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 LD30 (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
in
fl
ated 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 has 2 memories, by 60 cells, for storage
of measurement results. 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.
WARNING!
This Device may be used only with Cuff-LDA, size 25-36 cm
(delivered in a set with the Device).
