Intended use

Intended use
The blood pressure monitor is intended for the fully automatic, non-invasive measurement of arterial blood pressure and pulse values on the upper arm.

Target group
It is designed for self-measurement by adults in the home environment and is suitable for users whose upper arm circumference is within the range printed on the cuff. The device is also ideal for taking blood pressure measurements on women who are pregnant. This was successfully tested as part of a clinical study (Tempestas, Institut für Medizinische Forschung, Cloppenburg, Germany).

Indication/clinical benefits
The user can record their blood pressure and pulse values quickly and easily using the device. The recorded values are classified according to internationally applicable guidelines and evaluated graphically. Furthermore, the device can detect any irregular heart beats that occur during measurement and inform the user via a symbol in the display. The device saves the recorded measurements and can also output average values of previous measurements. 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 whether the measured blood pressure thus corresponds to your blood pressure when at rest. Read more about this under "Resting indicator" in the section on using the device. The recorded data can provide healthcare service providers with support during the diagnosis and treatment of blood pressure problems, and therefore plays a part in the long-term monitoring of the user's health.

Initial use

Inserting the batteries

• Remove the battery compartment lid on the rear of the device.
• Insert four 1.5 V AAA (alkaline type LR03) batteries. Make sure that the batteries are inserted the correct way round.
  
• Close the battery compartment lid again carefully.
• All display elements are briefly displayed, flashes in the display. Set the date and time as described below.

If the battery replacement symbol is permanently displayed, you can no longer perform any measurements and must replace all batteries. Once the batteries have been removed from the device, the date and time must be set again. Any saved measurements are retained.

Operation with the mains part

You can alternatively also operate this device with a mains part (not included in delivery). However, before connecting the device with the mains part, please ensure that you have removed the batteries from the device. During mains operation, there must not be any batteries in the battery compartment, as this could damage the device.

• To avoid any potential damage, the device may only be operated with a mains part that meets the specifications described in the chapter "Technical specifications".
• Furthermore, the mains part must only be connected to the mains voltage that is specified on the type plate.
• First, remove the protective cap of the mains part connector – located on the rear of the device – and insert the mains part into the connection intended for this purpose.
• 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 measured values are retained.

Set the hour format, date, time and Bluetooth^® settings

Usage

General rules when measuring blood pressure yourself

• In order to generate as informative a profile of the progres-sion of your blood pressure as possible and ensure that the measured values can be compared, you should measure your blood pressure regularly and always at the same times of day.
  It is recommended that you measure your blood pressure twice a day: once in the morning after getting up and once in the evening.
• You should always carry out the measurement when you are sufficiently physically rested. You should therefore avoid taking measurements during stressful periods.
• 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 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.

Attaching the cuff

• Fundamentally, blood pressure can be measured on both arms. Certain deviations between the measured blood pressure on the right arm and left arm are due to physiological causes and completely normal. You should always perform the measurement on the arm with the highest blood pressure values. Before starting self-measurement, consult your doctor in this regard. From this point on, always take measurements on the same arm.
• The device may only be operated with one of the following cuffs. This should be selected in accordance with your upper arm circumference. The fit should be checked before measurement using the index mark described below.

  Ref. no.	Designation	Arm circumference
  163.764*	Universal cuff	24-40 cm

  * Included in standard delivery
• Place the cuff onto 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 here.
  
• Guide the end of the cuff that is sticking out through the metal ring, fold it back over the arm and close the cuff using the hook-and-loop fastener. The cuff should be fastened tightly, but not too tightly, so that two fingers can still fit under the closed cuff.
  
• The cuff is suitable for you if the index mark () is within the OK range after fitting the cuff.
  
• Now insert the cuff line into the connection for the cuff connector.
  

Adopting the correct posture

• To carry out a blood pressure measurement, make sure you are sitting upright and comfortably. Lean back and place your arm on a surface. Do not cross your legs. Place your feet next to each other flat on the floor.
  
• Always make sure that the cuff is at heart level.
• To avoid distorting the measurement, you should remain as still as possible during the measurement and not speak.

Performing the blood pressure measurement

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 approx. 3 seconds. The cuff inflates as the first step.
  Measuring can be cancelled at any time by pressing the Start/stop button .
• Then the air pressure in the cuff is slowly released. Now the measurement starts. As soon as a pulse is found, the pulse symbol is displayed.
• If a tendency towards high blood pressure can already be identified, it is possible that the cuff may inflate again to a higher pressure level whilst the air is being released.
• The remaining air is released quickly once the measurement is complete.
• Systolic pressure, diastolic pressure and pulse measurements are displayed. On the display, the resting indicator lights up green or red depending on the assessment of your haemodynamic stability.
  
• appears if the measurement could not be performed properly. In this case, please read the section "What if there are problems?".
  
• 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.
• If the Bluetooth^® function has been activated, the data transfer to the "beurer HealthManager" app starts after confirming the user selection using the START/STOP button.
• The Bluetooth^® symbol flashes on the display. The device now attempts to connect to the app for approx. 30 seconds.
• The Bluetooth^® symbol stops flashing as soon as the connection is established. All measurement data is transferred to the app. Once the data transfer is successfully complete, the device switches off automatically.
• If a connection to the app cannot be established after 30 seconds, the Bluetooth^® symbol goes out and the device switches off automatically after 3 minutes.
• If you forget to turn off the device, it will switch off automatically after approx. 3 minutes. In this case too, the value is stored in the selected or most recently used user memory.

• After 30 seconds of not being in use or if communication with the PC is interrupted, the blood pressure monitor switches itself off automatically.

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 in the cycle is called systolic blood pressure. This arises when the heart muscle contracts and blood is pumped into the blood vessels.
  • The lowest is diastolic blood pressure, which is when the heart muscle has completely stretched back out and the heart fills with blood.
• Fluctuations in blood pressure are normal. Even during repeat measurements, considerable differences between the measured values may occur. 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
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 bar chart 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.

Resting indicator
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 correspond to 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.

Resting indicator lights up GREEN	The measured blood pressure value was obtained when the user's circulatory system was sufficiently at rest and reliably corresponds to the blood pressure at rest.
Resting indicator lights up RED	Indicates that the value was obtained when the user's circulatory system was not sufficiently at rest. The blood pressure values measured in this case generally do not correspond to the blood pressure at rest. The measurement should therefore be repeated after a period of physical and mental rest lasting at least 5 mins.
Resting indicator does not light up	During the measurement it was not possible to determine whether the user's circulatory system was sufficiently at rest. In this case too, the measurement should be repeated after a period of rest lasting at least 5 mins.

If the user's circulatory system was not sufficiently at rest, this can be caused by various factors such as physical or mental strain or distraction, speaking, or experiencing cardiac arrhythmia during the measurement.
In an overwhelming number of cases, HSD will give a very good guide as to whether the user's circulatory system is rested when taking a blood pressure measurement.
However, certain patients suffering from cardiac arrhythmia or chronic mental conditions may remain haemodynamically unstable even in the long-term, something which persists even after repeated periods of rest. The accuracy of the results for the blood pressure at rest is reduced in these users.
Like any medical measurement method, the precision of HSD is limited and can lead to incorrect results in some cases. Nevertheless, the blood pressure measurements taken when the user's circulatory system is sufficiently at rest represent particularly reliable results.
