Measuring blood pressure

Ensure the device is at room temperature before measuring. The measurement can be performed on the left or right arm.

Attaching the cuff

Place the cuff on to the bare 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.

Now tighten the free end of the cuff, but make sure that it is not too tight around the arm and close the hookand-loop fastener. The cuff should be fastened so that two fingers fit under the cuff.

Now insert the cuff line into the connection for the cuff connector.

This cuff is suitable for you if the index mark () is within the OK range after fitting the cuff on the upper arm.

If the measurement is performed on the right upper arm, the line should be located on the inside of your elbow. Ensure that your arm is not pressing on the line.
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.

The unit may only be operated with the original cuff. The cuff is suitable for an arm circumference of 23 to 43 cm.

Adopting the correct posture

• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes. Otherwise deviations can occur.
• You can take the measurement while sitting or lying down. Always make sure that the cuff is at heart level.
• To carry out a blood pressure measurement, 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.
• To avoid falsifying the measurement, it is important to remain still during the measurement and not to speak.

If a connection to the app cannot be established after 30 seconds, the Bluetooth^® symbol goes out and the blood pressure monitor switches off automatically after 1 minute.
Please note that you must add the blood pressure monitor in "My devices" in the "beurer HealthManager" app to enable data transfers. The "beurer HealthManager" app must be active to allow data transfers.
If the latest data is not displayed on your smartphone, repeat the data transfer as described in chapter "Display and delete measured values".

If you forget to turn off the blood pressure monitor, it will switch off automatically after a further 30 seconds. In this case too, the value is stored in the selected or most recent user memory and the data is transferred if Bluetooth^® data transfer has been activated.

• Wait for at least 1 minute 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 appears frequently, please consult your doctor. Only they are able to determine any arrythmia during an examination.

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 unit 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'.
