1.1. Features of the KL300
The blood-pressure monitor KL300 (with integrated time/date display) is a fully automatic, digital blood-pressure measuring 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 and clinical tested measurement accuracy and has been designed to provide a maximum of user-
friendliness.
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.
1.2. 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 circumstances should you alter the dosages of any drugs prescribed by your doctor.
•
The pulse display is not suitable for checking the frequency of heart pacemakers!
•
In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only be evaluated after
consultation with the doctor.
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 cookers). These can lead to temporary impairment of the
measuring accuracy.
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) minimal (diastolic blood-pressure value).
The blood-pressure values must lie within certain normal ranges in order to prevent particular diseases.
2.2. Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg and/or the systolic blood-pressure is over 160 mmHg.
In this case, please consult your doctor immediately. Long-term values at this level endanger your health due to the associated
advancing damage to the blood vessels in your body.
Should the systolic blood-pressure values lie between 140 mmHg and 160 mmHg and/or the diastolic blood-pressure values lie
between 90 mmHg and 100 mmHg, likewise, please consult your doctor. Furthermore, regular self-checks will be necessary.
With blood-pressure values that are too low, i.e. systolic values under 100 mmHg and/or diastolic values under 60 mmHg, likewise,
please consult your doctor. Even with normal blood-pressure values, a regular self-check with your blood-pressure monitor is
recommended. In this way you can detect possible changes in your values early and react appropriately. If you are undergoing
medical treatment to control your blood pressure, please keep a record of the level of your blood pressure by carrying out regular
self-measurements at specific times of the day. Show these values to your doctor.
Never use the results of your measurements
to alter independently the drug doses prescribed by your doctor.
