Electromagnetic Interference; How Does High/Low Blood-Pressure Arise - Medel ELITE Instrucciones De Uso

1. INTRODUCTION
MEDEL ELITE blood-pressure monitor is a automatic, digital blood-pressure meas-
uring device for use on the upper arm, which enables very fast and reliable
measurement of the systolic and diastolic blood-pressure as well as the pulse
frequency by way of the oscillometric method of measuring. The device offers a
very high measurement accuracy and has been designed to provide the maxi-
mum user-friendliness.
ATTENTION!
Before using, please read through this instruction manual carefully and then keep
it in a safe place. For further questions on the subject of blood-pressure and its
measurement, please contact your doctor.
ATTENTION!
1.1 Important information about self-measurement
• Do not forget: self-measurement means control, not diagnosis or treatment.
Unusual values must always be discussed with your doctor. Under no circum-
stances should you alter the dosages of any drugs prescribed by your doctor.
• The pulse display is not suitable for checking the frequency of heart pacemak-
ers! In cases of cardiac irregularity (I.H.B.), measurements made with this
instrument should only be evaluated after consultation with the doctor.

1 .2 Electromagnetic interference

The device contains sensitive electronic components (Microcomputer). Therefore,
avoid strong electrical or electromagnetic fields in the direct vicinity of the device
(e.g. mobile telephones, microwave ovens). These can lead to temporary impair-
ment of the measuring accuracy.
2. IMPORTANT INFORMATION ON THE SUBJECT OF
BLOOD PRESSURE AND ITS MEASUREMENT

2.1. How does high/low blood-pressure arise?

The level of blood-pressure is determined in a part of the brain, the so-called
circulatory centre, and adapted to the respective situation by way of feedback
via the nervous system. To adjust the blood-pressure, the strength and frequency
of the heart (Pulse), as well as the width of circulatory blood vessels is altered.
The latter is effected by way of fine muscles in the blood-vessel walls. The level
of arterial blood-pressure changes periodically during the heart activity: during
the 'blood ejection' (Systole) the value is maximal (systolic blood-pressure value),
at the end of the heart's 'rest period' (Diastole) it is minimal (diastolic blood-
pressure value). The blood-pressure values must lie within certain normal ranges
in order to prevent particular diseases.
