Introduction

Dear Customer, We are delighted that you have decided to purchase a boso blood pressure monitor. The boso brand is synonymous with optimal quality and precision and is also number 1 among professionals: 96% of all German general practitioners, physicians and internists work in practice with blood pressure instruments from boso (API survey conducted by GfK 01/2016). The experience gained from decades of use by professionals has also been incorporated into all the patient monitors for home measurement. This instrument has also passed our strict quality control procedures and is your reliable partner for monitoring your blood pressure values.

Please read these user instructions before using the instrument for the first

time, as correct blood pressure readings can only be obtained if the instrument is operated correctly.

In these user instructions, _u^ = ^ means an action by the user.

To get help concerning usage or maintenance please contact your dealer or the manufacturer (contact details can be found on the back cover of this manual).

An unexpected operating condition or an incidence which has worsened the health condition or could have worsened the health condition should be reported to the manufacturer immediately.

If the instrument is to be sold, ensure that these user instructions are enclosed.

Introduction

Purpose

The boso-medicus vital blood pressure monitor is suitable for patients with an upper arm circumference of between 22 and 48~cm

The use of accessories not referred to in these instructions for use can undermine safety.

Wireless communication devices, such as home networking devices, mobile phones, cordless phones and their base stations, walkie-talkies can affect this blood pressure monitor. Therefore, a minimum distance of 11 feet should be kept from such devices.

Non-invasive recording of systolic and diastolic blood pressure and pulse rate in adults. Not suitable for use on newborn babies and infants. The device is suitable for self-measurement at home. The patient is regarded as the operator.

The instrument can be used with any a circumference as shown on the corresponding cuff.

Blood pressure values

To determine the blood pressure, two ues need to be measured:

vDiastolic (lower) blood pressure: Thisispresentwhentheheartmuscleexpands and fills with blood again.

Systolic (upper) blood pressure:

This is produced when the heart muscle blood pressure measurement values are contracts and blood is forced into the expressed in mmHg (mm of mercury). blood vessels.

The World Health Organization (WHO) has defined the following cut-off values for assessing blood pressure:
	systolic diastolic
High blood pressure (hypertension) over Borderline normal blood pressure 130 to Normal blood pressure 120 to 129 mmHg 80 to 84 mmHg Optimum blood pressure up to 119 mmHg	140 mmHg over 90 mmHg 139 mmHg 85 to 89 mmHg Hg 80 to 84 mmHg Hg up to 79 mmHg

Starting up

The device must be installed and put into! Never mix old and new batteries or operation in accordance with the instruc- different makes. tions in this manual.

Use only high quality leak-proof batteries of the correct specifications (see "Technical data" P. 75).

If the batteries are not inserted correctly, the monitor will not work and this may cause the batteries to heat up and leak, damaging the monitor.

Inserting the batteries

The battery compartment is located on the underside of the monitor.Insert batteries in the battery compartment as shown in illustration 1.

• Remove the batteries if the monitor is not to be used for any length of time.

Batteries that are short-circuited can become hot and cause burning.

Starting up

The monitor has a battery status display Care for the environment (see P. 46)

Battery fully charged.

Battery partially charged.

Replace battery soon.

Flashing! No further measurements possible. Replace battery.

Do not dispose of used batteries and charger units in domestic waste. You can take these to collection sites for used batteries or special waste. Contact your local authority for information.

General instructions for self-measurement

1. Fluctuations in blood pressure are quite normal. Even when measurements are repeated, there can be marked differences. Single or irregular measurements do not provide reliable information about the actual blood pressure. A reliable evaluation is only possible if reg-5. Uar measurements are taken under comparable conditions and themeasurement values entered in the blood pres-6. sure record card.

2. Self-testing does not mean self-treatment. Do not on any account change the dose of medicine prescribed by your doctor of your own accord.

3. Irregular heartbeats can affect the accuracy of the monitor or result in incorrect measurements (see page 71).

Incorrect measurements can also occur in patients with a weak pulse (possibly in patients wearing a pacemaker, for example). The blood pressure monitor itself has no effect on the pacemaker.

