BASIC PRODUCT INFORMATION

This manual is intended to assist the user in the safe and efficient operation of the Model DS-1873 Digital Blood Pressure Monitor. 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".
The user is cautioned that the system may fail to yield specified measurement accuracy if operated or stored in temperature or humidity
conditions outside the limits stated in the specifications section of this manual. 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.
Indications for Use
The DS-1873 system is intended for the non invasive measurement of systolic and diastolic blood pressure and determination of heart rate
in adult patients, i.e., age 15 and above. 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 22 to 32 centimeters. Pressure is measured over a range of 0 to 300 mmHg and heart 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 heart rate. The cuff is connected to the main unit
and wrapped around the arm. As ON/OFF BUTTON is pressed, the system starts automatic pressurization. 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. The amplitude of each pressure waves is measured, converted to millimeters of mercury, and displayed on the LCD as a digital
value. A memory circuit stores the 30 most recent measurement results for comparison.
