1. Introduction
1.1. Features of your Automatic Blood Pressure Monitor
Your blood pressure monitor with Microlife Averaging Mode, Irregular Heartbeat
Detection, and PC Link Blood Pressure Analyzer Software is a fully automatic digital
blood pressure measuring device for use by adults on the upper arm at home or in
your doctor’s/nurse’s office. It enables very fast and reliable measurement of systolic
and diastolic blood pressure as well as pulse through the oscillometric method. This
device offers clinically proven accuracy and has been designed to be user friendly.
Before using, please read this instruction manual carefully and then keep it in a safe
place. Please contact your doctor for further questions on the subject of blood pres-
sure and its measurement.
Attention!
1.2. Important information about self-measurement
• 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.
•
The pulse display is
not
suitable for checking the frequency of heart pacemakers!
•
In cases of irregular heartbeat, measurements made with this instrument should
only be evaluated after consultation with your doctor.
Electromagnetic interference:
The device contains sensitive electronic components. Avoid strong electrical or elec-
tromagnetic fields in the direct vicinity of the device (e.g. mobile telephones,
microwave ovens). These can lead to temporary impairment of the measuring accuracy.
2. Important Information on Blood Pressure and its Measurement
2.1. How does high or low blood pressure arise?
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 speed of the heart (Pulse), as well as the width of
circulatory blood vessels is 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
the “blood ejection” (Systole) the value is highest (systolic blood pressure value). At
the end of the heart’s “rest period” (Diastole) pressure is lowest (diastolic blood pres-
sure value).
