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 15-90% relative humidity.
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.