The device has not been validated for use on pregnant women.

Always take the measurement in a calm and relaxed state.

You are recommended to check your blood pressure twice a day—in the morning on getting up and in the evening once you have relaxed after work.

Always measure your blood pressure from the arm with the higher blood pressure values (where not required otherwise see page 60).

General instructions for self-measurement

To do this, measure the blood pressure first in both arms and thereafter always from the arm with the higher blood pressure.

Preparing to measure your blood pressure

Note on cuff sizes:

The monitor may only be used with the following cuff types. These should be chosen according to the upper arm circumference printed on them.

Type	Arm Order number circumference
CA01	22 - 32 cm 143-4-764
CA02	32 - 48 cm 143-4-757
CA04	22 - 42 cm 143-4-765*

• included in the standard.

Attach the cuff to the monitor by pressing the plug (click) into the socket on the left side of the unit. (See illustration 2).

Illustration 2

Preparing to measure your blood pressure

Observe the following instructions Attaching the cuff

when measuring your blood pressure.

The measurement should be taken from the bare upper arm.

Avoid smoking or drinking coff for one hour before measuring your blood pressure.

In the case of tightly fitting outer clothing, ensure that the blood supply to

legs. Place your feet flat on the floor.

Relax for 5 minutes before taking a measurement.

Do not move during the measurement.

Open out the cuff into the shape of a ring and slide it over the upper arm until the bottom edge of the cuff is about 2-3 cm above the elbow. The cuff must be positioned so that the marking is over the artery (see illustration 3).

Preparing to measure your blood pressure

Illustration 3

Do not attach the cuff over wounds this can cause further injuries.
Ensure that the cuff is not attached to an arm where arteries or veins are undergoing or have undergone medical treatment (e.g. shunt).
For women who have had a breast amputated, do not attach the cuff to the arm on the amputated side of the body.

During the measurement, medical apparatus that are being used on the same arm at the same time, may malfunction.
The cuff must not be too tight. There should be enough space to fit roughly two fingers between arm and cuff.
The metal ring should never lie over the artery (see illustration 3) as this may produce a false reading.

• Grasp the end of the cuff that feeds through the metal ring and wrap it around the outside of your arm. Attach the Velcro fastener by applying gentle pressure.

Preparing to measure your blood pressure

Place your arm with the cuff attached on the table, holding it relaxed and slightly bent so that the cuff is level with your heart.

Do not talk during the measurement.

Check that the air tube is not kinked during the measurement. This could cause congestion of the blood flow and subsequent injury.

The blood pressure measurement should not prevent the flow of blood for an unnecessary length of time (>2 minutes). If the monitor fails to function correctly, remove the cuff from the arm.
Excessive frequent measurements can cause injury by restricting blood flow.
The device may not be used by unsupervised children.
Do not use the device near infants. This can lead to accidents or damage.
Do not start the device without putting on the cuff.
There are small parts that may cause a choking hazard if swallowed by mistake by infants.

Preparing to measure your blood pressure

If the ambient temperature changes significantly, leave the device about an hour to adapt to the new ambient temperature before using it.

Now hold the arm absolutely still and do not talk.

All the items on the LCD display appear briefly to indicate that the monitor is now

The performance of the device can be affected by excessive temperature, humidity or altitude.

If the symbol appears after the measurement, it is recommended that the measurement is repeated, holding the arm completely still. If the symbol appears again even with the arm held still, this may be an indication of an irregular heartbeat. Please discuss this with your doctor at your next visit.

Illustration 7

Measurement display

The symbol indicates that the arm moved during measurement. You are advised to take another measurement.

Allow at least two minutes between measurements.

If no further measurement is required, remove the cuff from the arm.

Blood pressure is a dynamic parameter and can be affected by the patient's position, e.g. sitting, standing, lying, moving, before or during the measurement, physical condition (stress, disease, etc.).

If the measurement result is obviously wrong, repeat the measurement.

The unit switches itself off automatically after about 1 min. To repeat a measurement, press the start button again briefly.
