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 LD23, LD23A, LD23L) (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 with Fuzzy
Algorithm 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. 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.
Indication of arrhythmia
– special symbol «
» on Device display
informs about availability of irregular pulse (for LD23, LD23A).
WARNING!
This Device may be used only with cuff s:
- Cuff -LDA, size 25-36 cm (delivered in a set with the LD23 and LD23A)
- Cuff -LDA2, size 32-43 cm (delivered in a set with the LD23L).
