Panasonic Oscillometric Diagnostec™ Automatic Wrist Blood Pressure Monitor Model EW-BW30 is a device intended to measure systolic and diastolic blood pressure and pulse rate of an adult individual by using a pressurized cuff on the wrist. The device is not intended for use on neonatal, infants and children. The device is designed for home use only, not for ambulatory measurement (measurement recorded continuously during the day).

Speciﬁcations of this device are listed in page 31.

Blood pressure measurements determined with this device are equivalent to those obtained by a trained observer using the cuff/ stethoscope auscultation method, within the limits prescribed by the American National Standard, Manual, Electronic or automated sphygmomanometers.

If you suffer from disorder of heart rhythm, known as arrhythmia only use this blood pressure monitor in consultation with your doctor. In certain cases oscillometric measurement method can produce incorrect readings.

Flashing System for hypertensive readings are based on blood pressure values classiﬁed in the paper: “JNC 7 Express; The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure; U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES; National Institute of Health; National Heart, Lung, and Blood Institute; National High Blood Pressure Education Program; NIH Publication No. 03-5233; May 2003.” The display values are generally known, but not proven, to be an indicator of your blood pressure.

The EW-BW30 is not intended to be used as a diagnostic device. Contact your physician if prehypertensive or hypertensive values are indicated.

Introduction

Thank you for purchasing the Panasonic Automatic Wrist Blood Pressure Monitor EW-BW30.

Measuring your own blood pressure is an important way of monitoring your health. High blood pressure (hypertension) is a major health problem which can be treated effectively once detected. Measuring your blood pressure between doctor visits on a regular basis in the comfort of your home, and keeping a record of the measurements, will help you monitor any signiﬁcant changes in your blood pressure. Keeping an accurate record of your blood pressure will help your doctor diagnose and possibly prevent any health problems in the future.

Basics of Blood Pressure

Your heart acts like a pump, sending blood surging through your blood vessels each time it contracts. Blood pressure is the pressure exerted by blood pumped from the heart on the walls of blood vessels. Systolic pressure is the pressure exerted when the heart contracts and pumps blood into the arteries. Diastolic pressure is the pressure exerted when the heart expands, or relaxes. When you or your doctor take your blood pressure, both your systolic and diastolic pressures are measured. If your blood pressure measurement is 120 mmHg over 80 mmHg (120/80), for example, your systolic pressure is 120 mmHg while your diastolic pressure is 80 mmHg.

English

Important Instructions Before Use

1. Do not confuse self-monitoring with self-diagnosis. Blood pressure measurements should only be interpreted by a health care professional who is familiar with your medical history.

2. If you are taking medication, consult with your physician to determine the most appropriate time to measure your blood pressure. NEVER change a prescribed medication without first consulting with your physician.

3. For persons with irregular or unstable circulation resulting from diabetes, liv there may be variations in blood pressure values measured at the wrist versus at the upper arm. Monitoring the trends in your blood pressure taken at either the arm or the wrist is nevertheless useful and important.

4. Blood pressure can vary based on many f gender, weight and physical condition. In general, a person’s blood pressure is lower during sleep and higher when he or she is active. Blood pressure can change easily in response to physiological changes. The setting in which a person’s blood pressure is measured can also affect the results. Having one’s blood pressure measured by a healthcare professional in a hospital or clinic can cause nervousness and may result in a temporarily elevated reading. Because blood pressure measurements taken in a clinical setting can vary considerably from those taken at home, a person’s blood pressure should be measured not only occasionally in the doctor’s office, but also on a regular basis at home. Also, if you find that your blood pressure is lower at home, this is not unusual. To accurately compare with your physician’s reading, take your Panasonic blood pressure monitor to your doctor’s office and compare readings in this setting.

5. People suffering from cardiac arrh disorders or diabetes, people with cardiac pacemakers or a weak pulse, and women who are pregnant should consult their physician before measuring their blood pressure themselves. Different values may be obtained due to their condition.

