Before the Blood Pressure Measurement

General Rules When Measuring Your Own Blood Pressure

• In order to generate an informative profile of changes in your blood pressure that can be used for comparisons, you should measure your blood pressure regularly and always at the same time of day. Measure your blood pressure twice a day: once in the morning after getting up and once in the evening.
• Always perform the measurement when you are sufficiently physically rested. Avoid taking measurements at stressful times.
• Do not measure within 30 minutes of eating, drinking, smoking or exercising.
• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes.
• If you want to take several measurements in succession, always make sure that you leave 5 minutes between each measurement.
• Repeat the measurement if you have doubts about the measured value.

Attaching the Cuff

You can measure your blood pressure on either arm. Some deviations between the values in the right and left arm are perfectly normal. Always measure the arm with the higher blood pressure values. Consult your doctor about this before starting self-measurement.

Always measure your blood pressure on the same arm.

• Only use the device with the cuff supplied, based on your upper arm circumference.
• Before taking the measurement, check the fit using the index mark described below.
• Expose your upper arm. The circulation of the arm must not be hindered by tight clothing or similar.
• The cuff must be placed on the upper arm so that the bottom edge is positioned 2–3 cm above the elbow and over the artery. The line should point to the centre of the palm (B).
• The cuff should be fastened so that two fingers fit under the cuff when it is closed (C).
• Now insert the cuff line into the connection for the cuff connector.
• The cuff is suitable for you if the index mark is within the OK range after fitting the cuff.

Adopting the Correct Posture

• Sit in a comfortable upright position when taking the blood pressure measurement. Lean back so that your back is supported.
• Place your arm on a surface (D).
• Place your feet flat on the ground next to one another.
• The cuff must be level with your heart.
• Stay as still as possible during the measurement and do not talk.

Taking a Blood Pressure Measurement

Requirement: Cuff attached.

Measurement

1. Press the START/STOP button. All display elements are briefly displayed. The cuff inflates itself automatically. The measurement process starts. The pulse symbol is displayed as soon as a pulse is detected. To cancel the measurement, press the START/STOP button.
2. The systolic pressure, diastolic pressure and pulse measurements are displayed.

The cuff position control symbol is displayed throughout the entire measurement. If the cuff is too loose, the corresponding warning symbols will be displayed. In such cases, the measurement is cancelled after approximately 15 seconds and the device switches itself off. An error indicator is displayed if the measurement could not be performed properly. In this case, please refer to the "Troubleshooting" section. If necessary, re-attach the cuff after 1 minute. The device switches off automatically after approximately 1 minute.

Evaluating the Results

General Information About Blood Pressure

• Blood pressure is the force with which the bloodstream presses against the arterial walls. Arterial blood pressure constantly changes in the course of a cardiac cycle.

Blood pressure is always stated in the form of two values:

• The highest pressure is the systolic blood pressure. This occurs when the heart muscle contracts and blood is pumped into the blood vessels.
• The lowest pressure is the diastolic blood pressure. This occurs when the heart muscle has completely relaxed again and the heart is filling with blood.

Fluctuations in blood pressure are normal. Even during repeat measurements, there may be considerable differences between the measured values. One-off or irregular measurements therefore do not provide reliable information about the actual blood pressure. Reliable assessment is only possible when you perform the measurement regularly under comparable conditions.

Cardiac Arrhythmia

The device can identify heart rhythm abnormalities during the blood pressure measurement. If the cardiac arrhythmia symbol is displayed after the measurement, this indicates that an irregularity has been detected in your pulse. Repeat the measurement if the cardiac arrhythmia symbol is displayed. When assessing your blood pressure, only use the results that have been recorded without any irregularities in your pulse. Consult your doctor if the cardiac arrhythmia symbol is displayed frequently. Only they can determine, through an examination, whether there is an abnormality.

Risk Indicator

Low Blood Pressure

WARNING

Low blood pressure (hypotension) can be a health hazard and cause dizziness or fainting. Blood pressure is considered low if systolic pressure is below 90 mmHg or diastolic pressure is below 60 mmHg (source: National Health Service, 2023). Seek medical attention if you suddenly suffer from low blood pressure.

Resting Indicator (Using HSD Diagnostics)

One of the most common errors made when taking a blood pressure measurement is not ensuring that the user's circulatory system is sufficiently at rest when taking the measurement. In this case, the measured systolic and diastolic blood pressure values do not represent the blood pressure at rest. However, it is this blood pressure at rest that should be used to assess the measured values. This blood pressure monitor uses integrated haemodynamic stability diagnostics (HSD) to measure the user's haemodynamic stability when taking the blood pressure measurement. This enables it to indicate whether the blood pressure was taken when the user's circulatory system was sufficiently at rest.

CLEANING AND MAINTENANCE

• Clean the device and cuff carefully using only a slightly damp cloth.
• Do not use any cleaning solutions or solvents.
• Under no circumstances hold the device or cuff under water, as this can cause liquid to enter and damage the device and cuff.
• If you store the device and cuff, do not place heavy objects on the device and cuff. The cuff line should not be bent sharply.
• Remove the batteries if the device is not going to be used for a long period of time.
