Beurer medical BM 55 Manual

Getting to know your instrument

Check that the packaging of the Beurer BM 55 blood pressure monitor has not been tampered with and make sure that all the required contents are present. Before use, ensure that there is no visible damage to the device or accessories and that all packaging material has been removed. If you have any doubts, do not use the device and contact your retailer or the specified Customer Services address.
The upper arm blood pressure monitor is used for non-invasive measurement and monitoring of adults' arterial blood pressure. You can use it to measure your blood pressure quickly and easily, storing the results and displaying the progression of readings together with the average.
A warning is issued for anyone suffering from cardiac arrhythmia.
The recorded values are classified and evaluated graphically. This blood pressure monitor also has a haemodynamic stability display, which is referred to as a resting indicator throughout these instructions for use. This shows whether you, and consequently your circulatory system, are sufficiently at rest when the blood pressure measurement is being taken and is therefore a more precise indicator of your resting blood pressure. Read more about this in chapter "Evaluating results".

You can also operate this device with a mains part.
When doing so, there must not be any batteries in the battery compartment. The mains part can be obtained from specialist retailers or from the service address using order number 071.60.

• To prevent possible damage to the device, the blood pressure monitor must only be used with the mains part described here.
• Insert the mains part into the connection provided for this purpose on the blood pressure monitor. The mains part must only be connected to the mains voltage that is specified on the type plate.
• Then insert the mains plug of the mains part into the mains socket.
• After using the blood pressure monitor, unplug the mains part from the mains socket first and then disconnect it from the blood pressure monitor. As soon as you unplug the mains part, the blood pressure monitor loses the date and time setting but the saved measurements are retained.

Measuring blood pressure

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

Positioning cuff

Fit the cuff round your bare left upper arm. Blood circulation in the arm should not be restricted by tight clothing or other objects.

The cuff should be placed on the upper arm so that the lower edge is 2 to 3 cm above the bend of the elbow and above the artery. The tube should be in line with the centre of the palm.

Now place the free end of the cuff snugly, but not too tightly, around the arm, and fix it with the hook and loop fastener. The cuff should be fitted tight enough to allow just two fingers to fit beneath the cuff. Insert the cuff tubing into the socket for the cuff attachment. Now insert the cuff line into the connection for the cuff connector.

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 22 to 36 cm. A larger cuff for upper-arm circumferences of 35 to 44 cm can be obtained from specialist retailers or from the service address using order number 163.387.

Correct posture

• Rest for approx. 5 minutes before each measurement. Otherwise there may be divergences.
• You can perform the measurement either sitting or lying down. Always make sure that the cuff is on a level with your heart.
• 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.

Performing the blood pressure measurement

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

• To start the blood pressure monitor, press the Start/stop button . All display elements are briefly displayed.
  

The blood pressure monitor will begin the measurement automatically after 3 seconds.
The cuff automatically inflates.
Measuring can be cancelled at any time by pressing the Start/stop button .
The cuff's air pressure is slowly released. If you already recognise a tendency for high blood pressure, you should reinflate the cuff and increase the cuff's pressure again. As soon as a pulse is found, the pulse symbol is displayed.

• Systolic pressure, diastolic pressure and pulse measurements are displayed.
  
• A symbol at the bottom of the display also lights up to indicate whether you were sufficiently relaxed during the blood pressure measurement (green symbol = sufficiently at rest; red symbol = not at rest).
  
  Observe the chapter on interpreting results/measuring the resting indicator in these instructions for use.
• appears if the measurement could not be 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 M1 or M2 memory buttons. If you do not select a user memory, the measurement is stored in the most recently used user memory. The relevant symbol or appears on the display.
• Using the Start/stop button , 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. one minute. In this case too, the value is stored in the selected or most recently used user memory.
• Wait at least 5 minutes before taking an-other measurement!
  

Evaluating results

Cardiac arrhythmia:
This instrument can identify possible cardiac arrhythmia disorders during measurement and if necessary indicates the measurement with the flashing icon .
This may be an indicator for arrhythmia. Arrhythmia is a condition where the heart rhythm is abnormal as a result of defects in the bioelectrical system controlling the heart beat. The symptoms (omitted or premature heart beats, slow or excessively fast heart rate) may be caused, among other things, by heart disease, age, physical predisposition, excessive use of stimulants, stress or lack of sleep. Arrhythmia can only be ascertained through examination by your doctor.
Repeat the measurement if the flashing icon is displayed after the measurement. Please note that you should rest for 5 minutes between measurements and not talk or move during the measurement. If the icon appears often, please contact your doctor. Any self-diagnosis and treatment based on the test results may be dangerous. It is vital to 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 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'.

Measuring the resting indicator (using the HSD diagnosis)

The most frequent error made when measuring blood pressure is taking the measurement when not at rest (haemodynamic stability), which means that both the systolic and the diastolic blood pressures are distorted.
While measuring the blood pressure, the device automatically determines whether you are at rest or not.
If there is no indication that your circulatory system is not sufficiently at rest, the symbol (haemodynamic stability) lights up green and the measurement can be recorded as a reliable resting blood pressure value.

GREEN: Haemodynamic stability

Measurement of the systolic and diastolic pressure is increased when the circulatory system is sufficiently at rest and is a very reliable indicator of resting blood pressure. However, if there is an indication that the circulatory system is not sufficiently at rest (haemodynamic instability), the symbol lights up red.
In this case, the measurement should be repeated after a period of physical and mental rest. The blood pressure measurement must be taken when the patient is physically and mentally rested, as it will be the basis for diagnosing the blood pressure level and regulating the patient's medical treatment.

RED: Lack of haemodynamic stability

It is very probable that the systolic and diastolic blood pressures have not been measured whilst the patient is at rest and the resting blood pressure measurement has therefore been distorted. Repeat the measurement after a rest and relaxation period of at least five minutes. Go to a sufficiently quiet and comfortable spot and remain there calmly; close your eyes, breathe deeply and evenly and try to relax.
If the next measurement also shows insufficient stability, you can repeat the measurement after another resting period. If the measurements continue to show some instability, identify these blood pressure measurements as having been taken when the circulatory system had not been sufficiently rested.
In this case, nervousness or inner anxiety may be the cause and this cannot be cured by brief periods of rest. Existing cardiac arrhythmias may also prevent a stable blood pressure measurement. A lack of resting blood pressure can have various causes, such as physical or mental strain or distraction, speaking or experiencing cardiac arrhythmias during the measurement.
In an overwhelming number of cases, the HSD diagnosis will give a very good guide as to whether the circulatory system is rested when taking the measurement. Certain patients suffering from cardiac arrhythmia or chronic mental conditions can remain haemodynamically unstable in the long-term, something which persists even after repeated periods of rest. The accuracy of the resting blood pressure results is reduced in these users. Like any medical measurement method, the precision of the HSD diagnosis is limited and can lead to incorrect results in some cases. The blood pressure measurements taken when the circulatory system was at rest represent particularly reliable results.
