Hartmann Veroval BPM25 Instructions For Use Manual page 71

Please note that the pressure build-up in the cuff can lead
to temporary disruption of medical devices being used at the
same time on the same arm.
Do not use the blood pressure monitor together with a high
frequency surgical device.
If an intravenous treatment is being carried out or a venous
catheter is inserted in the arm, blood pressure measurements
can lead to injury. Never use the cuff on the arm to which
these conditions apply.
The function of the arm on which the cuff is place may
become impaired during inflation.
If you are carrying out the measurement on another person,
please ensure that using the blood pressure monitor does not
have a lasting negative effect on the blood circulation.
Taking measurements too often within a short time period
as well as maintaining continuous cuff pressure can disrupt
the blood circulation and cause injury. Please take a break
between measurements. If the monitor malfunctions, remove
the cuff from the wrist.
Do not use the blood pressure monitor on patients with
pre-eclampsia during pregnancy.
Important instructions for self-measurement
Even minor changes in internal and external factors (e.g. deep
breathing, stimulants, talking, excitement, environmental fac-
tors) 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 meas-
urement location and the position of the patient (sitting,
standing, reclining). They are also influenced by physical activ-
ity 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 accu-
racy may also be affected if you have very low blood pressure,
diabetes, circulatory disorders and arrhythmias as well as
chills or tremors.
