Getting to know your device

Check that the packaging of the Beurer BC 21 blood pressure monitor has not been tampered with and make sure that all the required contents are present. The wrist blood pressure monitor is used to carry out non-invasive measurement and monitoring of arterial blood pressure values in human adults. This allows you to quickly and easily measure your blood pressure, save the measurements and display the development of the measurements. You are also warned of possible existing cardiac arrhythmia.
The recorded values are classified and evaluated graphically. The wrist blood pressure monitor also has voice output in five different languages (German, English, French, Italian and Turkish). The instructions and measurement results are announced to you in the selected language.

Important notes

Signs and symbols

The following symbols are used in these instructions for use, on the packaging and on the type plate for the device and the accessories:

Notes on use

• In order to ensure comparable values, always measure your blood pressure at the same time of day.
• Do not take a measurement within 30 minutes of eating, drinking, smoking or exercising.
• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes.
• Furthermore, if you want to take several measurements in succession, make sure always to wait for at least 1 minute between the individual measurements
• Repeat the measurement if you are unsure of the measured value.
• The measurements taken by you are for your information only – they are no substitute for a medical examination! Discuss the measured values with your doctor and never base any medical decisions on them (e.g. medicines and their dosages).
• Do not use the blood pressure monitor on newborns or patients with preeclampsia. Before using the blood pressure monitor during pregnancy, we recommend you consult with a doctor.
• Cardiovascular diseases may lead to incorrect measurements or have a detrimental effect on measurement accuracy. The same also applies to very low blood pressure, diabetes, circulatory disorders and arrhythmias as well as chills or shaking.
• In the case of restricted circulation on the arm as a result of chronic or acute vascular diseases (including vascular constriction), the accuracy of the wrist measurement is limited. In this case you should use an upper arm blood pressure monitor instead.
• This device is not intended for use by people (including children) with restricted physical, sensory or mental skills or a lack of experience and/or a lack of knowledge, unless they are supervised by a person who is responsible for their safety or are instructed by such a person in how to use the device.

Measuring blood pressure

Attaching the cuff

Blood pressure may vary between the right and left arm, which may mean that the measured blood pressure values are different. Always perform the measurement on the same arm. If the values between the two arms are significantly different, please consult your doctor to determine which arm should be used for the measurement. We generally recommend you carry out the measurement on the left wrist.

• Expose your left wrist. Ensure that the circulation of the arm is not hindered by tight clothing or similar.
  Place the cuff on the inside of your wrist.
  
• Close the cuff with the hook-and-loop fastener such that the upper edge of the device is positioned approx. 1 cm underneath the heel of the hand.
  
• The cuff must be fitted tightly around the wrist, but must not constrict.
  

Adopting the correct posture

• Before every measurement, relax for about 5 minutes. Otherwise deviations can occur.
• You can take the measurement while sitting or lying down. To take your blood pressure, make sure you are sitting comfortably with your arms and back leaning on something. Do not cross your legs. Place your feet flat on the ground. Make sure to support your arm and bend it. Always make sure that the device is at heart level during the measurement. Otherwise significant deviations can occur. Relax your arm and the palm of your hand.
  
• To avoid falsifying the measurement, it is important to remain still during the measurement and not to speak.

Measuring blood pressure

As described above, attach the cuff and adopt the posture in which you want to perform the measurement.

• Press the START/STOP button to start the blood pressure monitor. All displays will illuminate briefly.
  
• The last measured value is displayed and the blood pressure monitor automatically begins the measurement after 3 seconds.
  You can cancel the measurement at any time by pressing the START/STOP button .

As soon as a pulse is found, the pulse symbol be displayed.

• Systolic pressure, diastolic pressure and pulse readings are displayed.
  
• appears if the measurement has not been performed properly. Observe the chapter on error messages/troubleshooting in these instructions for use and repeat the measurement.
• Now select the desired user memory by pressing the memory button M. If you do not select a user memory, the measurement is stored in the most recently used user memory. The relevant or symbol appears on the display.
• Press the START/STOP button to switch off the blood pressure monitor. The measurement is then stored in the selected user memory.

If you forget to turn off the device, it will switch off automatically after approx. 1 minute.
In this case too, the value is stored in the selected or most recently used user memory.
Wait at least 1 minutes before taking another measurement!

Evaluating results

Cardiac arrhythmia

This device can identify potential disruptions of the heart rhythm when measuring and, if necessary, indicates this after the measurement with the symbol .
This can be an indicator for arrhythmia. Arrhythmia is an illness in which the heart rhythm is abnormal because of flaws in the bioelectrical system that regulates the heartbeat. The symptoms (skipped or premature heart beats, pulse being slow or too fast) can be caused by factors such as heart disease, age, physical make-up, excess stimulants, stress or lack of sleep. Arrhythmia can only be determined through an examination by your doctor.
If the symbol is shown on the display after the measurement has been taken, repeat the measurement. Please ensure that you rest for 5 minutes beforehand and do not speak or move during the measurement. If the symbol appears frequently, please consult your doctor. Self-diagnosis and treatment based on the measurements can be dangerous. Always follow your doctor's instructions.

Risk indicator

The measurements can be classified and evaluated in accordance with the following table.
However, these standard values serve only as a general guideline, as the individual blood pressure varies in different people and different age groups etc.
It is important to consult your doctor regularly for advice. Your doctor will tell you your individual values for normal blood pressure as well as the value above which your blood pressure is classified as dangerous. The classification on the display and the scale on the device show which category the recorded blood pressure values fall into. If the values of systole and diastole fall into two different categories (e.g. systole in the 'High normal' category and diastole in the 'Normal' category), the graphical classification on the device always shows the higher category; for the example given this would be 'High normal'.
