BASIC PRODUCT INFORMATION

This manual is intended to assist the user in the safe and efficient operation of the Model DS-400 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-400 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.
