Semi-Automatic Blood Pressure Monitor

Introduction

Features of the device

The blood pressure monitor is digital blood pressure measuring device for use on the upper arm. It enables fast and reliable measurement of the systolic and diastolic blood pressure , as well as the pulse rate, by way of the oscillometric method. The de vice has been clinically verified to provide very accurate measurements and have been designed to be user friendly.

Operational status and cuff pressure are visible for the entire duration of the measurement on the large LCD display.

Before using the device, read through this instruction manual carefully, then keep it in a safe place. For further information on the subject of blood pressure and its measurement, contact your doctor.

Attention!

Important information about self-measurement

• Do not forget that self-measurement means «control», not

diagnosis or treatment. Unusual values must always be

discussed with your doctor. Under no circumstances should

you alter the dosages of any drugs prescribed by your doctor.

• The pulse display is not suitable for checking the pulse rate

of heart pacemakers.

2 Semi-Automatic Blood Pressure Monitor Welch Allyn

• In cases of cardiac irregularity (arrhythmia), measurements

made with this instrument should be evaluated only after

consultation with the doctor.

Electromagnetic interference:

The device contains sensitive electronic components (a microcomputer). Theref ore, avoid strong electrical or electromagnetic fields in the direct vicinity of the device (e.g., mobile telephones, microwave ovens). These can temporarily impair the measuring accuracy.

Important information on the subject of blood pressure and its measurement

How does high/low blood pressure arise?

The level of blood pressure is determined in a part of the brain, the «circulatory center», and adapted to the respective situation by way of feedback via the nervous system. Blood pressure changes when the strength and pulse rate of the heart and the width of circulatory blood vessels are altered. Blood vesse l width is affected by the fine muscles in the blood vessel walls.

The level of arterial blood pressure changes periodically with heart activity. During the blood ejection (systole), the value is maximal (systolic blood pressure value); at the end of the heart's rest period (diastole), it is minimal (diastolic blood pressure value). The blood pressu re values must lie within certain normal ranges to prevent particular diseases.

Which values are normal?

While there is no «normal» blood pressure or one combination of systolic or diastolic pressures which is right for everyone, it is generally accepted by physicians that 120/80 is a healthy blood

Directions For Use 3

pressure. During the day, the blood pressure fluctuates due to changes in activity and stress levels. These fluctuations are normal.

Blood pressure is too high if, at rest, the diastolic pressure is higher than 90 mmHg and/or the systolic blood p ressure is higher than 140 mmHg. Blood pressure is too lo w if , at rest, the diastolic pressure is lower than 60 mmHg and/or the systolic blood pressure is lower than 105 mmHg. Long-term values at these levels may endanger your health because of the continuing damage to the blood vessels in your body. However, only a doctor can correctly interpret your blood pressure.

Even with normal blood pressure v alues, a regular self-c hec k wit h your blood pressure monitor is recommended. By doing this you can detect possible ch anges in your values early and react appropriately.

If you are undergoing medical treatment to control your blood pressure, keep a record of the level of your blood pressure by carrying out regular self-measurements at specific times of the day. Show these values to your doctor.

Never use the re sults of your measur ements to alt er the dr ug doses yourself that were prescribed by your doctor.

Further information

• If your values are mostly standard under resting conditions

but exceptionally high under conditions of physical or

psyc hological stress, it is possible that y ou are suffering from

«Iabile hypertension». Consult your doctor if you suspect this

might be the case.

What can be done if regular high/low values are obtained?

1. Consult your doctor.

Hypertension is one of the major modifiable risk factors for

stroke, coronary heart disease, congestiv e heart failure , renal

failure, and peripheral vascular disease.

million people have a blood pressure level consistently at or

above 140/90 mm Hg, and therefore, are at increased risk for

developing complications.

The risk from hypertension is present whether only systolic pressure, only diastolic pressure, or both are elevated.

An estimated 50

There are many different causes of high blood pressure. Consult your doctor fo r information about th e possible origins of your own increased blood pressure values.

2. You can take measures to prevent medically established high blood pressure as well as to reduce it. These measures are part of your general way of life.

Operating the blood pressure monitor

Inserting the batteries

After you unpack your monitor, insert the batteries. The battery compartment is located on the back of the monitor (see illustration).

1. Open cover as illustrated.

2. Insert the batteries (4 AA, 1.5V), observing the correct polarity.

Attention!

• If the battery warning symbol appears (as shown in the diagram ), the monitor is unusable until the batteries have been replaced.

• Use AA long-life or alkaline

1.5V batteries. The use of rechargeable batteries is not recomme nded.

• If the blood pressure monitor is left unused for long periods, remove the batteries from the device.

Functional check: Hold down the Start/ Stop button to test all the displa y elements. When functioning correctly, all segments will appear .

Tube connection

Insert the cuff tube into the opening provided on the left side of the monitor, as shown in the diagram.

Carrying out a measurement

Before the measurement:

• Avoid eating, smoking, and all forms of exertion directly before performing the measurement. All these factors influence the measurement results.

• Relax by sitting in an armchair in a quiet atmosphere for about 10 minutes before the measurement.

