BASIC PRODUCT INFORMATION

This manual is intended to assist the user in the safe and efficient operation of Digital Blood Pressure
Monitor DS-1902. The product must be used in accordance with the procedures contained in this manual
and must not be used for purposes other than those described herein. It is important to read and understand
the entire manual. In particular, please read carefully and become familiar with the section entitled "TIPS ON
TAKING YOUR BLOOD PRESSURE".
Indications for Use
The DS-1902 system is intended for the non-invasive measurement of systolic and diastolic blood pressure
and determination of pulse rate in adults, i.e., age 12 and above; this unit is not designed for neonatal use.
Also, an inaccurate reading may result if this instrument is used on a child's arm. Consult your physician if you
wish to take a child's blood pressure. The product is recommended for use by patients with labile blood
pressure or known hypertension in a home care environment as an adjunct to medical management. The
cuff will accommodate an upper arm circumference range of approximately 23 to 43 centimeters. Pressure
is measured over a range of 0 to 300 mmHg and pulse rate over a range of 40 to 160 beats/minute.
Method of Measurement
This product employs the oscillometric method for measurement of blood pressure and pulse rate. The cuff is
connected to the main unit and wrapped around the arm. As START/STOP BUTTON is pressed, the system starts
automatic pressurization, during which measurement of blood pressure is done. Circuits within the cuff sense the
small oscillations in pressure against the cuff produced by the expansion and contraction of the arteries in the arm in
response to each heart beat. Pressurization stops when the cuff is inflated enough to determine diastolic and systolic
blood pressures and air is exhausted from the cuff . The amplitude of each pressure waves is measured, converted
to millimeters of mercury, and displayed on the LCD as a digital value. If the pulse rhythm detected during
measurment was irregular, irregular pulse rate rhythm indication be displayed. A memory circuit stores the 30 most
recent measurement results with date and time for comparison and computes the average value of stored data.
DS-1902 meets the stringent requirements of German Hypertension League to carry its quality
marking.
