GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and eff ective
operation of the automatic digital Device for measurement of blood pressure
and heartbeat rate LD,
(
modifi cation LD51, LD51A, LD51U
)
(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.
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 infl 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. Pumping in is ceased when cuff is adequately
pumped in to determine diastolic and systolic pressure (the amplitude of the
pressure waves is measured, converted into millimeters Hg and shown on the
display as fi gures) after which air is released from cuff . The Device has 2 memories,
by 90 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 specifi ed in Technical Specifi 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
– algorithm for processing the measurement
values with regard to peculiarities of the man’s heartbeat, thus,
ensuring high measurement accuracy.
Scale WHO
– classification 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
.
Electronic automatic pressure release valve out of the all-purpose cuff
of device LD51U ensures optimal pressure release rate on an arm of any
size corresponding to that cuff.
WARNING!
This Device may be used only with cuff s:
- Cuff -LDA, size 25-36 cm (delivered in a set with the LD51 and LD51A),
- Cuff -LDU, size 22-42 cm (delivered in a set with the LD51U).
