Wrist Watch Blood

Pressure Monitor

1. Introduction

1.1. Features of the device

The blood-pressure monitor is a fully automatic, digital blood-

pressure measuring device for use on the wrist, which enables

very fast and reliable measurement of the systolic and diastolic

blood-pressure as well as the pulse frequency by way of the

oscillometric method of measuring.

The device offers a very high and clinically tested measurement

accuracy and has been designed to provide a maximum of user-

friendliness.

Before using, please read through this instruction manual

carefully and then keep it in a safe place. For further questions on

the subject of blood-pressure and its measurement, please

contact your doctor.

Attention!

1.2. Important information about self-measurement

• Do not forget: 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 frequency

of heart pacemakers!

2 Wrist Watch Blood Pressure Monitor Welch Allyn

• In cases of cardiac irregularity (Arrhythmia), measurements

made with this instrument should only be evaluated after

consultation with the doctor.

Electromagnetic interference

The device contains sensitive electronic components

(Microcomputer). Therefore, avoid strong electrical or

electromagnetic fields in the direct vicinity of the device (e.g.

mobile telephones, microwave cookers). These can lead to

temporary impairment of the measuring accuracy.

2. Important information on the subject

of blood-pressure and its measurement

2.1 How does high/low blood-pressure arise?

The level of blood-pressure is determined in a part of the brain,

the circulatory centre, and adapted to the respective situation by

way of feedback via the nervous system.

To adjust the blood-pressure, the strength and frequency of the

heart (Pulse), as well as the width of circulatory blood vessels is

altered. The latter is effected by way of fine muscles in the blood

vessel walls.

The level of arterial blood-pressure changes periodically during

the 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-pressure values must lie within certain normal ranges

in order to prevent particular diseases.

2.2 Which values are normal?

Blood pressure is too high if at rest, the diastolic pressure is

above 90 mmHg and/or the systolic blood-pressure is over 160

mmHg. In this case, please consult your doctor immediately.

Directions For Use 3

Long-term values at this level endanger your health due to the

associated advancing damage to the blood vessels in your body.

Should the systolic blood-pressure values lie between 140

mmHg and 160 mmHg and/or the diastolic blood-pressure values

lie between 90 mmHg and 95 mmHg, please consult your doctor.

Furthermore, regular self-checks will be necessary.

With blood-pressure values that are too low, i.e. systolic values

under 105 mmHg and/or diastolic values under 60 mmHg, please

consult your doctor.

Even with normal blood-pressure values, a regular self-check with

your blood-pressure monitor is recommended. In this way you

can detect possible changes in your values early and react

appropriately.

If you are undergoing medical treatment to control your blood

pressure, please 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

results of your measurements to alter independently the

drug doses prescribed by your doctor.

Further information

• If your values are mostly standard under resting conditions

but exceptionally high under conditions of physical or

psychological stress, it is possible that you are suffering from

«labile hypertension». Please consult your doctor if you

suspect that this might be the case.

• Correctly measured diastolic blood-pressure values above

120 mmHg require immediate medical treatment.

2.3. What can be done if regular increased/low

values are obtained?

1. Please consult your doctor.

2. Increased blood-pressure values (various forms of

hypertension) are associated long- and medium term with

considerable risks to health. This concerns the arterial blood

vessels of your body, which are endangered due to

constriction caused by deposits in the vessel walls

(Arteriosclerosis). A deficient supply of blood to important

organs (heart, brain, muscles) can be the result. Furthermore,

with long-term continuously increased blood-pressure

values, the heart will become structurally damaged.

3. There are many different causes of the appearance of high

blood pressure. We differentiate between the common

primary (essential) hypertension, and secondary

hypertension. The latter group can be ascribed to specific

organic malfunctions. Please consult your doctor for

information about the possible origins of your own increased

blood pressure values.

4. There are measures which you can take, not only for

reducing a medically established high blood pressure, but

also for prevention. These measures are part of your general

way of life:

Directions For Use 5

Eating habits

• Strive for a normal weight corresponding to your age. Reduce

overweight!

• Avoid excessive consumption of common salt.

• Avoid fatty foods.

Previous illnesses

• Follow consistently any medical instructions for treating

previous illness such as:

• Diabetes (Diabetes Miletus)

• Fat metabolism disorder

• Gout

Habits

• Give up smoking completely

• Drink only moderate amounts of alcohol

• Restrict your caffeine consumption (Coffee)

Physical constitution:

• After a preliminary medical examination, do regular sport.

• Choose sports which require stamina and avoid those which

require strength.

• Avoid reaching the limit of your performance.

• With previous illnesses and/or an age of over 40 years,

please consult your doctor before beginning your sporting

activities. He will advise you regarding the type and extent of

types of sport that are possible for you.

3. The various components of the blood-

pressure monitor

The illustration shows the blood-pressure monitor, consisting of:

6 Wrist Watch Blood Pressure Monitor Welch Allyn

Wrist cuff Type WC1 13.5--19.5 cm, for wrist circumference of

13.5 to 19.5 cm

4. Putting the blood-pressure monitor

into operation

4.1. Inserting the batteries

After you have unpacked your device, first insert the batteries.

The battery compartment is located on the left lateral side of the

device (see illustration).

1. Remove cover as illustrated.

2. Insert the batteries (2 x size AAA 1.5V), observing the

indicated polarity.

