GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and effective
operation of the automatic digital Device for measurement of blood pressure
and heartbeat rate LD, modi
fi
cation LD3 (LD3a) (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 is capable to store in its memory up to 90 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.
WARNING!
This Device may be used only with cuff Cuff-LDA,
