Specifications................................................................... 26 Panasonic Oscillometric Diagnostec™ Wrist Blood Pressure Monitor
Model EW3037 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 left wrist. The device is not intended for use on
infants and children. The device is designed for home use only, not for
ambulatory measurement.
Specification of this device including pulse rate (30 - 160 pulse/min. +/–
5%) are listed in page 26.
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, 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.
Display of Normal (green), Prehypertension (yellow) or Hypertension
(orange) 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 EW3037 is not intended to be a diagnostic device. Contact your
physician if prehypertensive or hypertensive values are indicated.

Important Instructions Before Use
1.Do not confuse self-monitoring with self-diagnosis. Blood pressure
measurements should only be interpreted by a health 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,
liver 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 many factors, 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 suffering from cardiac arrhythmia, 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 take your 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 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
Introduction
Thank you for purchasing the Panasonic Wrist Blood Pressure Monitor
EW3037. 
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 over 80 (120/80), for example, your systolic
pressure is 120 while your diastolic pressure is 80.

IMPORTANT:
•Measure your blood pressure at the same time and under the same
conditions every day if possible. The ideal time to measure your blood
pressure is in the morning immediately after waking up, while you are still
relatively calm. If this is not possible, try to take your blood pressure prior
to breakfast, before you become active.
•Relax and take measurements in a comfortable position.
•Rest for at least 5 minutes before taking a measurement.
•Keep still and do not speak during measurement. Blood pressure can
fluctuate with the slightest change, such as tensing your muscles or
changing your posture.

(NOTE: The time and date of measurements will not
display correctly unless set beforehand.)
1.The  mark will flash after a measurement has
been completed with sounds (Fig. 10-a). 
Press the Memory/Recall button.
2. Memory storage is completed.
•Readings of up to 90 measurements can be stored in
memory with sounds (Fig. 10-c, 10-d). Readings over
the memory capacity will be recorded over the oldest
measurement in memory.
•Readings cannot be saved when a measurement has
been unsuccessful (display of the error mark  for
blood pressure readings). Readings can be saved,
however, when the  mark is displayed for the pulse
rate.Fig. 10-a

Alarm function signals high blood pressure
Blood pressure values for both systolic and diastolic readings are
determined and indicated via a three-color LED system as being within
normal or hypertensive ranges based on definitions and classification of
blood pressure levels by the JNC 7. Moreover, when blood pressure is in the
high range, the reading displayed on screen flashes on and off to alert user.
According to JNC 7 Classification, values consistently in excess of 140 mmH
g
(Sys.) and/or 90 mmHg(Dia.) are considered to constitute high blood pressure.