3. If the battery warning appears in the display, the batteries are

empty and must be replaced by new ones.

Directions For Use 7

Attention!

• After the battery warning appears, the device is blocked until

the batteries have been replaced.

• Please use «AAA» Long-Life or Alkaline 1.5V Batteries. The

use of 1.2V Accumulators is not recommended.

• If the blood-pressure monitor is left unused for long periods,

please remove the batteries from the device.

Functional check: Press and hold the O/I button to test all the

display elements. When functioning correctly all segments

appear for about 2 seconds (If the 0/l button is pressed and held

for up to 3 seconds, the last measured value will be displayed).

5. Carrying out a measurement

5.1. Before the measurement:

• Avoid eating, smoking, as well as all forms of exertion

directly before the measurement. All these factors influence

the measurement result. Try and find time to relax by sitting

in an armchair in a quiet atmosphere for about ten minutes

before the measurement.

• Always measure on the same wrist (normally left).

• Attempt to carry out the measurements regularly at the

same time of day, since the blood-pressure changes during

the course of the day.

5.2. Common sources of error.

Note:

Comparable blood-pressure measurements always require the

same conditions! These are always quiet conditions.

• All efforts by the patient to support the arm can increase the

blood-pressure. Make sure you are in a comfortable, relaxed

position and do not activate any of the muscles in the

8 Wrist Watch Blood Pressure Monitor Welch Allyn

measurement arm during the measurement. Use a cushion

for support if necessary.

• If the wrist artery lies considerably lower (higher) than the

heart, an erroneously higher (lower) blood-pressure will be

measured! (Each 15 cm difference in height results in a

measurement error of 10 mmHg!)

• A loose cuff causes false measurement values.

• With repeated measurements, blood accumulates in the

respective arm, which can lead to false results. Correctly

executed blood-pressure measurements should therefore

first be repeated after a 5 minute pause or after the arm has

been held up in order to allow the accumulated blood to flow

away (after at least 3 minutes).

5.3. Fitting the cuff

1. Remove all objects and

jewellery (e.g. wristwatch)

from the wrist in question.

2. Draw the cuff over the wrist.

3. The distance between the

cuff and the hand should be

approximately 10 mm.

4. Secure the cuff with the

Velcro fastener, so that it lies

comfortably and not too tight

whereby no space should remain between the cuff and the

wrist.

5. Lay the arm on a table, with the palm upwards. Support the

arm with a rest (cushion), so that the cuff rests at about the

same height as the heart. Take care, that the cuff lies free.

Remain so for 2 minutes sitting quietly, before beginning

with the measurement.

5.4. Measuring procedure

After the cuff has been appropriately positioned, the

measurement can begin:

1. Press the O/l-button, the pump

begins to inflate the cuff. In the

display, the increasing cuff-

pressure is continually displayed.

2. After reaching the inflation

pressure, the pump stops and the pressure

slowly falls away. The cuff-pressure (large

characters) is displayed during the

measurement. When the device has detected

the pulse, the heart symbol in the display

begins to blink and a beep tone is audible for

every pulse beat.

3. When the measurement has been concluded,

a long beep tone sounds. The measured

systolic and diastolic blood-pressure values as

well as the pulse frequency are now displayed.

Example (Fig.): Systole 118, Diastole 73, Pulse 75

The measurement results are displayed, until you

switch the device off. If no button is pressed for 5 minutes, the

device switches automatically off, to save the batteries.

5.5. Discontinuing a measurement

If it is necessary to interrupt a blood pressure

measurement for any reason (e.g. the patient

feels unwell), the O/l button can be pressed at

any time. The device then immediately lowers

the cuff-pressure automatically.

5.6. Memory - storage and recall of the

measurements

The blood-pressure monitor

automatically stores the last

measurement value. By pressing the

O/l button (when the power is off) for up

to 3 seconds, the last measurement can

be displayed.

Further information

Measurements should not occur soon after each other, since the

results will be falsified. Wait for several minutes in a relaxed

position, sitting or lying, before you repeat a measurement.

6. Error messages/malfunctions

If an error occurs during a measurement, the

measurement is discontinued and a

corresponding error code is displayed (Example:

Error No. 2).

should be checked and if necessary, the corresponding measures

are to be taken:

Further Information

The level of blood-pressure is subject to fluctuations even with

healthy people. Comparable measurements always require

the same conditions (Quiet conditions)!

If, in spite of observing all these factors, the fluctuations are

larger than 15 mmHg, and/or you hear irregular pulse tones on

several occasions, please consult your doctor.

This device has been subjected to strict clinical tests. The

conformity of this product with the requirements of the CE-

Error 3 The inflation of the cuff takes too long. The cuff is not correctly seated.

Malfunction Remedy

The display remains empty when

the instrument is switched on

although the batteries are in

place.

1. Check batteries for correct polarity and , if

necessary, insert correctly.

2. If the display is unusual, re-insert batteries

or exchange them.

The device frequently fails to

measure the blood pressure

values, or the values measured

are too low (too high).

1. Check the positioning of the cuff.

2. Measure the blood-pressure again in peace

and quiet under observance of the details

made in point 5.

Every measurement results in

different values, although the

device functions normally and

normal values are displayed.

Please pay attention to the following

information as well as the points listed under

«Common Sources of Error» and repeat the

measurement.

The blood pressure values

measured differ from those

measured by the doctor.

Record the daily development of the values

and consult your doctor about them.
