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 deter
mined 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 mmH
g over 80 mmHg (120/80), for 
example, your systolic pressure is 120
 mmHg while your diastolic pressure 
is 80 mmHg
.

	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 deter

mine 
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

er disease, arteriosclerosis or other medical conditions, 
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 man y f

actors, including age, 
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 suffer ing from cardiac arrh

ythmia, vascular constriction, liver 
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 tak e y

our blood pressure measurements at the same time and 
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 
• 
						

							5English
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 pr
 ior 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

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 f

eet.
	Precautions	to	Ensure	Safe, 	Reliable	Operation

IMPORTANT: Do not be alarmed by temporarily high or low readings because 
fluctuations in a person’s blood pressure are not uncommon. If possible, 
measure and record your blood pressure at the same time every day, 
and consult your physician if you have questions or concerns.
If abnormal variations in blood pressure are observed in measurement, 
please consult your physician.
