GENERAL INFORMATION
This guide is intended to provide the user with the safe and efficient operation of a digital blood pressure monitor for measuring blood pressure
and pulse rate LD, model LD8 (hereinafter: the device). The device should be used in accordance with the rules set forth herein, and should
not be used for purposes other than those described here. It is important to read and understand the entire manual, especially the section
«Recommendations for the correct measurement».
INDICATIONS FOR USE
The device is designed to measure the systolic and diastolic blood pressure and heart rate determination of patients aged 15 years. The device
is recommended for use for patients with unstable blood pressure or known hypertension at home as a supplement to medical supervision. Cuff
fits wrist with a circumference of about 12.5 to 20.5 cm .Pressure is measured in the range from 40 to 260 mm Hg, and pulse rate in the range
from 40 to 160 beats per minute.
PRINCIPLE OF OPERATION
The device uses the oscillometric method for measuring blood pressure and pulse rate. The cuff is wrapped around the wrist and inflated
automatically. The sensitive element of the device detects weak pressure oscillations in the cuff, made expansion and contraction of arteries in
response to each heart beat. The amplitude of the pressure wave is measured, converted to millimeters of mercury and displayed as a digital
value. The device has a memory cell 90 to store the measurement results.
NOTE: The device can not provide the specified accuracy if it is used or stored at a temperature or humidity other than specified in the
«Specifications» section of this manual. Warning about possible errors in the measurement of blood pressure using the device in patients with
severe arrhythmia. Consult your physician about blood pressure measurement in children.
