■ Ensure that you have all the following components.

• Blood pressure monitor unit • Instruction Manual

• 4 AA-size batteries (for monitor)

• Cuff (model: SCN-008) for CHU304

• Wide Range Cuff (model: SCW-009) for CHU305

GENERAL REMARKS

General remarks on blood pressure and blood pressure measurement

1. To deflate the cuff quickly, press the “START/STOP” switch.

2. Before applying your blood pressure cuff, be sure you have selected the appropriate size cuff:

Cuff (model: SCN-008) fits arm circumference: 22 cm – 30 cm.

Wide Range Cuff (model: SCW-009) fits arm circumference: 22 cm – 42 cm.

3. When attaching the cuff, adjust the position of the cuff so that the air hose is located in the center of your arm and the hem of the cuff is 1 cm – 2

Űcm above your elbow.

4. Self measurement is not therapy! In no event should you change the dosage of your medication prescribed by your physician.

5. As preparation for measuring your blood pressure, you should urinate and then remain relatively still for 10 to 15 minutes prior to measurement.

6. DO NOT place too much emphasis on the results of one measurement. Keep a continuing record of your blood pressure variations. A complete picture can only be obtained from a large number of readings.

To obtain correct blood pressure measurements

1. Take five or six deep breaths and then relax before measuring your blood pressure.

If you are tense when taking the measurement, you will not get a valid reading.

2. Your blood pressure will be elevated if you are anxious or irritated, suffering from lack of sleep or constipation, or have just taken some exercise or eaten a meal.

- Eng 1 -

00_CHU304_All.indb Eng-1 2015/06/02 11:00:47

3. Wrap the cuff around your arm and tighten it so that one finger can be inserted between the cuff and arm. ( See page 9, 10)

4. DO NOT measure your blood pressure after bathing or drinking.

5. Measure your blood pressure where the room temperature is around 20°C.

DO NOT measure your blood pressure when it is too cold (below 10°C) or too hot (above 40°C) in the room.

6. DO NOT try to measure your blood pressure immediately after drinking coffee or tea or after smoking.

7. Measure your blood pressure when you are relaxed and still. Keep the center of the cuff at the level of your heart and DO NOT move your arm or talk.

8. DO NOT measure blood pressure when the cuff has been on your arm for a few minutes or more. During this time, your arm will have built up a higher blood pressure and you will not get valid reading.

9. If the Irregular Heartbeat (IHB) Indicator is displayed, relax and measure your blood pressure again. If the Irregular Heartbeat (IHB) Indicator appears frequently, you are advised to consult a doctor about your health condition.

( See page 11)

10. The figure below shows the blood pressure classifications under the WHO standards.

Remarks:

The graph is not exact, but may be used as a guide in understanding non-invasive blood pressure measurements.

The device is only intended for use by adults.

Definitions and Classifications of Blood Pressure Levels

* This unit is equipped an indicator which visually indicates the blood pressure classification (Optimal/Normal/High-Normal/Grade 1 Hypertension/Grade 2

Hypertension/Grade 3 Hypertension) of the result after each measurement.

11. Intended Use

• This device is noninvasive blood pressure monitor by oscillometric method.

This device can measure the systolic blood pressure (SYS), the diastolic blood pressure (DIA) and the pulse rate automatically.

• This device is intended to be used for checking personal health condition at home under the direction of a physician and is not intended to be a diagnostic device.

• This device is not intended for use with neonates or infant, and not intended for automatic cycling measurement.

Measure your blood pressure at the same time each day.

* Your blood pressure changes all the time. This means that data gathered over a long period has far more significance than data from just one measurement.

For this reason, you must measure your blood pressure on a daily basis. Ideally, you should measure your blood pressure at the same time each day, wherever possible.

PRECAUTIONS FOR USE AND MAINTENANCE

Precautions for use

1. If you suffer from heart disease, high blood pressure or other circulatory disease, consult your physician before using the monitor.

2. Inflating to a higher pressure may result in bruising where the cuff is applied.

If the cuff pressure feels abnormal or you experience any other irregularity while using the cuff, reduce the pressure immediately by pressing the “START/STOP” switch, detach the cuff or unplug the air hose connector from the monitor and then consult the sales outlet where you purchased the monitor.

3. If you think the measurement is abnormal or if measurement makes you feel unwell, discontinue use and consult your physician.

4. Blood pressure measurement may not be possible for anyone with a weak pulse or arrhythmia.

5. Repeated blood pressure measurement and prolonged overinflation may cause problems such as congestion or swelling in some people.

6. Frequently repeated blood pressure measurements will not give accurate results. Allow an interval of about 1 minute between measurements.

7. If you suffer from a severe problem with blood circulation in your arms, consult your physician before using the monitor. Failure to do so could be hazardous to your health.

8. Measurement may not be possible for anyone with insufficient blood flow to the area where measurements will be taken or who suffers from a frequent irregular heartbeat. Consult your physician for advice on whether to use the monitor.

9. DO NOT wrap the cuff around an injured arm.

10. DO NOT wrap the cuff around an arm in which a drip (intravenous infusion) is inserted or which is being used for blood transfusion as part of medical treatment. Doing so could result in an injury or a serious accident.

