GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and eff ective
operation of the semiautomatic digital Device for measurement of blood pres-
sure and heartbeat rate LD, (modifi cation LD22 (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 under-
stand 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 with Fuzzy
Algorithm and pulse rate measurement. Wrap the cuff around your upper arm
and it starts to be infl ated by bulb. 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.
WARNING!
This Device may be used only with cuff s:
- Cuff -LDA, size 25-36 cm (delivered in a set with the Device).
