Description

The Omron HEM-7113 features a sleek and ergonomic design that makes it comfortable to use. The large LCD display ensures that readings are clear and easy to read, even for those with vision impairments. The device comes with a latex-free cuff that is adjustable to fit various arm sizes, ensuring a comfortable and accurate fit.

The monitor includes a hypertension indicator that alerts users if their blood pressure readings fall into the hypertensive range. This feature is particularly useful for individuals who are monitoring their blood pressure as part of a health management plan.

Preparation

Installing/Replacing the Batteries

1. Turn the main unit upside down.

2. Slide the battery cover in the direction of the arrow while pressing the ribbed part of the cover.

   

3. Install or replace four “AAA” size batteries so that the + (positive) and - (negative) polarities match the polarities indicated on the battery compartment.

4. Put the battery cover back in place. 
   Slide the battery cover as indicated, until it clicks into place.

   

   Note: The measurement values continue to be stored in memory even after the batteries are replaced.

Battery Life & Replacement

If the battery low symbol () appears on the display, replace all four batteries at the same time.

1. When the battery low symbol () starts to blink, you will still be able to use the unit for a short while. You should replace the batteries with new ones ahead of time.
2. When the symbol () remains lit, the batteries are exhausted. You should replace the batteries with new ones at once. Turn the unit off before replacing the batteries.

• Remove the batteries if the unit will not be used for three months or more.
• Dispose of batteries according to applicable local regulations.

Four new “AAA” alkaline batteries will last for approximately 300 measurements, when used to take two measurements a day. Since the supplied batteries are for monitoring use only, they may have a shorter life and not last for 300 measurements.

Using the Unit

Applying the Arm Cuff

Be sure to wrap the arm cuff correctly so that you get accurate results. Measurements can be taken in light clothing. However, please remove thick clothes, such as sweaters, before taking a reading.

Note: 
You can take a measurement on either your left or right arm. 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 physician which arm to use for your measurement.

1. Insert the air plug into the air jack on the left side of the main unit.

2. Apply the arm cuff to your upper arm. The air tube should be centred on the inside of your arm and point down the inside of the arm, so that the air tube runs down the inside of your forearm and is in line with your middle finger.

   

3. When the cuff is positioned correctly, close the fabric fastener firmly.

   

Taking a Reading on the Right Arm

Apply the cuff so that the air tube is at the side of your elbow.

Notes:

• Be careful not to rest your arm on the air tube, or otherwise restrict the flow of air to the cuff.
• The cuff should be 1 to 2 cm above the elbow.

Taking a Reading

1. Sit on a chair with your feet flat on the floor and place your arm on a table so that the arm cuff will be at the same level as your heart.
   Keep still and do not talk during measurement.
2. Press the START/STOP button to turn on the unit.
   Note: To cancel a measurement, press the START/STOP button to turn off the unit and to release the air in the arm cuff.

3. Check the measurement results.
   The unit automatically stores blood pressure and pulse rate into its memory. Refer to “3.4 Using the Memory Function”.

   

   Notes:

   • Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of your doctor.
   • Wait 2-3 minutes before taking another blood pressure reading. Waiting between readings allows the arteries to return to the condition prior to taking the blood pressure measurement.

4. Remove the arm cuff.

   

   Important: Your blood pressure monitor includes an irregular heartbeat feature. Irregular heart- beats 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 measure-ment, repeat the measurement. If the Irregular heartbeat symbol () is shown frequently, please make your doctor  aware of it.
   What is Irregular Heartbeat?
   An irregular heartbeat is a heartbeat rhythm that varies by more than 25% from the average heartbeat rhythm detected while the unit is measuring the systolic and diastolic blood pressure. If such an irregular rhythm is detected more than twice during measurement, the irregular heartbeat symbol () appears on the symbol when the measurement results are displayed.

   

   
   What is Arrhythmia?
   A heartbeat is stimulated by electrical signals that cause the heart to contract. Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-electrical system that drives the heartbeat. Typical symptoms are skipped heartbeats, premature contraction, an abnormally rapid (tachycardia) or slow (bradycardia) pulse. This can be caused by heart disease, aging, physical predisposition, stress, lack of sleep, fatigue etc. Arrhythmia can only be diagnosed by a doctor through a special examination. Whether the appearance of the irregular heartbeat symbol () in the results indicates arrhythmia or not can only be determined by an examination and diagnosis by your doctor.
   Warning: If the irregular heartbeat symbol () is shown frequently, please make your doctor aware of it. Conducting self-diagnosis and treatment based on measurement results is dangerous. Be sure to follow the instructions of your doctor.

5. Press the START/STOP button to turn the unit off.
   Note: If you forget to turn the unit off, it will automatically shut itself off after five minutes.

Instructions for Special Conditions

If your systolic pressure is known to be more than 220 mmHg, press and hold the START/STOP button until the arm cuff inflates 30 to 40 mmHg higher than your suspected systolic pressure.

1. Press the START/STOP button to turn the unit on. Measurement starts.

   

2. When the cuff starts to inflate, press the START/STOP button and keep it pressed until the pressure is 30 to 40 mmHg higher than your suspected systolic pressure.
   Note: You cannot inflate the cuff above 299 mmHg. (An error will be displayed  if you try to inflate the cuff above 299 mmHg.)
3. Release the START/STOP button when the cuff has been inflated to the desired pressure.
   The cuff starts to deflate and measurement starts.
4. The rest of the procedure is the same as for normal measurement. Refer to “3.2 Taking a Reading”, steps 3 to 5. Note: Do not apply more pressure than necessary.

Using the Memory Function

This unit has a memory capable of storing 14 sets of readings.

Note: If the memory is full, the monitor will delete the oldest readings.

1. Press the Memory (M) button.
   The result from the most recent measurement is displayed.
   Important: If your systolic or diastolic pressure is outside the standard range, the heartbeat symbol will blink when the measurement result is displayed. 
   Refer to “3.2 Taking a Reading”.
   Note: If there are no measurements results stored in memory, the screen to the right is displayed.

2. Press the Memory (M) button repeatedly to cycle through the previous measurement results.
   The Memory number appears for a second before the pulse rate is displayed. 
   The newest set is numbered “1”.
