GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and effec-
tive operation of the automatic digital Device for measurement of blood
pressure and heartbeat rate LD, modi
fi
cation LD5 (LD5a) (hereinafter – the
“Device”). Use this Device according to the rules described in this Manual.
Operate the Device only as intended. Do not use the Device for any other
purposes. Read and understand the whole Instruction Manual, in particular
“Recommendations on Correct Measurement”.
INDICATIONS FOR USE
Use this Device to measure your systolic and diastolic blood pressure and
heartbeat rate in patients aged from 15. This Device is recommended for
use by persons with unstable blood pressure or known arterial hypertension
at home as an addition to medical surveillance. The cuff is designed for the
upper arm with the circumference approximately from 25 to 36 cm.
OPERATION PRINCIPLE
This Device uses the oscillometric method of blood pressure and pulse
rate measurement. Wrap the cuff around your upper arm and it starts
to be inflated automatically. The sensitive element of the Device feels
the weak pressure oscillations in the cuff generated by widening and
contraction of the brachial artery in response to every heartbeat. The
amplitude of the pressure waves is measured, converted into millimeters
Hg and shown on the display as
fi
gures. The Device is capable to store
in its memory up to 30 sets of measurement values. Remember that the
Device will not maintain the mentioned accuracy of a measurement if it is
used or stored at a temperature or humidity other than those speci
fi
ed in
Technical Speci
fi
cations of this Manual. We are warning about possibility
of mistakes in blood pressure measurement with this Device in persons
with pronounced cardiac arrhythmia. Consult the doctor concerning blood
pressure measurement of your child.
APPLIED NEW LD TECHNOLOGIES
Fuzzy Algorithm
is the algorithm for processing the measurement
values with regard to peculiarities of the man’s heartbeat, thus,
ensuring high measurement accuracy.
Scale WHO
– classi
fi
cation of measurement results according to
recommendation of World Health Organization (WHO).
Indication of arrhythmia
– special symbol «
» on device
display informs about availability of irregular pulse; in this case,
measurement result will be correct.
WARNING!
This Device may be used only with cuff Cuff-LDA, size 25-36 cm
(delivered in a set with the Device).
