Taking measurements too often within a short time period as well as main-
taining continuous cuff pressure can disrupt the blood circulation and cause
injury. Please take a break between measurements and do not bend or fold
the air tube. If the monitor malfunctions, remove the cuff from the arm.
Do not use the blood pressure monitor on patients with pre-eclampsia dur-
ing pregnancy.
Important instructions for reading your own blood pressure
Even minor changes in internal and external factors (e.g. deep breathing, stim-
ulants, talking, excitement, environmental factors) can lead to fluctuations in
blood pressure. This explains why anomalous values are often measured by a
doctor or pharmacist.
Measurement results depend fundamentally on where the reading is taken
and the position of the patient (sitting, standing, reclining). They are also
influenced by physical activity and physiological preconditions of the patient,
for example. For comparable values, carry out the measurement in the same
location and the same position.
Diseases of the cardiovascular system can lead to erroneous readings or lower
the accuracy of the measurement. The accuracy may also be affected if you
have very low blood pressure, diabetes, circulatory disorders and arrhythmias
as well as chills or tremors.
Consult your doctor before measuring your own blood pressure if ...
you are pregnant. Blood pressure may vary during pregnancy. Regular blood
pressure monitoring is particularly important if you have high blood pressure
because elevated values may affect foetal development. Check with your doctor
in any case to find out if and when you should measure your own blood pres-
sure, especially if you suffer from pre-eclampsia.
you suffer from diabetes, liver disorders or congestion of blood vessels (e.g.
arteriosclerosis, peripheral arterial occlusive disease) because anomalous
measured values may occur in such cases.
you suffer from certain blood diseases (e.g. haemophilia) or severely impaired
blood flow or if you take blood-thinning drugs.
