Introduction

Dear Customer,

We are delighted that you have decided to purchase a boso blood pressure monitor. The boso brand is synonymous with optimum quality and precision and is also number 1 among professionals: 77% of all German doctors currently use boso blood pressure monitors. 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, "→" 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

If the monitor is used in medical practice (in accordance with the legislation governing the operation of medical devices), it should be calibrated at regular intervals (see page 64).

The boso Carat professional blood pressure monitor is suitable for patients of all ages with an upper arm circumference of be-tween 16 and 48 cm. The monitor is not suitable for neonatals.

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.

Blood pressure values

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

●Systolic (upper) blood pressure:

This is produced when the heart muscle contracts and blood is forced into the blood vessels.

●Diastolic (lower) blood pressure:

This is present when the heart muscle expands and fills with blood again.

Blood pressure measurement values are expressed in mmHg (mm of mercury).

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

Blood pressure values

Whether medical treatment is necessary depends not only on the blood pressure, but also on the patient's risk profile. Please contact your GP if one of the values (systole, diastole) consistently exceeds the cut-off point for high blood pressure.

Self-measurement of blood pressure often produces somewhat lower values at home than at the doctor's. The German Hypertension League has therefore defined lower cut-off values for home measurements:

Home measurement: 135/85 mmHg Measurement in the doctor's surgery: 140/90 mmHg

Starting up

The device must be installed and put into operation in accordance with the instructions in this manual.

Illustration 1

→Use only high quality leak-proof batteries of the correct specifications (see "Technical data" P. 61).

⚠️ Never mix old and new batteries or different makes.
⚠️ 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.

Starting up

The monitor has a battery status display (see P. 34)

Battery fully charged.

Battery partially charged.

Replace battery soon.

Flashing! No further measurements possible. Replace battery.

⚠️ Care for the environment

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.

⚠️ Change batteries only when the monitor is switched off!

The memory store is deleted if the batteries are removed for a prolonged period (more than 30 sec.)! The memory store is deleted immediately if the batteries are removed in measurement or store mode!

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 regular measurements are taken under comparable conditions.
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 58).

4. 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.

5. If you are pregnant, consult your doctor before using the monitor.
6. 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.
7. Always measure your blood pressure from the arm with the higher blood pressure values (where not required otherwise (see page 49)).

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 numbercircumference
CA01 22 – 32 cm 143-4	-766*
CA02 32 – 48 cm 143-4	-767*
CA03 16 – 22 cm 141-4	-772*

* supplied as 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).

Preparing to measure your blood pressure

Observe the following instructions when measuring your blood pressure:

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

Sit comfortably for the blood pressure measurement. Support your back and arms. Do not cross your legs. Place your feet flat on the floor.

Relax for 5 minutes before taking a measurement.

Do not move during the measurement.

Attaching the cuff

The measurement should be taken from the bare upper arm.

In the case of tightly fitting outer clothing, ensure that the blood supply to the arm is not cut off when the sleeve is rolled up (if necessary remove the article of clothing before taking 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

Marking Artery 2-3 cm

Illustration 3

⚠️ Do not attach the cuff over wounds as 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 though 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.

too low values correct values too high values Illustration 4

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.

Measuring your blood pressure

→Start the measurement with your start button

⚠️ 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 ready for use (see illustration 5).

Measuring your blood pressure

The pump starts to inflate the cuff.

The monitor has an intelligent automatic inflation system for gentle inflation to the correct cuff pressure.

The increasing cuff pressure is displayed.

When the required pressure is reached, the pump switches off and the air is released slowly from the cuff.

⚠️ Interrupting a measurement:

A measurement can be interrupted at any stage by pressing the start button; the cuff deflates automatically.

During the measurement phase the descending cuff pressure and the flashing ♥ symbol are displayed (see illustration 6).

Measurement display

After the end of the measurement, the in-built valve opens automatically and the cuff deflates rapidly.

