Description

The Omron Automatic Blood Pressure Monitor HEM-8712 is designed with convenience and accuracy in mind. The device comes with a contoured cuff that fits standard to large arms, ensuring a comfortable fit for most users. The monitor itself is compact and lightweight, making it easy to store and transport. The HEM-8712 also includes a blood pressure classification indicator, which helps users understand their readings based on the World Health Organization's classification chart. This feature is particularly useful for those who are new to monitoring their blood pressure.

Using the Monitor

Applying the Arm Cuff

Remove tight-fitting clothing or tight rolled up sleeve from your upper arm. Do not place the arm cuff over thick clothes

1. Plug the arm cuff into your monitor by inserting the air plug into the air jack securely until it clicks.

2. Put your arm through the cuff loop.
   The bottom edge of the arm cuff should be 1 to 2 cm above the elbow. Marker (arrow under the air tube) is centred on the middle of your inner arm.

   

3. Close the fabric fastener FIRMLY

   

Notes

• When you take a measurement on the right arm, the air tube will be at the side of your elbow. Be careful not to rest your arm on the air tube.
• The blood pressure can differ between the right arm and the left arm, and therefore also the measured blood pressure values can be different. OMRON recommends to always use the same arm for measurement. If the values between both arms differ substantially, please check with your doctor which arm to use for your measurement

How to Sit Correctly

To take a measurement, you need to be relaxed and comfortably seated at comfortable room temperature.

• Sit in a chair with your legs uncrossed and your feet flat on the floor.
• Sit with your back and arm being supported.
• The arm cuff should be placed on your arm at the same level as your heart .

Taking a Reading

Notes

• To cancel a measurement, press the START/STOP button to release the air in the arm cuff.
• Remain still and do not talk while taking a measurement.

1. Press the START/STOP button.
   The arm cuff will start to inflate automatically.

   

   If your systolic pressure is more than 210 mm Hg
   After the arm cuff starts to inflate, press and hold the START/STOP button until the monitor inflates 30 to 40 mmHg higher than your expected systolic pressure.

   Notes

   • The monitor will not inflate above 299 mmHg.
   • Do not apply more pressure than necessary.

   Note: Wait 2-3 minutes before taking another blood pressure measurement. Waiting between readings allows the arteries to return to the condition prior to taking the blood pressure measurement.

   WARNING: Always consult your doctor. Self-diagnosis of measurement results and self-treatment are dangerous.

   Cuff Wrapping Guide: The Cuff Wrapping Guide is a unique feature that indicates if the cuff is not wrapped tightly enough around the arm. Even when the appears on the display, a blood pressure reading will be taken.

   Note: This reading is NOT reliable due to the incorrect wrapping of the cuff. Please wrap the cuff again, taking care to wrap it correctly and take the measurement again. When the is displayed, the cuff is correctly wrapped tightly enough on the arm and the reading is accurate and reliable.

2. Remove the arm cuff

3. Press the START/STOP button to turn the monitor off.
   The monitor automatically stores the measurement in its memory. It will automatically tum off after 2 minutes.

Important:

If your systolic or diastolic pressure is outside the standard range, the heartbeat symbol will blink when the measurement result is displayed. Recent research suggests that the following values can be used as a guide to high blood pressure for measurements taken at home.

Systolic Blood Pressure: Above 135 mmHg
Diastolic Blood Pressure: Above 85 mmHg

This criteria is for home blood pressure measurement

If you move during measurement, the movement error symbol () will appear on the display. Keep still and repeat the measurement

Using the Memory Function

The monitor automatically stores the last measurement values (blood pressure and pulse rate).

To View the Readings Stored in Memory

1. Press and hold the START/STOP button for more than 5 seconds.
   • The last measurement value is displayed along with the memory symbol.
     Notes
     • If your systolic or diastolic pressure is outside the standard range, the heartbeat symbol will blink when the measurement result is displayed.
     • The cuff wrapping guide result appears on the display with the measurement values.
     • If there are no measurements results stored in the memory, the screen to the right is displayed

2. Press the START/STOP button to turn the monitor off. It will automatically turn off after 2 minutes.

To Delete the Values Stored in Memory
Press and hold the START/STOP button for more than 15 seconds.

Setup Guide

Setting up and using the Omron HEM-8712 is straightforward. Here’s a step-by-step guide:

1. Place the cuff around your upper arm at heart level.
2. Sit comfortably and relax your arm on a table or flat surface.
3. Press the start button; the monitor will inflate the cuff automatically.
4. Wait for the measurement to complete; the device will deflate the cuff and display your blood pressure and pulse rate.
5. Refer to the user manual for detailed instructions on positioning, measurement timing, and interpreting results.

Maintenance

To protect your monitor from damage, please observe the following:

• Do not subject the monitor and the cuff to extreme temperatures, humidity, moisture or direct sunlight.
• Do not fold the cuff or tubing tightly.
• Do not inflate the arm cuff over 299 mmHg.
• Do not disassemble the monitor and components.