• Remove any garment that fits closely to your upper arm.

• Always measure on the same arm (preferably left).

• Attempt to carry out the measurements regularly at th e same time of day, since blood pressure changes during the course of the day.

Directions For Use 9

Common sources of error

Note:

Comparable blood pre ssure measurements always require the same conditions. These should be quiet conditions.

• All efforts by the patient to support the arm can in crease the blood pressure. Make sure you are in a comfortable, relaxed position and do not activate any of the muscles in the arm being measured during the procedure. Use a cushion for support if necessary.

• If the arm artery lies considerably lower or higher than the heart, an erroneous blood pressure will be measured. (Each 15 cm difference in height results in a measurement error of 10 mmHg.)

• Cuffs that are too narrow or too short result in false measurement values. Selecting the correct cuff is very important. The cuff size is dependent upon the circumference of the arm (measured midway between the armpit and elbow). The permissible range is printed on the cuff. If this is not suitable for your use, contact your dealer.

Note: Only use clinically approved original cuffs.

• A loose cuff or a sideways protruding air pocket causes false measurement values.

• With repeated measurements, blood accumulates in the tested arm, which can lead to false results. Correctly executed bloo d pressure measurements, therefor e, should be repeated at least 30 seconds after pr evious attempts.

10 Semi-Automatic Blood Pressure Monitor Welch Allyn

Fitting the cuff

1. Pass the end of the cuff (with sewn-in rubber stopper) through the metal stirrup so a loop is formed. The Velcro closure must be facing outward. (Ignore th is step if the cuff has already been prepared.)

2. Push the cuff over the left upper arm so the tube points in the direction of the lower arm.

3. Lay the cuff on the arm as illustrated. It is important that the tube coming out of the cuff l ies over the brachial artery, located just to the inside of the bicep. Make certain that the lower edge of the cuff lies approximately 2 to 3 cm above the elbow and that the rubber tube leaves the cuff on the inne r side of the arm.Tighten the free end of the cuff and close the cuff with the Velcro closure.

4. There must be no free space between the arm and the cuff. Clothing must not restrict the arm. Any piece of clothing that does must be taken off.

Directions For Use 11

5. Secure the cuff with the Velcro closure in such a way that it lies comfortably and is not too tight. Lay the arm on the table (palm upward) so the cuff is at the same height as the heart. Make sure the tube is not kinked.

6. Remain seated quietly for two minutes before you begin the measurement.

Note: If it is not possible to fit the cuff to the left arm, it can be placed on the right one. However, all measurements should be made using the same arm.

Measuring procedure

After the cuff has been positioned appropriately, the measurement can begin.

1. Press the Start/Stop button. The tube should not yet be attached to the instrument. The following appears in the display for 2 seconds: (Diag.). A short tone follows to indicate that the instrument has equalized wit h the pressure of the surroundings and the measurement can therefore begin. A «O» is shown in the display.

2. Plug the T-connecting piece or the free end of the tube into the left side of the instrument.

3. Grasp the bulb with your free h and and inflate the cuf f to a press ure at least 20 to 30 mmHg higher than the expected systolic pressu re. If you do not know the value of this pressure, inflate to a value of approximately 160 to 180 mmHg. The cuff pressure is shown continuously on the LCD.

4. After the inflation process, lay down the bulb and remain in a quiet and relaxed sitting position. The measurement now proceeds on its own. If no measurement takes place and all that appears in the display is a flashing, upward pointing arrow, see below under «Inflating further». When the instrument detects a pulse, a heart symbol in the displa y s tarts to flash and a beep occurs for every heart beat.

5. When the measurement has been concluded, a long tone will sound. The measured systolic and diastolic blood pressure values, as well as the pulse rate, will be displayed. The cuff pressure can then be released quickly by pressing the release valve at the bulb.

Directions For Use 13

Inflating further

If the cuff is not inflated sufficiently, the measurement is broken off after a few seconds and a flashing arrow pointing upward appears in the display. It is then necessary to inflate further to at least 20 mmHg higher than the previous value. The instruction to inflate further will appear every time the pressure is not sufficient.

Attention! If the cuff is inflated too far (higher than 300 mmHg) «HI» appears in the display and a warning signal sounds. The cuff pressure must then be released immediately using the quick-release valve at the bulb.

Discontinuing a measurement

If it is necessary to interrupt a blood pressure measurement for any reason (e.g., the patient feels ill), press the quic k-release valve at the bulb. The device immediately lowers the cuff pressure.

Memory - displaying the last measurement

The blood pressure monitor automatically stores the last measurement value. Press the Start/Stop button for at least three seconds, the last measurement will be displayed

Further information

Measurements should not occur soon after each other, otherwise the results will be false. Therefore, wait at least 30 seconds in a relaxed position, sit t ing or lying, before yo u repeat a measurement.

3 sec.

Error messages/malfunctions

If an error occurs during a measurement, the measurement will be discontinued and a corresponding error code will be displayed.

Directions For Use 15

Error No. Possible cause(s)

ER 1 The systolic pressure was determined, but afterwards the cuff pressure

fell below 20 mmHg. This situation can occur, for example, if the tube becomes unplugged after the systolic blood pressure has been measured. Further possible cause: No pulse could be detected.

