USAGE

General information about blood pressure

• Blood pressure is always stated in the form of two values:
• The highest pressure is systolic blood pressure. This arises when the heart muscle contracts and blood is pumped into the blood vessels.
• The lowest pressure is diastolic blood pressure. This arises 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.

Attaching the cuff

• Fundamentally, blood pressure can be measured on both wrists. Certain deviations between the measured blood pressure on the right wrist and left wrist are due to physiological causes and completely normal. You should always perform the measurement on the wrist 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 wrist.
• The device may only be operated with the cuff attached when supplied. Before using the device, the user should check the fit of the cuff and, in doing so, ensure that their wrist circumference is within the range printed on the cuff.
• Uncover your wrist. Ensure that the circulation of the wrist is not hindered by tight clothing or similar.
• Now place the cuff on the wrist so that the palm of your hand and the device display are facing upwards .
• Position the cuff so that there is a distance of 1.0 – 1.5 cm between it and the heel of your hand .
• Now fasten the cuff tightly around your wrist using the hook-and-loop fastener. Make sure that it is tight but that it does not cut into your wrist .

Adopting the correct posture

• To carry out a blood pressure measurement, make sure you are sitting upright and comfortably. Lean back so your back is supported.
• Place your arm on a surface.
• 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 speak.

Position indicator
As an additional application aid, the device has a position indicator built into the START/STOP button . This is intended to help you determine the correct measuring position of the device at heart level and depends on the angle of observation.

Display	Interpretation
Position indicator is colored red .	You have not yet reached the recommended position of the measuring device at heart level – your wrist is either positioned too high or too low.
Position indicator is colored green; the word "OK" also appears .	You have reached the recommended position of the measuring device at heart level and can start the measurement by pressing the START/STOP button .

In the vast majority of use cases, the position indicator provides an excellent guide as to whether the measuring device is at heart level. Due to physical differences such as size and/ or physique on the user side, this function may not be helpful in all cases. If you feel that the wrist position according to the position indicator does not match the level of the heart, use your own judgment. You can also start the measurement in these cases at any time by pressing the START/STOP button .

Selecting the user
This device has 2 user memories with 120 memory spaces each in order that you can save measurements from 2 different people separately from each other. If multiple people are using the device, make sure that the relevant user is set before each measurement. Please refer to the section "Adjusting the settings" for information on how to select the desired user.

Performing the blood pressure measurement
Measurement
Press the START/STOP button to start the blood pressure monitor. All display elements are briefly displayed.

• The blood pressure monitor will begin the measurement automatically after approx. 3 seconds.
• The cuff inflates automatically while the actual measurement process starts. As soon as a pulse is found, the pulse symbol is displayed.
  You can cancel the measurement at any time by pressing the START/STOP button .
• The remaining air is released quickly once the measurement is complete.
• Systolic pressure, diastolic pressure and pulse measurements are displayed. A symbol in the display also appears which shows you whether you were sufficiently relaxed during the blood pressure measurement or not ( symbol = sufficiently at rest; symbol = not at rest). Observe the chapter on evaluating results/resting indicator measurement in these instructions for use.
• Press the START/STOP button to switch off the blood pressure monitor. The measurement is then stored in the selected user memory.
• appears if the measurement could not be performed properly. In this case, please read the section "What if 1 there are problems?".

• If the Bluetooth^® function has been activated, the data transfer to the "beurer HealthManager Pro" app starts automatically after the measurement.
• 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 a connection is established. All measurement data is transferred to the apps. Once the data transfer is successfully complete, the device switches off automatically.
• If a connection to the smartphone cannot be established after 30 seconds, the Bluetooth® symbol goes out and the device switches off automatically after 1 minute.
• 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.

Transfer of measurements via Bluetooth®
In addition to displaying and saving your measurements locally on the device, you have the option of transferring your measurements to your smartphone using Bluetooth® low energy technology.
For this, you will need the "beurer HealthManager Pro" app. These apps are available for free in the Apple App Store and from Google Play.

System requirements:

• iOS ≥ 12.0 / Android™ ≥ 8.0
• Bluetooth® ≥ 4.0

List of compatible devices:

To transfer the measured values, proceed as follows:

1. BC 87
   Activate the Bluetooth® function on your device as described in the "Adjusting the settings" section.
   
2. "beurer HealthManager Pro" app
   In the "beurer HealthManager Pro" app, add the BC 87 under Settings / Devices and follow the instructions.
   
3. BC 87
   Take a measurement.
   

4. BC 87 (Data transfer immediately following the measurement):
   If the Bluetooth® function is activated, data will be automatically transferred after the measurement.
   BC 87
   (Data transfer at a later point):
   Go into the memory recall mode for the desired user memory (see "Saving, accessing and deleting measured values"). The data transfer starts automatically.

Also note the following information:

• When connecting for the first time, a randomly generated six-digit PIN code is displayed on the device, and at the same time an input field appears on the smartphone in which you must enter this six-digit PIN code. After successfully entering the code, the device will be connected to your smartphone.
• Ensure that the "beurer HealthManager Pro" app on your smartphone is always activated and launched when you start the data transfer on the device.
• You can tell that the data transfer is in progress by the Bluetooth® symbol shown on the display.
• If your smartphone has a protective cover, remove it to ensure that there is no interference during the transfer.

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.

Risk indicator
The World Health Organization (WHO) has defined the internationally recognized classification for the evaluation of measured blood pressure values listed in the table below:

Source: WHO, 1999 (World Health Organization)
The risk indicator (the arrow in the display and the associated scale on the device) shows which category the recorded blood pressure values fall into. If the measured values are in two different classifications (e.g. systole in the high normal category and diastole in the normal category), the risk indicator then always shows you the higher category – "high normal" in the example described.
Please be aware that these standard values can only serve as a general guideline, as the individual blood pressure varies in different people and different age groups, etc. Furthermore, it must be noted that measurements taken yourself while at home are generally lower than those that are taken by the doctor. For this reason, it is important that you regularly consult your doctor for advice. Only they are able to give you your personal target values for controlled blood pressure – in particular if you receive medicinal therapy.

Irregular heartbeat
This device can identify any irregular heartbeat disturbances as part of the analysis of your recorded pulse signal during blood pressure measurement. In this case, after the measurement, the device will indicate any irregularities in your pulse by displaying the symbol in the display. This can be an indicator for irregular heartbeat.
If the symbol appears on the display after the measurement, the measurement must be repeated as the measurement accuracy may be impaired. To assess your blood pressure, only use the results that have been recorded without corresponding irregularities in your pulse. If the symbol appears frequently, please consult your doctor. Only they can establish the existence of an arrhythmia during a checkup, using their means of diagnosis.

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 hemodynamic stability diagnostics (HSD) to measure the user's hemodynamic 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.

	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.
	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 minutes.
No resting indicator symbol is displayed	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 minutes.

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 irregular heartbeat 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 irregular heartbeat 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.

Saving, accessing and deleting measured values
User memory
The results of every successful measurement are stored together with the date and time. The oldest measurement is overwritten in the event of more than 120 measurements.

• To select the relevant user memory, press the memory buttonM1 (for user ) or M2 (for user memory ) when the device is switched off. Then confirm your selection by pressing the START/STOP button .
• If Bluetooth^® is activated (the symbol flashes on the display), the blood pressure monitor attempts to connect to the app. The buttons are deactivated and the symbol ceases to flash as soon as a connection is established and the data is transferred.

If you press the M1 or M2 memory button during this process, the transfer is canceled. The symbol is no longer shown.
