Getting to Know Your
Blood Pressure Monitor
Blood pressure monitors use the oscillometric method of
measuring blood pressure. The monitor can detect the
blood's movement through the brachial artery and convert
it into a digital reading. The monitor is easy and simple to
use and does not require a stethoscope.
This monitor has many useful features such as a speaking
function with volume adjustment, 2 users that can save 120
measurements each, a cuff
self-check indicator, average value indicator, irregular
heartbeat indicator, WHO indicator, and external power
socket support.

Information on
Blood Pressure
Your blood pressure level is determined in the circulatory
center of your brain and adjusts to a variety of situations
through feedback from the nervous system. To adjust
blood pressure, the strength and speed of your heart (your
pulse) and the width of your circulatory blood vessels are
altered. Blood vessel width is controlled by fine muscles in
the blood vessel walls. Your level of arterial blood pressure
changes periodically during heart activity. During "blood
ejection" from the heart (systole), pressure is highest
(systolic blood pressure value / SYS). At the end of the
heart's "rest period" (diastole), pressure is lowest (diastolic
blood pressure value / DIA). Blood pressure values must lie
within certain normal ranges in order to prevent particular
diseases.
