What is blood pressure?

The blood pressure of the human body is constantly changing, which is attributed to physical or mental
aspects (e.g. disease, physical exertion, stressful situations, fear, caffeine, nicotine, alcohol etc.). The season,
time of day, cold or heat can also affect one's blood pressure. Please consult your physician for specific infor-
mation about your blood pressure.
Information about the oscillometric measurement method
This blood pressure monitor uses the oscillometric method to measure the systolic and diastolic blood pres-
sure and pulse rate. This method is recommended for persons over the age of 18 years, but not for children
or infants. This device serves to measure the systolic and diastolic blood pressure and heart rate of adults in
a non-invasive manner. The device uses the oscillometric method.

Functional principle

This device uses oscillometric technology with a fuzzy algorithm to measure arterial blood pressure and the
pulse rate. The cuff is secured around the arm and automatically inflated by the air pump. The sensor locat-
ed on the device detects the slightest fluctuations in pressure in the cuff, which result from the expansion
and contraction of the arteries in the arm in response to every heart beat. The amplitude of the pressure
waves is measured, converted to millimeters of mercury and shown as a digital value. Important: This device
is unable to provide reliable measurements if it is stored at temperatures or in the presence of moisture
