1. Introduction

1.1. Your Automatic Blood Pressure Monitor

Thank you for purchasing a fully automatic blood pressure
monitor. Your monitor is designed to provide fast and reliable
digital readings of your pulse, and systolic / diastolic blood
pressure using the oscillometric method on your upper arm. It
offers clinically proven accuracy and has been designed to be
user friendly.
Before using your blood pressure monitor, please read this
instruction manual carefully to ensure correct use. 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 (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.

2.2. Measurement guidelines

Blood pressure is very 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
