1.1.Features of your Microlife automatic blood pressure monitor,
model # 3BT0-AP
Your Microlife blood pressure monitor is a fully automatic digital blood pressure
measuring device with an integrated Irregular Heartbeat Detector, 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 the systolic and diastolic 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.

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
