INTRODUCTION
To achieve the maximum benefit from your blood pressure
monitor, we recommend that you first consult with
your physician or trained healthcare professional.
Thank you for purchasing a MABIS Dot Matrix Automatic Wrist
Digital Blood Pressure Monitor. With proper care and use, your
monitor will provide you with many years of reliable readings.
The method of measurement that your Wrist Monitor uses is called
the oscillometric method. The monitor detects your blood’s movement
through the artery in your wrist and converts the movements into a
digital reading. The oscillometric method does not require a stetho-
scope, making the monitor easy to use. The preformed cuff requires
little effort to apply and is comfortable to wear.
Your Wrist Monitor is specially enhanced with on-screen instructions
in five different languages. Up to 30 readings per memory bank (60
total measurements) can be viewed on charts or graphs including an
average of the readings stored. Your monitor is also designed to
take measurements quickly and deflate even faster for increased
comfort.
Clinical research has proven a direct relationship between blood
pressure in the wrist and blood pressure in the arm. Because the
arteries in the wrist and the arm are connected, changes in wrist
blood pressure reflect changes in arm blood pressure. Consistent
wrist measurements will provide you and your physician with an
accurate indication of change in your true blood pressure.
Blood pressure readings determined with this device are equivalent
to measurements obtained by a trained observer using the
cuff/stethoscope auscultation method, within the limits prescribed by
the American National Standard for Electronic or Automated
Sphygmomanometers.
This monitor is designed to function in accordance with the specifications
for persons with common arrhythmias, such as arterial or ventricular
premature beats or arterial fibrillation.

GENERAL BLOOD PRESSURE
INFORMATION
What is Blood Pressure?
Blood pressure is the pressure that is exerted by blood flowing
against the walls of the blood vessels throughout your body.
Your heart, which is the center of the circulatory system, provides
the force for the blood to flow or circulate. When your heart contracts
or beats, the blood is forced through the blood vessels increasing
the pressure. This is the highest pressure in the cycle or what is
referred to as SYSTOLIC blood pressure. In between beats, your
heart relaxes and your blood pressure decreases. This is referred
to as DIASTOLIC blood pressure.
This complete series of events, which occurs in a single heartbeat, is
known as the CARDIAC CYCLE.
Your Wrist Monitor will automatically read your blood pressure
and display both systolic and diastolic readings on the screen.
Your systolic will be
(systolic)
positioned as the upper
number and the diastolic
reading will be the
120
80
(diastolic)
lower number.
Blood pressure is measured in millimeters (mm) of mercury (Hg)
and is generally recorded with the systolic pressure (120) listed
first and the diastolic pressure (80) listed second. The numbers are
typically separated by a slash mark (/ ) as shown above.
Both pressure readings, the SYSTOLIC and DIASTOLIC, are necessary
for a physician to evaluate the status of a patient’s blood pressure.
Please contact your physician for specific information
regarding your own blood pressure.

Why Monitor Your Blood Pressure at Home?
Many people experience “White Coat Syndrome”, which is a
temporary elevation of blood pressure during a visit at their
physician’s office. Although only temporary, it can cause
blood pressure to rise and give a false indication of a person’s
true blood pressure.
Whether or not you experience “White Coat Syndrome”, home
blood pressure monitoring provides:
1) The opportunity to supplement your physicia n’s
office measurements.
2) An accurate indication of any change.
3) A record to assist your physician in evaluating your health
and making important decisions.
4) Consistent, daily measurements of your blood pressure.
NOTE: The variations in your individual
readings should only be interpreted by your
physician or trained healthcare professional.
What Influences Blood Pressure?
Many factors such as genetics, age, sex, altitude, physical activity,
anxiety, muscular development, certain medications or even the
time of day can influence blood pressure. Influences such as
sleep or relaxation decrease blood pressure, while anxiety or
exercise increase blood pressure.

VARIATIONS IN BLOOD PRESSURE
Blood pressure is influenced by many factors and can change
from moment to moment. Normally, blood pressure is lowest
during sleeping periods and rises during the day. The graph
below represents variations in blood pressure shown over a
day with measurements taken every 5 minutes.
The dotted line represents the sleep period. The rise in blood
pressure at 1pm (A in the graph) corresponds to a stressful
occurrence and at 7 pm (B in the graph) a period of exercise.
