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 the heart pulls blood back through it.
Blood pressure is recorded as systolic over diastolic, as shown below.

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

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

Home monitoring may help alleviate the medical phenomena ‘White Coat
Hypertension’ which causes many individuals’ 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 50mmHg 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 determine and diagnose and also
provides you the information when your blood pressure falls or rises to enable
to manage your health between doctor visits.

5. What is the benefit of data transmissible blood pressure monitor?

Without going to a hospital, you can get physician’s advice with data

transmissible blood pressure monitor.
ECHO-FT 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. With the
support of the analyzing program, ECHO-FT tracks your blood pressure
changes sophisticatedly and enables you to realize the characteristics of yours

and control it. Periodically monitored and memorized readings reflect the
cardiovascular state of you under conditions more representative of your
normal daily life-style than those inherent in a clinical environment. It let you
learn when your blood pressure falls or rises. Also it let your physician optimize
the treatment program corresponding your circadian rhythm of blood pressure.
Therefore, it is important to take regular daily monitoring and keep clear
records. ECHO-FT is a time and cost saving healthcare networking instrument.

Thank you for purchasing the ECHO-FT.

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. ECHO-FT is designed to enable a
person who suspects some trouble with blood pressure to check it at home.

Fuzzy logic and Oscillometric method
Your unit employs fuzzy logic method to inflate and an oscillometric for
measurement of blood pressure and pulse, 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 program
This device is data transmissible. You can transmit readings saved in the memory
of the device to your personal computer, and then mail them to your physician to
get advice from her/him at home. ECHO-FT is a time saving device partially
replacing a necessity of your visit to your physician. Additionally the data
transmitted to your PC can be analyzed and tracked sophisticatedly with
analyzing software optionally offered by the manufacturer.

Software ‘Hour 24’
‘Hour24’ is a software for windows. It takes data transmitted from ECHO-FT and
enable to send them to the doctor.
Additionally the data can be analyzed and tracked with it.

Noise detecting
As ECHO-FT is contrived to detect moving or noising during measurement
process and displays it both on the real time and recalled readings on LCD. You
or your physician can determine if the readings are reliable.

coffee, tea, cokes and also smoking can
cause your blood pressure to rise.

Moving or speaking while checking causes

errors.

PREPARATION FOR MEASUREMENT

17

To compare the results, choose the
readings got under the same condition.
(monitoring site, position, time etc.)

Continuous monitoring causes arm
congested and inaccurate readings. Allow
3~5 minutes interval between
measurements.

Take off thick coat, sweater or tight-fit
clothes from the monitoring arm. To fit the
cuff on the naked arm is advised.

When you roll up your sleeve, ensure it
does not constrict the blood flow in your

Remove thick or tight-fit clothes from your upper arm.
Sit on a chair with your feet flat on the floor and place your arm on a table so
that the cuff can position as same level as your heart.

1. Wrapping the cuff

① Securely connect the air tube plug of

the cuff to the jack of main unit.

② Unfold the cuff as shown in the drawing.

③ Wrap the cuff around your upper arm.

Position the cuff hose over your brachial
(forearm) artery and between your middle
and ring fingers when it is extended.

④ Position the lower edge of the cuff is 1 ~ 1½

inches above the elbow joint as shown in

the picture.

⑤ Strain the cuff with 2 fingers space between

the cuff inner-liner and the arm.

⑥ Place your arm at the same level as the heart.

MEASUREMENT

Note

Take off thick coat, sweater or tight-fit clothes from the monitoring arm. If

possible, wrap cuff with direct contact between inner-liner of it and the
skin.

When you roll up your sleeve, ensure it does not constrict the blood

flow in

y

our arm.

25

2. Correct measuring posture

① Please place your arm with the palm facing up on the table. When the table is

too low for your arm to position the heart level, adjust the level off with a
cushion, towel or a similar material.

② For monitoring, sit down comfortably on a chair with your feet flat on the floor

and take deep breaths 5 to 6 times and relax.

3. Measuring method

displayed all symbol in LCD edge and [0] in main
LCD.

Note Sit comfortably on a chair with your feet flat on the floor and

relax before monitoring starts. Monitoring should be taken in a
quiet place.

26

Then [▲] symbol remains on LCD panel coinciding
with a start of pressurization. At this time the number
to show the inflated cuff pressure will increase rapidly
as a normal process and the cuff will tighten as air
enters in it. The value of pressurizing is determined
automatically. Do not move your arm and remain still
until the entire measurement completed.

③ Monitoring is in progress
When the pressurizing is over, [▼] symbol appears

and air is released from the cuff slowly. You can
feel the cuff become less tight gradually.

④ Monitoring will start with deflation and if the pulse is sensed during deflation

[♥] symbol appears and flashes.

⑤ When noise is detected during measurement, [

]
appears on its place on the screen. In case that
you move or speak, [

] is accompanied with
a voice warning as “Don’t move or speak please.”
But monitoring will be continued after a pause.

⑥ When Error occurs due to insufficient inflation,

re-pressurization will be held automatically with a
voice massage as “Can’t measure. We will try again.”

⑦ Display the results
When monitoring is over, the value of systolic and

diastolic blood pressure and pulse will be displayed

Note 1.When noise or movement including talking is sensed during

pressurization, re-pressurization will be held automatically.

2. If a higher inflation is needed in any circumstances, the device re­inflates the cuff up to 30~40㎜Hg higher
