OMRON HEM-6161 Wrist Blood Pressure Monitor

Introduction

Thank you for purchasing the OMRON HEM-6161 Wrist Blood Pressure Monitor. This blood pressure monitor is to be worn on your wrist. This new blood pressure monitor uses the oscillometric method of blood pressure measurement. When the cuff inflates, this monitor senses the pressure pulsations of the artery underneath the cuff. The pulses are called oscillometric pulses. The electronic pressure sensor displays a digital reading of blood pressure.

2. Preparation

2.1 Installing Batteries

1. Push down the hook of the battery cover and pull downward.
2. Insert 2 "AAA" alkaline batteries as indicated in the battery compartment.
3. Close the battery cover.

Note: When the ? symbol flashes on the display, it is recommended you replace batteries. To replace batteries, turn your monitor off and remove all batteries. Then replace with 2 new alkaline batteries at the same time. Replacing batteries will not delete previous readings. The supplied batteries may have a shorter life than new batteries. Disposal of used batteries should be carried out in accordance with local regulations.

2.2 Blood Pressure Measurement Tips

To help ensure an accurate reading, follow these directions:

• Stress raises blood pressure. Avoid taking measurements during stressful times.
• Measurements should be taken in a quiet place.
• It is important to take measurements at same times each day. Taking measurements in the morning and in the evening is recommended.
• Remember to have a record of your blood pressure and pulse readings for your physician. A single measurement does not provide an accurate indication of your true blood pressure. You need to take and record several readings over a period of time.

Caution: Avoid bathing, drinking alcohol or caffeine, smoking, exercising and eating for at least 30 minutes before taking a measurement. Rest for at least 5 minutes before taking a measurement.

2.3 Applying the Wrist Cuff

Note: Following steps are for applying the wrist cuff to your left wrist. When you take a measurement on your right wrist, apply the wrist cuff using the same steps as on your left wrist. The blood pressure can differ between the right wrist and the left wrist, and the measured blood pressure values can be different. OMRON recommends to always use the same wrist for measurement. If the values between both wrists differ substantially, please check with your physician as to which wrist to use for your measurements.

Caution: Remove tight-fitting, thick clothing and any accessories from your wrist while taking a measurement.

1. Apply the wrist cuff to your left wrist. Roll up sleeve. Make sure your sleeve is not rolled up too tightly on your arm. This may constrict the flow of blood in your arm.
2. Put your wrist through the cuff loop. Your palm and monitor display should both face upward.
3. Position the wrist cuff leaving a clearance of 1 to 2 cm between the cuff and the bottom of your palm.
4. Wrap the wrist cuff firmly around your wrist. Do not apply over clothing. Check to make sure that there is no gap between your wrist and the cuff.

Note: Make sure the wrist cuff does not cover the protruding part of the wrist bone on the outside of your wrist.

2.4 Sitting Correctly

To take a measurement, you need to be relaxed and comfortably seated in a room with a comfortable temperature. Place your elbow on the table to support your arm.

• Sit in a chair with your legs uncrossed and your feet flat on the floor.
• Sit with your back and arm being supported.
• Your monitor must be approximately the same level as your heart. If the monitor is too high above your heart, your blood pressure will be artificially low. If the monitor is too low below your heart, your blood pressure will be artificially high.
• Relax your wrist and hand. Do not bend your wrist back, clench your fist, or bend your wrist forward.

3. Using Your Monitor

3.1 Taking a Measurement

Note: To stop the measurement, press the [START/STOP] button once to deflate the wrist cuff.

Caution: DO NOT use this monitor with other medical electrical (ME) equipment simultaneously. This may result in incorrect operation of the monitor and/or cause an inaccurate reading. Remain still and DO NOT talk while taking a measurement.

1. Press the [START/STOP] button. All symbols appear on the display before starting the measurement.
2. Remain still and do not move or talk until the entire measurement process is completed. As the cuff inflates, your monitor automatically determines your ideal inflation level. This monitor detects your blood pressure and pulse rate during inflation. The ❤️ symbol flashes at every heartbeat.

Note: The ✔️ symbol appears if the wrist cuff is wrapped around the wrist correctly. When the ❌ symbol is displayed, the wrist cuff is not applied correctly. Press the [START/STOP] button to turn your monitor off, then apply the cuff correctly.

After your monitor has detected your blood pressure and pulse rate, the cuff automatically deflates. Your blood pressure and pulse rate are displayed. If either the systolic or the diastolic reading is high (refer to section 1.3), the ❤️ symbol appears.

Measurement Status:

• [START button] -> [INFLATING] -> [COMPLETED]

3. Press the [START/STOP] button to turn your monitor off.

Note: Your monitor will automatically turn off after 2 minutes. Wait 2-3 minutes between measurements. The wait time allows the arteries to decompress and return to their pre-measurement form. You may need to increase the wait time depending on your individual physiological characteristics.

4. Using Memory Function

Your monitor automatically stores up to 30 readings.

4.1 Viewing the Readings Stored in Memory

1. Press the [Memory] button. The Memory number appears for one second before the pulse rate is displayed. The most recent reading set is numbered "1".

Note: If there are no readings stored in the memory, a specific screen is displayed. If the reading is high (refer to section 1.3), the ❤️ symbol appears. If the memory is full, the monitor will delete the oldest readings.

2. Press the [Memory] button repeatedly to scroll through the previous readings stored in the memory.

5. Other Settings

5.1 Deleting All Readings Stored in Memory

1. Press the [Memory] button, then the ? symbol appears.
2. While holding the [Memory] button down, press and hold the [START/STOP] button for more than 2 seconds.

Note: All readings will be deleted. You cannot partially delete the readings stored in the memory.
