appears, stop measurement, wait 4-5 minutes, and repeat.
8. After inflation, the cuff deflates automatically, and systolic (SYS), diastolic (DIA) pressure, and pulse frequency are displayed.

⚠️ Attention: Do not move or talk during measurement. If you feel unwell, press the On/Off button to stop immediately.

Memory Function

Measurements are automatically saved for each user, up to 99 sets. Old values are overwritten when the memory is full.

When the device is off, press the Memory button to view the average blood pressure of the last 2-3 measurements. Pressing the Memory button again shows the last measured value, and subsequent presses cycle through stored values.

Deleting Values from Memory

1. With the device off, press the On/Off button and select the user whose data you want to delete.
2. Press the Memory button, then the On/Off button to activate the display.
3. Press and hold the Memory button for approximately 3 seconds to delete all memory for that user. The display will show '70'.

Error Codes

If an error occurs, an error code will appear on the display:

Troubleshooting

If you encounter problems, consult the following table. Contact an authorized service center if issues persist.

⚠️ Attention: If blood pressure cannot be measured even after trying all solutions, contact the vendor. Do not attempt to disassemble or repair the device yourself.

Turning Off the Device

Press the On/Off button to turn off the device. It will also turn off automatically after 1 minute of inactivity. When disconnecting the air hose, pull on the plug, not the hose itself.
