Introduction; Your Automatic Blood Pressure Monitor; How Is Blood Pressure Measured; What Is Blood Pressure, And Why Does It Fluctuate - Microlife BP3GQ1-3P Instruction Manual

1. Introduction

1.1. Your automatic blood pressure monitor

Your blood pressure monitor is a fully automatic digital blood pressure
measuring device for use by adults on the upper arm at home or in your
doctor'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.
Before using your blood pressure monitor, please read this instruction
manual carefully and then keep it in a safe place for future reference. If
you have additional questions regarding blood pressure measurements
please contact your doctor.

2. How is blood pressure measured?

2.1. What is blood pressure, and why does it fluctuate?

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.
Your level of arterial blood pressure changes periodically during heart
activity. During the "blood ejection" (Systole), the value is highest
(systolicblood 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.

2.2. Measurement guidelines

Blood pressure is too high if your systolic blood pressure is over 160
mmHg and/or your diastolic pressure is above 100 mmHg, while at rest.
In this case, please consult your physician immediately. Long-term values
at this level endanger your health due to continual damage to the blood
vessels in your body.
If your systolic blood pressure values are between 140 mmHg and 159
mmHg and/or the diastolic blood pressure values are between 90 mmHg
and 99 mmHg, consult your physician. Regular self-checks are necessary.
