Introduction

Dear Customer,We are delighted that you have decidedto purchase a boso blood pressure mon-itor. The boso brand is synonymous withoptimal quality and precision and is alsonumber 1 among professionals: 77% ofall German doctors currently use bosoblood pressure monitors. The experiencegained from decades of use by profession-als has also been incorporated into allthe patient monitors for home measure-ment.This instrument has also passed our strictquality control procedures and is your reli-able partner for monitoring your bloodpressure values.

� Please read these user instructionsbefore using the instrument for the firsttime, as correct blood pressure readings

can only be obtained if the instrument isoperated correctly.In these user instructions, „➡“ means anaction by the user.

To get help concerning usage or mainten-ance please contact your dealer or themanufacturer (contact details can befound on the back cover of this manual).

An unexpected operating condition or anincidence which has worsened the healthcondition or could have worsened thehealth condition should be reported to themanufacturer immediately.

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

Introduction

If the monitor is used in medical practice(in accordance with the legislation govern-ing the operation of medical devices), itshould be calibrated at regular intervals(see page 62).

The boso medicus blood pressure monitoris suitable for patients of all ages with anupper arm circumference of be-tween 22and 48 cm. The monitor is not suitable forneonatals.

Wireless communication devices, such ashome networking devices, mobile phones,cordless phones and their base stations,walkie-talkies can affect this blood pres-sure monitor. Therefore, a minimumdistance of 11 feet should be kept fromsuch devices.

Blood pressure values

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

● Systolic (upper) blood pressure:This is produced when the heart musclecontracts and blood is forced into theblood vessels.

● Diastolic (lower) blood pressure:This is present when the heart muscle ex-pands and fills with blood again.

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

systolic diastolic

High blood pressure (hypertension) over 140 mmHg over 90 mmHg

Borderline normal blood pressure 130 to 139 mmHg 85 to 89 mmHg

Normal blood pressure 120 to 129 mmHg 80 to 84 mmHg

Optimum blood pressure up to 119 mmHg up to 79 mmHg

The World Health Organization (WHO) has defined the following cut-off values for assessing blood pressure:

41

�

Blood pressure values

Whether medical treatment is necessarydepends not only on the blood pressure,but also on the patient’s risk profile.Please contact your GP if one of the val-ues (systole, diastole) consistently exceedsthe cut-off point for high blood pressure.

Self-measurement of blood pressure oftenproduces somewhat lower values at home

than at the doctor’s. The GermanHypertension League has therefore defi-ned lower cut-off values for home measu-rements:

Home measurement: 135/85 mmHgMeasurement in the doctor’s surgery: 140/90 mmHg

Starting up

➡ Use only high quality leak-proof batter-ies of the correct specifications (see“Technical data” P. 59).

� Never mix old and new batteries ordifferent makes.

� If the batteries are not inserted cor-rectly, the monitor will not work and thismay cause the batteries to heat up andleak, damaging the monitor.

➡ Inserting the batteries

The battery compartment is located onthe underside of the monitor. Insert bat-teries in the battery compartment asshown in illustration 1.

➡ Remove the batteries if the monitor isnot to be used for any length of time.

+ ++ +

Illustration 1

The device must be installed and put intooperation in accordance with the instruc-tions in this manual.

43

�

Starting up

The monitor has a battery status display(see P. 35)

Flashing! No further measurements possible.Replace battery.

� Care for the environment

Do not dispose of used batteries andcharger units in domestic waste.You can take these to collection sites forused batteries or special waste.Contact your local authority for informa-tion.

General instructions for self-measurement

1. Fluctuations in blood pressure are quitenormal. Even when measurements arerepeated, there can be marked differ-ences. Single or irregular measure-ments do not provide reliable informa-tion about the actual blood pressure. Areliable evaluation is only possible if reg-ular measurements are taken undercomparable conditions and the measure-ment values entered in the blood pres-sure record card.

2. � Self-testing does not mean self-treatment. Do not on any accountchange the dose of medicine prescribedby your doctor of your own accord.

3. Irregular heartbeats can affect the accu-racy of the monitor or result in incorrectmeasurements.

4. Incorrect measurements can also occurin patients with a weak pulse (possiblyin patients wearing a pacemaker, for ex-ample). The blood pressure monitor it-self has no effect on the pacemaker.

5. If you are pregnant, consult your doctorbefore using the monitor.

6. Always take the measurement in a calmand relaxed state.You are recommended to check yourblood pressure twice a day – in the morn-ing on getting up and in the eveningonce you have relaxed after work.

7. Always measure your blood pressurefrom the arm with the higher bloodpressure values (where not required otherwise (see page 49)).

45

�

General instructions for self-measurement

To do this, measure the blood pressurefirst in both arms and thereafter alwaysfrom the arm with the higher bloodpressure.

46

�

Note on cuff sizes:

� The monitor may only be used withthe following cuff types. These should bechosen according to the upper arm cir-cumference printed on them.

* Cuff supplied as standard.

Type Arm Order numbercircumference

CA01 22 – 32 cm 143-4-760*

CA02 32 – 48 cm 143-4-757

Preparing to measure your blood pressure

Attach the cuff to the monitor by pressingthe plug (click) into the socket on the leftside of the unit. (See illustration 2).

Illustration 2

47

�

Preparing to measure your blood pressure

➡ Set the pressure selector switch‘DRUCKVORWAHL’ to the desired cuffpressure which should be at least 30 to40 mmHg higher than the systolic(upper) blood pressure reading. If youare not sure of this value, set the selec-tor switch to 150 mmHg for the firstmeasurement.

If this pressure is insufficient, the unitwill switch over to the next higher pres-sure setting automatically. Illustration 3

48

�

Preparing to measure your blood pressure

Observe the following instructionswhen measuring your blood pressure:

Avoid smoking or drinking coffeefor one hour before measuringyour blood pressure.

Sit comfortably for the blood pres-sure measurement. Support yourback and arms. Do not cross yourlegs. Place your feet flat on thefloor.Relax for 5 minutes before takinga measurement.Do not move during the measure-ment.

Attaching the cuff

The measurement should be taken fromthe bare upper arm.

� In the case of tightly fitting outer clothing, ensure that the blood supply tothe arm is not cut off when the sleeve isrolled up (if necessary remove the article ofclothing before taking the measurement).

➡ Open out the cuff into the shape of aring and slide it over the upper armuntil the bottom edge of the cuff isabout 2-3 cm above the elbow. Thecuff must be positioned so that themarking is over the artery (see illustra-tion 3).

49

�

Preparing to measure your blood pressure

� Do not attach the cuff over wounds asthis can cause further injuries.

� Ensure that the cuff is not attached toan arm where arteries or veins are under-going or have undergone medical treat-ment (e.g. shunt).

� For women who have had a breastamputated, do not attach the cuff to thearm on the amputated side of the body.

� During the measurement, medical ap-paratus that are being used on the samearm at the same time, may malfunction.

� The cuff must not be too tight. Thereshould be enough space to fit roughly twofingers between arm and cuff.

� The metal ring should never lie overthe artery (see illustration 4) as this mayproduce a false reading.

➡ Grasp the end of the cuff that feedsthough the metal ring and wrap itaround the outside of your arm. Attachthe Velcro fastener by applying gentlepressure.

� Check that the air tube is not kinkedduring the measurement. This could causecongestion of the blood flow and sub-sequent injury.

� The blood pressure measurementshould not prevent the flow of blood for anunnecessary length of time (> 2 minutes).If the monitor fails to function correctly, re-move the cuff from the arm.

� Excessive frequent measurements cancause injury by restricting blood flow.
