• High Precision Gauge: Constructed with durable and lightweight ABS Plastic, pressure tested for maximum repeat accuracy. Features a clinical accuracy of +/- 3 mmHg with a 0-300 mmHg manometer. Includes a built-in basket for convenient storage of the cuff and bulb.
• Inflation Bulb with Air Release Valve: The inflation bulb is made of crack-resistant and non-sticking rubber. The air release valve is chrome-plated to prevent corrosion. The device incorporates a dual-tube bladder for efficient air release during measurement.
• Cotton Cuff with Extra Wide Velcro Fasteners: Designed with a special cotton cuff for patient comfort and pain-free use. Equipped with extra wide Velcro fasteners to ensure a firm grip and easy application across various arm sizes.

Setup

Before taking a measurement, ensure the device is properly assembled and positioned. The EL-430 is a clock/desk type unit, designed for stable placement during use.

1. Unpack Components: Carefully remove the sphygmomanometer, cuff, and inflation bulb from the packaging.
2. Connect Cuff and Bulb: Ensure the cuff and inflation bulb are securely connected to the gauge via their respective tubes. The dual-tube bladder should be correctly attached.
3. Position the Device: Place the main gauge unit on a stable, flat surface, such as a desk or table, at approximately heart level. The integrated basket can be used to keep the cuff and bulb organized.
4. Patient Preparation: The patient should be seated comfortably with their arm resting on a flat surface, palm facing upwards. Ensure the arm is relaxed and at heart level. Avoid talking or moving during the measurement.

Operating Instructions: Measurement Procedures

Follow these steps for accurate blood pressure measurement:

1. Cuff Placement and Stethoscope Positioning: Wrap the cuff firmly around the upper arm, ensuring it is snug but not too tight. The lower edge of the cuff should be about 1 inch (2-3 cm) above the elbow joint. Place the stethoscope head over the main artery (brachial artery), which is typically found on the inner side of the arm, underneath the artery mark of the cuff.
2. Inflation: With the air release valve completely closed, press the inflation bulb repeatedly and continue pumping until the gauge reads a value 20-30 mmHg above your normal systolic blood pressure. If you do not know your normal systolic pressure, inflate to approximately 180-200 mmHg.
3. Listening and Recording Systolic Pressure: Slowly open the air release valve to deflate the cuff at a rate of 2-3 mmHg per second. Listen carefully through the stethoscope. The first distinct, rhythmic sound you hear (Korotkoff sound) indicates the systolic pressure (the upper number). Note the reading on the gauge at this exact moment.
4. Listening and Recording Diastolic Pressure: Continue to slowly deflate the cuff. The point at which the Korotkoff sounds completely disappear indicates the diastolic pressure (the lower number). Note this reading on the gauge. If the sounds become muffled but do not disappear, the muffled sound point can be considered the diastolic pressure.

Understanding Blood Pressure Readings

Refer to the chart below for general blood pressure categories. Consult a healthcare professional for interpretation of your readings and personalized advice.

DO NOT ATTEMPT A READING...

1. Within 1 hour of food intake.
2. Immediately after a tea, coffee, or a smoke.
3. Within 20 minutes of taking a bath.
4. While talking or moving your hand/fingers.
5. When climate is very cold.
6. When bladder is full or you feel like discharging urine.

Maintenance and Care

Proper maintenance ensures the longevity and accuracy of your sphygmomanometer.

• Cleaning: Wipe the gauge and inflation bulb with a soft, dry cloth. The cuff can be cleaned with a damp cloth and mild soap, then air-dried completely. Do not immerse the gauge or bulb in water.
• Storage: Store the device in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity. Utilize the gauge's integrated basket for organized storage of the cuff and bulb.
• Avoid Dropping: The gauge is a precision instrument. Avoid dropping or subjecting it to strong impacts, as this can affect its calibration and accuracy.
• Calibration: Aneroid sphygmomanometers should be calibrated periodically (e.g., annually) by a qualified technician to ensure continued accuracy.

Troubleshooting

If you encounter issues with your ELKO EL-430, refer to the following common problems and solutions:

• Cuff does not inflate or inflates slowly:
  • Ensure the air release valve is fully closed before pumping.
  • Check all connections between the bulb, cuff, and gauge for leaks or loose fittings.
  • Inspect the cuff and tubing for any punctures or damage.
• Gauge needle does not return to zero:
  • This may indicate a need for recalibration. Contact customer support or a qualified technician.
  • Ensure no pressure remains in the cuff or tubing.
• Inconsistent or inaccurate readings:
  • Ensure proper cuff size and placement.
  • Verify the patient is relaxed, seated correctly, and not moving or talking during measurement.
  • Check for proper deflation rate (2-3 mmHg per second).
  • Consider professional calibration if issues persist.
