BASIC PRODUCT INFORMATION
This manual is intended to assist the user in the safe and efficient operation of the Model DS-137 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".
Indications for Use
The DS-137 system is intended for the non invasive measurement of systolic and diastolic blood pressure and determination of
pulse 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 (8.7 to 12.6 inches). Pressure is measured over a range of 0 to 300
mmHg and pulse rate over a range of 40 to 160 beats/minute.
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.
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. 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.
