  • What is the warranty on an OMRON home blood pressure monitor?

    The warranty period depends on which OMRON model you purchase or own. Warranty periods on the monitor itself (not including cuff) are generally anywhere from 1-5 years, and are based on the life expectancy of the unit. Most cuffs or other accessories are generally 1 year. Please check the instruction manual for your specific unit. Electronic versions of the instruction manuals can be found in the OMRON Product Support & Solutions Center.

  • What size cuff do I need?

    The correct size of cuff is based on the circumference of your upper arm, or your wrist, depending on which type of model you want. OMRON monitors cover a variety of sizes as mentioned below:

    D-Ring Upper Arm Cuff Sizing

    • Small adult cuff: fits upper arm with circumference between 7-9 inches
    • Standard adult cuff: fits upper arm with circumference between 9-13 inches
    • Large adult cuff: fits upper arm with circumference between 13 and 17 inches

    ComFit Cuff Sizing

    • ComFit cuff: fits upper arm with circumference between 9-17 inches

    Wrist Model Sizing

    • Wrist model: first wrists with circumference between 5¼-8½ inches.
  • Why is my wrist blood pressure monitor giving high readings?

    The most common cause of high readings when using a wrist blood pressure monitor is because the user does not have the wrist monitor at heart level. When using a wrist monitor, please ensure the device is at heart level when taking a reading. Also note that there may be actual differences between your blood pressure at the upper arm site and the wrist site.

  • Why should I monitor my blood pressure at home?

    The American Heart Association recommends that anyone with, or at risk of high blood pressure, should monitor their blood pressure at home. Home blood pressure monitoring is one of the best methods of trending a person's blood pressure in their own environment.

  • Will I see differences between my readings at home compared to readings in my doctor's office?

    Yes, you will see some differences. This is normal and can occur for many reasons. Some of the more common reasons are:

    1. A person's blood pressure varies throughout the day, so at any given moment your blood pressure can change.
    2. In terms of the amount of change; there are published studies that show a given person's blood pressure can change by up to 20 mm within a day, based on activity levels, food/drink intake, stress, etc.
    3. You may have a condition known as "White Coat Hypertension." This is a condition in which a blood person's blood pressure rises above its usual level when it is measured in a doctor's office or clinical setting.
    4. You may have a condition known as "Masked Hypertension." This is a situation in which a person's blood pressure falls below its usual level when it measure in a doctor's office or clinical setting.
    So do not be alarmed when you see differences between your readings at home compared to your readings in your doctor's office. Discuss it with your doctor to get the best overall picture of your heart health.
  • Can I use my Complete without pairing it to a smart device?

    Yes, you can measure your blood pressure without pairing your Complete to a smart device. However, to use the EKG measurement function, you must be paired to a smart device and connected to the OMRON Connect mobile app.

  • How do I properly take my blood pressure at home?

    To take your blood pressure at home, sit quietly for a few minutes, keep your feet flat on the floor, place the cuff on bare skin, and rest your arm at heart level. For users looking for a simple option, the OMRON 3 Series Upper Arm Blood Pressure Monitor is designed for easy at-home use with one-touch operation and app connectivity.

  • Are home blood pressure monitors accurate?

    Home blood pressure monitors can provide reliable readings when they are clinically validated and used correctly. Accuracy depends on proper cuff placement, the right cuff size, and measuring under consistent conditions. OMRON offers several clinically validated options, including the OMRON 7 Series, 10 Series, Platinum, and Evolv upper arm monitors.

  • What should I look for when buying a blood pressure monitor?

    When choosing a blood pressure monitor, look for clinical validation, a comfortable cuff, easy-to-read results, memory storage, and features that match your routine. For basic home monitoring, the OMRON 3 Series can be a practical starting point, while users looking for advanced features may consider the OMRON 10 Series or Platinum models.

  • Is a wrist or upper arm blood pressure monitor better?

    Upper arm monitors are commonly recommended for routine home monitoring because they are easier to position at heart level and closely match the method used in many clinical settings. However, wrist monitors can be useful for people who need a more compact option. OMRON offers both upper arm monitors, such as the 10 Series and Platinum, and wrist monitor options for users who prioritize portability.
