Principle Of Operation; Tips On Taking Blood Pressure Measurement - Henry Schein 9008181 Instrucciones De Uso

2
GENERAL
This instruction manual is intended to assist the user for safe and ef-
ficient operation of the automatic digital blood pressure monitor (he-
reinafter: device) model LD7. The device must be used in accordance
with the procedures described in the manual. It is important to read
and understand the entire manual, especially the section "Tips on ta-
king blood pressure measurement". This device is intended for the
non-invasive measurement of systolic and diastolic arterial blood
pressure and pulse rate in adults (age 15 and above). Consult the phy-
sician if measurement is taken in children or persons with arrhythmia
as errors may occur.

PRINCIPLE OF OPERATION

This device adopts the oscillometric technology with Fuzzy Algorithm
measuring the arterial blood pressure and pulse rate. The cuff is wrap-
ped around the arm and automatically inflated by the air pump. The de-
vice sensor catches weak fluctuation of the cuff pressure in the cuff
produced by extension and contraction of the artery of the arm in re-
sponse to each heartbeat. The amplitude of the pressure waves is mea-
sured, converted in millimeters from the mercury column, and is
displayed in digital value. Annotation: This device cannot provide rea-
sonable accuracy if used or stored in the temperature or humidity bey-
ond the range stated in the section "SPECIFICATIONS" of this manual.
NEW TECHNOLOGIES USED
FUZZY algorithm takes into account the uniqueness of individual
heartbeats, which provides higher accuracy of measurement.

TIPS ON TAKING BLOOD PRESSURE MEASUREMENT

1. Arterial blood pressure is subjected to sharp fluctuations. The level
of the arterial blood pressure depends on many factors. Generally
arterial blood pressure is lower in summer and higher in winter.