11. Do not share the cuff with other infective person to avoid cross-infection.

12. If you have any doubt about the application of the cuff on the arm on the side of a mastectomy, consult your physician.

13. DO NOT use the monitor in the vicinity of flammable gases such as those used for anaesthesia. Doing so could ignite the gases and cause an explosion.

14. DO NOT use the monitor in enriched oxygen environments such as a hospital’s hyperbaric chamber or oxygen tent. Doing so could ignite the oxygen and cause a fire.

15. DO NOT use mobile phones near the monitor as this could result in a malfunction.

16. If you use a cardiac pacemaker, consult your physician before using the monitor.

Technical Alarm Description

The monitor will show ‘HI’ or ‘Lo’ as technical alarm on LCD with no delay if the determined blood pressure (systolic or diastolic) is outside the rated range specified in part SPECIFICACIONS. In this case, you should consult a physician or check if your operation violated the instructions.

The technical alarm condition (outside the rated range) is preset in the factory and cannot be adjusted or inactivated. This alarm condition is assigned as low priority according to IEC 60601-1-8. The technical alarm is non-latching and need no reset.

The signal displayed on LCD will disappear automatically after about 8 seconds.

TIPS FOR OBTAINING ACCURATE MEASUREMENTS

Your blood pressure varies according to your posture, the time of day and a range of other factors. Ideally, you should measure your blood pressure in the same posture at the same time every day.

■ Taking measurements while sitting

* Be seated comfortably with your feet flat on the floor, and don't cross your legs.

1 Place your arm on a table or similar surface with your forearm extended.

2 It is important to have the cuff level with your heart.

3 Open your hand slightly on the table so that your palm is facing up and your fingers are relaxed.

4 Do not move your body or talk while taking the measurement.

■ Measurement in a reclining posture

* Relax yourself to avoid placing pressure on the cuff.

■ You may use your right arm to measure your blood pressure.

Blood pressure value is likely to differ by as much as 10 mmHg when measured on the right arm instead of the left (or vice-versa). Measure your blood pressure on the same arm each day.

CALLING UP THE DATA STORED IN MEMORY

99 measurement results can be stored in

Memory.

ABOUT “BLOOD PRESSURE”

What is blood pressure?

The heart is a pump that circulates blood throughout your body. Blood is pumped from the heart at a constant pressure into arteries. This pressure is called the arterial blood pressure and represents, in general terms, your blood pressure. Blood pressure

(Systolic)

Left atrium

Left ventricle

Artery

The artery wall expands.

Contraction

(Diastolic)

Left atrium

Left ventricle

Artery

Normal state is restored to the artery wall.

Dilation is indicated by several kinds of pressures, including the systolic pressure that occurs when the heart pumps blood, and the diastolic pressure that occurs when blood returns to the heart.

Your blood pressure changes all the time.

Your blood pressure differs according to your age, gender and a range of other factors. It is likely to be affected by your biorhythm during the day and by your posture, physical activities, mental activities, level of stress and even by the air temperature. The blood pressure of a healthy person generally varies within a day.

BLOOD PRESSURE Q&A

Q

Why is the blood pressure measured at home different from that measured by the physician or at a hospital?

A

Your blood pressure may vary due to exercise, the ambient temperature or your mental state. When you have a physician or nurse measure your blood pressure, the pressure value is likely to be 10 to 20 mmHg higher than usual due to anxiety and/or stress.

Knowing what affects your blood pressure helps you to better monitor your health.

Q

Why does the blood pressure obtained vary with measurement?

A

Our blood pressure is adjusted by automatic nerve function. Blood pressure differs with every heart beat. We are likely to think that our blood pressure is constant, but it varies if you take measurements in repetition. Blood pressure is susceptible to the time of day, such as morning and afternoon, season and atmospheric temperature.

In addition, blood pressure is easily affected by mental stress or emotional ups and downs. It tends to increase when you feel tension or decrease when you are relaxed.

Q

What is the benefit of measuring my blood pressure at home?

A

Blood pressure measurements taken at home give reliable data as they can be taken when you are in a stable and relaxed condition. Physicians place considerable importance on blood pressure measurements taken at home. You should measure your blood pressure at the same time each day and record the variations in your blood pressure.

Always consult your physician for an interpretation of your blood pressure readings and to determine the proper treatment.

Field strengths from Þ xed RF transmitters, as determined by an electromagnetic site survey, a)

should be less than the compliance level in each frequency range.

b)

Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reß ection from structures, objects and people.

a). Field strengths from Þ xed transmitters, such as base stations for radio (cellular/ cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to Þ xed RF transmitters, an electromagnetic site survey should be considered. If the measured

Þ eld strength in the location in which the [CHU304/CH305] is used exceeds the applicable RF compliance level above, the [CHU304/CH305] should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the [CHU304/CH305].

b). Over the frequency range 150 kHz to 80 MHz, Þ eld strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the [CHU304/CH305]

The [CHU304/CH305] is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the [CHU304/CH305] can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the deivce as recommended below, according to the maximum output power of the communications equipment.
