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.

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.

PRECAUTIONS FOR USE

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.

BATTERY INSTALLATION

1 Open the battery cover.

2 Install an “AA” type battery into the compartment. Make sure that the polarities correspond to the (+) and (-) marks indicated inside of the comartment.

3 Close the battery compartment cover.

CAUTION!

Do not use rechargeable batteries.

1

2 battery replacement indication

Replace the battery when the battery replacement indication appears on the display or nothing is displayed even if POWER BUTTON is depressed.

Use alkaline battery to increase battery life. Use of regular Carbon-Zinc battery will necessitate more frequent replacement.

Since neither the device or batteries are household waste, follow your national/local recycling rules and dispose of them at appropriate collection sites.

CORRECT MEASURING POSTURE

Sit at the table and let the table support your arm as you take the blood pressure measurement.

Make sure that the measurement location on the upper arm is at approximately the same height as the heart, and that the forearm is extended naturally on the table and does not move.

You may lie on your back and take the measurement. Look at the ceiling, stay calm, and do not move your neck or body during the measurement. Again, make sure that the measurement location on the arm is at approximately the same height as the heart.

WRAPPING THE CUFF

1 With the tube of the cuff positioned in the direction of the fingertips, place the cuff on your left arm.

2 Wrap the cuff around the arm with the edge of the cuff approximately 1 inch (2.5 cm) above the elbow.

3 Press the surface of the cuff to make sure that it is attached securely.

When wrapping the cuff, wrap it loosely enough around the arm so that two fingers can be placed between the cuff and the arm. If the cuff is wrapped more tightly or loosely than this, inaccurate blood pressure readings may result.

If you are wearing a shirt that might restrict circulation in your upper arm or you roll your sleeve up over the upper arm, the blood flow will be restricted, preventing accurate measurement.
