Warning:
This system may fail to yield specified measurement accuracy if operated or stored in
temperature or humidity conditions outside the limits stated in the specifications section of this
manual.
Warning:
This product may contain a chemical known to the state of California to cause cancer,
birth defects, or other reproductive harm.
Caution:
The standard material used is latex-free.
Attention:
Self-measurement means control, not diagnosis or treatment. Unusual values must
always be discussed with your doctor. Under no circumstances should you alter the dosages of any
drugs prescribed by your doctor.
Attention:
The pulse display is not suitable for checking the frequency of heart pacemakers!
Attention:
In cases of irregular heartbeat, measurements made with this instrument should only be
evaluated after consultation with your doctor.
NOTE:
To obtain the greatest accuracy from your blood pressure instrument, it is recommended that
the instrument be used within a temperature range of 50°F (10°C) to 104°F (40°C), with a relative
humidity range of 15-85% (non-condensing).
3. ABOUT BLOOD PRESSURE
3.1. What is Blood Pressure?
Simply put, arterial blood pressure is the force of blood exerted against the walls of the
arteries. There are two components to blood pressure — systolic and diastolic pressure.
Systolic, the higher pressure, occurs during contraction of the heart. Diastolic, the lower
pressure, occurs when the heart is at "rest."
Your level of blood pressure is determined in the circulatory center of the brain and adjusts
to a variety of situations through feedback from the nervous system. To adjust blood
pressure, the strength and frequency of the heart (Pulse), as well as the width of circulatory
blood vessels is altered. Blood vessel width is affected by fine muscles in the blood vessel
walls. Blood pressure is traditionally measured in millimeters of mercury (mmHg).
It is recorded as systolic/diastolic. For example a systolic of 120 and diastolic of 80 would
be recorded 120/80.
Blood pressure is a dynamic vital sign - one that changes constantly throughout the day. A
person's "resting" blood pressure is the pressure that exists first thing in the morning while
a person is still at rest and before consumption of food or drink.
3.2. What is a Normal Blood Pressure?
A systolic pressure of less than 120mmHg and a diastolic pressure of under 80mmHg are
recognized as normal by the Joint National Committee on Prevention, Detection, Evaluation,
and Treatment of High Blood Pressure, 2003.
NOTE:
Blood pressure does increase with age, so you must check with your doctor to find
out what is “normal” for you! Even with normal blood pressure values, a regular self-check
with your blood pressure monitor is recommended. You can detect possible changes in your
values early and react appropriately. If you are undergoing medical treatment to control your
blood pressure, keep a record of values along with time of day and date. Show these values
to your doctor. Never use the results of your measurements to independently alter the drug
doses prescribed by your doctor.
