Omron HEM-6121 - Wrist Blood Pressure Monitor Manual

Introduction

The OMRON HEM-6121 is a compact and easy to use blood pressure monitor, operating on the oscillometric principle. It measures your blood pressure and pulse rate simply and quickly. For comfortable controlled inflation without the need of pressure pre-setting or re-inflation the device uses its advanced "IntelliSense" technology.

Intended Use

This product is designed to measure the blood pressure and pulse rate of people within the range of the designated wrist cuff, following the instructions in this instruction manual.
It is mainly designed for general household use. Please read the Important Safety Information in this instruction manual before using the unit.

Please read this instruction manual thoroughly before using the unit.
Please keep for future reference.
For specific information about your own blood pressure, CONSULT YOUR DOCTOR.

Important Safety Information

Consult your doctor prior to using in pregnancy or if diagnosed with arrhythmia or arteriosclerosis.
Please read this section carefully before using the unit.

Warnings

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

General Usage

• Always consult your doctor. Self-diagnosis of measurement results and self-treatment are dangerous.
• People with severe blood flow problems, or blood disorders, should consult a doctor before using the unit, as cuff inflation can cause internal bleeding.

Battery Usage

• If battery fluid should get in your eyes, immediately rinse with plenty of clean water. Consult a doctor immediately.

Preparation

Installing/Replacing the Batteries

1. Remove the battery cover.
   
2. Insert two 1.5V "AAA" alkaline (LR03) batteries as indicated in the battery compartment and then replace the battery cover.
   
   Notes:
   • If the battery low symbol () appears on the display, turn off the unit then replace both batteries at the same time.
   • The measurement values continue to be stored in memory even after the batteries are replaced.
     Disposal of used batteries should be carried out in accordance with the national regulations for the disposal of batteries.

Using the Unit

Applying the Wrist Cuff

Do not apply over clothing.

1. Place the wrist cuff over your wrist.
   Your palm should face upward.
   
2. Wrap the wrist cuff around your wrist.
   Wrap the wrist cuff securely around the wrist for taking accurate measurements.
   
   Make sure that the wrist cuff does not cover the protruding part of the wrist bone (ulna) on the outside of the wrist.
   
   Note: You can take a measurement on either your left or right wrist.
   

How to Sit Correctly

To take a measurement, you need to be relaxed and comfortably seated, under comfortable room temperature. No bathing, drinking alcohol or caffeine, smoking, exercising or eating 30 minutes before taking a measurement.

• Sit on a chair with your feet flat on the floor.
• Sit upright with your back straight.
• The cuff should be at the same level as your heart.
• Relax your wrist and hand. Do not bend your wrist back, clench your fist, or bend your wrist forward.
  

Taking a Reading

Notes:

• To cancel a measurement, press the START/STOP button at any time during measurement.
• Remain still while taking a measurement.

1. Press the START/STOP button.
   All the symbols appear on the display.
   The wrist cuff will start to inflate automatically.
   
   Cuff Wrapping Guide
   The Cuff wrapping Guide is a unique feature that indicates if the cuff is not wrapped tightly enough around the wrist.
   If the is displayed, it means the 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 wrist and the reading is accurate and reliable.
2. Undo the wrist cuff and remove the unit.
3. Press the START/STOP button to turn off the monitor.
   The monitor automatically stores the measurement in its memory.
   It will automatically turn off after two minutes.
   
   • 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.
   • Your blood pressure monitor includes an irregular heartbeat feature. Irregular heartbeats can influence the results of the measurement. The irregular heartbeat algorithm automatically determines if the measurement is usable or needs to be repeated. If the measurement results are affected by irregular heartbeats but the result is valid, the result is shown together with the irregular heartbeat symbol ().
     If the irregular heartbeats cause the measurement to be invalid, no result is shown. If the irregular heartbeat symbol () is shown after you have taken a measurement, repeat the measurement. If the irregular heartbeat symbol () is shown frequently, please make your doctor aware of it.
     Notes:
   • 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.
   • 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 the two arms differ substantially, please check with your doctor which arm to use for your measurement.

Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of your doctor.

Using the Memory Function

The unit automatically stores up to 30 sets of measurement values (blood pressure and pulse rate). If the memory is full, the monitor will delete the oldest readings.

To View the Readings Stored in Memory

1. Press the button.
   The Memory number appears for a second before the pulse rate is displayed. The newest set is numbered "1".
   
   Note: If there are no measurements results stored in the memory, the screen to the right is displayed.
   
2. Press the button repeatedly to view the readings stored in memory.

To Delete All the Values Stored in Memory

When the memory symbol () appears, first press the button. Then while holding it down, press the START/STOP button simultaneously for about 2 - 3 seconds.

Note: You cannot partially delete the stored readings.