ER 2 The pressure dropped below 20 mmHg without a measurement taking

place. This situation can occur if the release valve was pressed during the measurement.

Other possible malfunctions and their remedies

If problems occur when using the device, the following points should be checked and if necessary, the corresponding measures are to be taken:

Malfunction Remedy

The display remains blank when the instrument is switched on, although the batteries are in place.

The pressure does not rise although the bulb is being squeezed.

The device frequently fails to measure the blood pressure values, or the values measured are too low or too high.

Every measurement results in different values, although the device functions normally and normal values are displayed.

1.Check whether the batteries are installed with the correct polarity, then correct if necessary.

2. If the display remains blank, remove the batteries, then replace them, or exchange them for new ones.

Check the connection of the cuff tube and connect it properly if necessary.

1. Fit the cuff correctly on the arm.

2. Before starting the measurement, make sure the cuff is not fitted too tightly and that there is no rolled-up sleeve exerting pressure on the arm above the measuring position. Take off articles of clothing if necessary.

3. Measure the blood pressure again in complete silence.

Read the following information and the points listed under «Common sources of error». Repeat the measurement.

Malfunction Remedy

The blood pressure values measured differ from those measured by the doctor.

Further information

The level of blood pressure is subject to fluctuations, even with healthy people. It is impor tant to understand that compar able measurements always require the same conditions. If, in spite of observing all thes e factors, the fluctuations are larger than 15 mmHg and/or you hear irregular pulse tones on several occasions, consult your doctor.

Einführung

Besonderheiten des Gerätes:

Das Blutdruckmessgerät ist ein halbautomatisches, digitales Blutdruckmessgerät zur Verwendung am Oberarm, welches eine sehr rasche und zuverlässige Messung des systolischen und diastolischen Blutdruckes sowie der Pulsfre quenz mittels oszillometrischem Messverfahren ermöglicht. Das Gerät bietet eine klinisch erprobte sehr hohe Messgenauigkeit und wurde für ein Maximum an Bedienerfreundlichkeit ausgelegt.

Dank der grossen LCD-Anzeige sind Betriebszustand und Manschettendruck während der gesamten Messdauer gut ablesbar.

Bitte lesen Sie diese Anleitung vor dem Gebrauch sorgfältig durch und bewahren Sie diese anschliessend gut auf. Für weitere Fragen zum Thema Blutdruck und dessen Messung sprechen Sie bitte mit Ihrem Arzt.

Sicherheitshinweise!

Wichtige Hinweise für die Selbstmessung

• Denken Sie daran: Selbstmessung bedeutet Kontrolle, keine Diagnosenstellung oder Behandlung. Auffällige Werte müssen immer mit Ihrem Arzt besprochen werden. Verändern Sie auf keinen Fall von sich aus die von Ihrem Arzt verschriebene Dosierung von Arzneimitteln.

• Die Pulsanzeige ist nicht g eeignet zur Kontrolle der F requenz v on Herzschrittmachern!

• Bei Herzrhythmusstörungen (Arrhythmien) sollte n Messungen mit diesem Gerät erst nach Rücksprache mit dem Arzt bewertet werden.

Elektromagnetische Störungen:

Das Gerät enthält empfindliche elektronische Bauelemente (Mikrocomputer). Vermeiden Sie daher starke elektrische oder elektromagnetisc he Felder in direkter Umgebung des Gerätes (z. B. Mobiltelefone, Mikrowellenherd). Diese kö nnen zu einer vorübergehenden Beeinträchtigung der Messgenauigkeit führen.

Wichtige Informationen zum Thema Blutdruck und dessen Messung

Wie entsteht hoher/niedriger Blutdruck?

Die Höhe des Blutdrucks wird in einem Teil des Gehirns, dem sog. Kreislaufzentrum bestimmt und dur ch Rückmeldungen über Nervenbahnen der jeweiligen Situation angepasst. Zur Einstellung des Blutdruckes wird die Schlagkraft und Frequenz des Herzens (Puls), sowie die Gefässweite des Kreislaufs verändert. L etzteres er folgt durch feine Muskeln in d en Blutgefässwänden. Die Höhe des arteriellen Blutdruckes verändert sich periodisch innerhalb der Herztätigkeit: Während des «Blutauswurfes» (Systole) ist der Wert maximal (systolischer Blutdruckwert), am Ende der «Herzruhepause» (Diastole) minimal (diastalischer Blutdruckwert). Die Blutdruckwerte müssen zur Vermeidung bestimmter Krankheiten in bestimmten Normalbereichen liegen.

Welche Werte sind normal?

Zu hohe Blutdruc kw erte liegen v or, wenn in Ruhe der diastolisc he Druck über 90 mmHg liegt und/oder der systolische Blutdruck über 160 mmHg liegt. In diesem Fall wenden Sie sich bitte unverzüglich an Ihren Arzt. Langfristige Werte in dieser Höhe gefährden Ihre Gesundheit aufgrund einer damit verbundenen fortschreitenden Schädigung der Blutgefässe Ihres Körpers.