The measured blood pressure values (systole, diastole, pulse) are displayed (see illustration 7).

126 mmHg 86 mmHg (♥) 89 PUL/min

Illustration 7

The measurement is stored automatically.

Invalid measurements with an "Err" message (see page 54) are not stored.

If the symbol “he” appears after the measurement, it is recommended that the measurement is repeated, holding the arm completely still. If the “he” 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.

Measurement display

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.

Allow at least two minutes between measurements.

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

Recalling the last recorded measurement

To recall the result of the last measurement, press the START-button for approx. 3 seconds, while the unit is switched off.

The result of the last measurement appears for approx. 3 seconds. Afterwards the unit switches off automatically (see illustration 8).

126 mmHg 86 mmHg 89 PUL/min

Illustration 8

→To start a new measurement, simply press „START“.

The monitor switches off automatically 5 seconds after the last measurement is displayed.

Changing batteries when the monitor is switched on can result in loss of data (see page 46. Change batteries only when the monitor is switched off).

Mains operation

The mains connection socket is located at the rear of the monitor. Where required, use only the boso power supply unit (order number 410-7-153). This power supply unit produces a rectified output of the correct polarity. Other commercially available power supply units can cause damage to the electronic components, which will invalidate the warranty. There is also a risk of fire with these other power supply units.

⚠️ If there are no batteries in the unit, the memory store is cleared when it is disconnected from the mains.

⚠️ If there are fully charged batteries in the unit, the memory store is not cleared when it is disconnected from the mains.

→Disconnecting from the mains:

With the monitor switched off, disconnect the plug from the unit first of all and then disconnect the power supply unit from the wall socket

Error messages

If any problems occur during the measurement, the display will show an error message instead of a blood pressure reading.

Meaning of error messages:

Cause of Err message: Troubleshooting:

Excessive variation in cuff pressure Hold arm still during measurement

No valid pulse readings Check position of cuff (see page 48) and repeat measurement.

Systole – diastole difference Check position of cuff (see page 48) too small: and repeat measurement

Systole – diastole ≤10 mmHg

Cause of Err CuF message:

Incorrectly inflated Cuff possibly too

Troubleshooting:

loose, attach cuff more firmly (see page 49)

Error messages

“♥” Display: Troubleshooting:

Repeat measurement recommended, holding the arm absolutely 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.

Calibration checks - Testing instructions

(for trained specialist staff only)

Calibration checks – every 2 years at the latest – must be performed by the following institutions or persons:

• Manufacturer
  – Trade measurements authorities
• Persons who fulfil the requirements of the legislation governing the operation of medical devices.

A) Function testing

Function testing of the monitor can only be carried out on a person or with a suitable simulator.

B) Testing of pressure circuit integrity and deviation of pressure display

Note:

a) When the pressure in measurement mode increases above 320 mmHg, the quick release valve is triggered and the pressure circuit opens. When the pressure in test mode increases above 320 mmHg, the measured value display flashes.
b) Remove the plug from the cuff tube for testing. Then attach the short connecting piece of the plug – previously inserted into the socket on the monitor – to the cuff tube and insert the long connecting piece of the plug into the monitor.

A pump ball must also be introduced into the pressure circuit.

Calibration checks - Testing instructions

(for trained specialist staff only)

Testing

1.) Remove batteries.
2.) Hold start button pressed down and insert batteries.
3.) Release start button.
The monitor is now ready for testing; the current pressure is displayed in the SYS, DIA and PULS fields. The start button is illuminated green.
4.) Perform test for deviation of pressure display and pressure circuit integrity (observe setting time for cuff – at least 30 seconds) in the usual manner.

5.) Switch off monitor by pressing the start button again and re-establish all original connections.

C) Safety seal

As a safeguard, the upper and lower parts of the housing can be joined with a safety seal. Alternatively, a hole drilled in the lower side of the monitor for the connecting screw for the housing can be sealed for safety.
