1. Introduction
1.1.Features of your Microlife automatic blood pressure monitor,
(model #BP3AC1-1PC)
Your Microlife blood pressure monitor with MAM (microlife Average Mode) Technology,
Irregular Heartbeat Detection, and PC Link Blood Pressure Analyzer capabilities (software
and USB cable included in 3AC1-PC and 3AC1-PCCOS) is a fully automatic digital blood
pressure measuring device for use by adults on the upper arm at home or in your doc-
tor’s/nurse’s office. It enables very fast and reliable measurement of the systolic and dias-
tolic blood pressure as well as the pulse by way of 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 pressure
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 electro-
magnetic 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/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 frequency of the heart (Pulse), as well as the width of
circulatory blood vessels is altered. Blood vessel width is effected 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 pressure value).
Blood pressure values must lie within certain normal ranges in order to prevent particular
diseases.