6. Try to take y under the same conditions every day.

The ideal time to measure your blood pressure (to obtain your so-

•

called “base blood pressure”) is in the morning just after waking up, before having breakfast and before any major activity or exercise. If

English

this is not possible, however, try to take measurements at a specified time prior to breakfast, and before you have become active. You should relax for about 5 minutes before taking the measurement. The following situations may cause substantial variations in blood pressure readings and should therefore be avoided at least 30 minutes prior to taking your blood pressure. Blood pressure will be higher than usual:

- when you are excited or tense

- when you are taking a bath

- during exercising or soon after exercising

- when it is cold

- within one hour after eating

- after drinking coffee, tea or other beverages containing caffeine

- after smoking tobacco

- when your bladder is full

- when in a moving vehicle Blood pressure will be lower than usual:

- after taking a bath

- after drinking alcohol

7. Measurements may be impaired if this unit is used near a television, microwave oven, X-ray equipment or other devices with strong electrical fields. To prevent such interference, use the unit at a sufficient distance from such devices or turn the devices off.

8. This unit is designed for use by adults.

Consult with your physician before using this unit on a child. Do not use on neonatal, infants and children.

9. This unit is not suitable for continuous monitor

ing during medical

emergencies or operations.

10. Do not use the unit for any purpose other than measur

ing blood

pressure. Do not use the unit together with other devices.

11. Improper handling of batteries may result in battery r

upture or in corrosion from battery leakage. Please observe the following to ensure proper use of batteries. a. Be sure to turn off the power after use

. b. Do not mix different types or sizes of batteries. c. Change all batteries at the same time. Do not mix old and new

English

g. Do not short-circuit batteries. h. Do not attempt to recharge the batteries included with the unit.

12. Please remove the cuff if abnormal operation, such as prolonged overinflation, is observed.

Differences in Blood Pressure Values Measured at the Wrist Versus at

the Upper Arm For persons with peripheral circulatory disorders* resulting from diabetes, liver or kidney disease, arteriosclerosis or hypertension, etc., there may be variations in blood pressure values measured at the wrist versus at the upper arm. Therefore, always consult with a health professional rather than attempting to interpret blood pressure measurements yourself. * Persons with underlying medical conditions with bad circulation in

their hands and feet.

Precautions to Ensure Safe, Reliable Operation

1. Do not drop the unit. Protect it from sudden jars or shocks.

2. Do not insert foreign objects into any openings.

3. Do not attempt to disassemble the unit.

Obtaining Accurate Measurements

Always take your blood pressure at the same time while sitting in the same position and using the same wrist.

It is recommended to check your blood pressure at least twice a day. It is best in the morning before breakfast and in the evening after work.

In the following situations, accurate measurements cannot be taken.

Within 1 hour after eating or drinking alcohol

• Immediately after drinking coffee or tea, or smoking

• In a moving vehicle

• Immediately after exercising or taking a bath

• (Wait at least 20 minutes and take a measurement while staying quiet.) In cold places

• [Take measurements at room temperatures around 68 °F (20 °C).] When you need to urinate

• (Wait several minutes after urinating before taking measurements.)

Always rest for four to ﬁve minutes before taking your blood pressure.

Taking measurements while sitting down

1. Place your elbow on the table.

2. Align the device with the level of

your heart.

3. Open and relax your hand with

the palm facing up.

Please place your arm on top of the storage case once you have attached the pressure cuff.

English

Obtaining Accurate Measurements

Do not take measurements in the positions shown below as they will be

inaccurate.

Do not bend your wrist inward. Do not clench your ﬁst.

(cont.)

If the device is placed at a height lower than the heart then the resulting readings may be higher than your actual blood pressure.

If the device is placed at a height higher than the heart then the resulting readings may be lower than your actual blood pressure.

If you lean forward while taking measurements then the resulting readings may not be accurate.

To obtain accurate readings, the following actions should also be avoided during measurements.

Do not touch the device.

• Do not change position or move your wrist or ﬁngers.

• Do not talk.

•

[CAUTION]

Keep away from cellular telephones and other sources of electromagnetic radiation during measurements. Failure to do so could result in blood pressure monitor malfunctioning.
