ABOUT BLOOD PRESSURE

1. What is blood pressure?

Blood pressure refers to the force or pressure exerted on the artery vessel
when blood flows through them. In order to allow the blood to supply nutrition
and oxygen to every organ and corner of the body, a certain level of pressure
is necessary and it comes from the each time the heart beats or contracts.
The heart activity is broken down into two phases called Systole and Diastole.
Systolic is the pressure to send blood out into the body and Diastolic is the
pressure creating as the heart pulls blood back through it.
Blood pressure is recorded as systolic over diastolic, as shown below.

115/75

systole occurs diastole occurs
during the contraction during the relaxation
and empting of the heart and filling of the heart

2. What makes my blood pressure fluctuate?

Blood pressure changes in response to many factors.
These factors include changing in the temperature and humidity, physical
exercise, restlessness due to stress, fear, anxiety, anger, food and an
individual’s physical condition.

Blood pressure constantly fluctuates during of a day, so that monitoring

Note

should be done at least three times and determined. Occasional high or

low readings do not mean your monitor is malfunctioning or you are ill.
The important thing is that you have information to talk with your doctor
about normal and abnormal results corresponding your circadian rhythm.

4. Why do I have to check blood pressure at home?

Home monitoring may help alleviate the medical phenomena ‘White Coat
Hypertension’ which causes a sensitive individual blood pressure to be higher
when taken in a medical office setting. The elevation of it may be due to
several factors, including stress, nervousness, or increased sympathetic
activity associated with the clinical environment. It may cause your blood
pressure to rise about 20 to 30mmHg higher than usual. When monitoring at
home, you may get a truer indication of your blood pressure in a usual,
relaxed state. Regular home monitoring provides you a valuable over time
readings to give to your physician to diagnose and optimize the treatment
program corresponding your circadian rhythm of blood pressure. It also
provides you the information when your blood pressure falls or rises to enable
to manage your health. Therefore, it is important to take regular daily home
monitoring and keep clear records.

5. What is benefit of ECHO-H User-set inflation level monitor use?

ECHO-H allows that user can set up the inflation level corresponding the blood
pressure of user-self. This function is ideal for the hypertensive while other
kinds of pressurization method are more suitable to the person who is able to
estimate own blood pressure or under treatment. For a correct monitoring, the
pressurization need 30㎜Hg higher than your estimated blood pressure.
Therefore the hypertensive may have frequently experienced re-pressurization
during monitoring with the monitor employed those methods. In case of
excessive hypertension or a feeble pulse, it is possible to experience it over 2
times a monitoring. That will affect your emotion, blood vessel and eventually
monitoring results.
ECHO-H, the monitor of user-set inflation excludes the necessity of re­pressurization during monitoring of the hypertensive and makes it convenient
and correct with the single pressurization trial.

6. What is the benefit of date and time recorded wrist monitor use?
There is no need to remember monitoring date and time if the device

automatically records them. As ECHO-H is built-in calendar and clock that
inconvenience is not any more.

These are more helpful to the device having big memory capacity.

7. What is the benefit of ECHO-H data transmissible wrist blood pressure monitor
use?

Without going to hospital, you can have physician’s advice with data
transmissible blood pressure monitor.
ECHO-H is a Home to Hospital bi-directional networking blood pressure
monitor that you can transmit saved data from the device to your personal
computer through interface then send your physician them. Your physician will
read those to find health problems and give proper advice you through
computer network. With the support of the analyzing program, ECHO-H tracks
your blood pressure changes sophisticatedly and enables you to realize the
characteristics of yours and control it.

ECHO-H is a time and cost saving

healthcare networking watch-type instrument.

INTRODUCTION

Thank you for purchasing the ECHO-H.
Intended use
This home blood pressure monitoring device is indicated for use in the noninvasive
measurement of systolic and diastolic blood pressure and heart rate in adult age
18 and over, in a home care environment. This model is designed to enable a
person who suspects some trouble with blood pressure to check it at home.
User-set inflation and Oscillometric method
Your unit employs a user-set inflation and an oscillometric method. The user can
decide its inflation level corresponding the characteristics of the user’s blood
pressure. Oscillometric for measurement of blood pressure and heart rate, which
refers to check blood pressure by measuring oscillation in the cuff while the artery
of the arm oscillate reflecting contracts and relaxes every heart beat.
Data transmissible and analyzing software
This device is data transmissible. You can transmit readings saved memory of the
device to your personal computer then mailing to your physician and get advice
about it from her/him at home. ECHO-H is a time saving device partially replacing
a necessity your visit to your physician. Additionally the data transmitted to your
PC can be analyzed and tracked sophisticatedly with analyzing program optionally
offered by manufacturer.
Voice massage
Makes you monitor blood pressure easily and know the result clearly without third
person’s help especially for the elderly.
Noise detecting
As ECHO-H is contrived to detect moving or noising during measurement and
display it both on the real time and recalled reading on LCD, you and your
physician can determine if the readings are reliable.
Memory feature
It has 64 reading memory capacity recorded monitoring date and time supporting
built-in calendar and clock which are input them automatically to each reading.
Accuracy
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.
