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.
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-400 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 8.7 to 12.6 inches (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. Circuits within the monitor 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 wave is measured,
converted to millimeters of mercury, and displayed on the LCD as a digital value. Memory circuit stores the 30 most recent measurement results for comparison.
Accuracy was evaluated during clinical studies in which results with the DS-400 system were compared with simultaneous auscultatory measurements obtained with a standard sphygmomanometer. In these
studies, the onset of the fourth (or fifth) Korotkoff sound was taken as the diastolic pressure for the purpose of determining overall efficacy. A copy of this study is available from the manufacturer on request.
To insure that accuracy is maintained, compare readings obtained with the DS-400 system with values measured by a trained observer using a manual sphygmomanometer at least every 6 months.
Blood pressure measurements determined with this device are equivalent to those obtained by a trained observer using the cuff stethoscope auscultation method, within the limits prescribed by the
American National Standard, for Electronic or Automated Sphygmomanometers.
The DS-400 system has the ability to function according to its specifications in the presence of common arrhythmias such as atrial or ventricular premature beats or atrial fibrillation.
CAUTION! Do not use cuffs other than those manufactured for this product.
Do not use this instrument without consultation with your doctor if you are under dialysis therapy or on anticoagulants, antiplatelets or
steroids. Use of this instrument under such conditions could cause internal bleeding.
To avoid any possibility of accidental strangulation, keep this unit away from children and do not drape AIR HOSE around your neck.
For specific information on your blood pressure, contact your physician. Never make any judgment on measurement results on your own.
Use of this device in areas near portable phones, microwave ovens or other devices with strong electromagnetic field may cause malfunctions.
