  • How do I assemble and apply the D-ring cuff?

    When the cuff is assembled correctly, the hook material will be on the outside of the cuff loop and the metal d-ring will not touch your skin. If the cuff is not assembled, pass the end of the cuff furthest from the tubing through the metal d-ring to form a loop. The smooth cloth should be on the inside of the cuff loop.

    1. Remove tight fitting clothing from your upper arm.
    2. Sit in a chair with your feet flat on the floor. Rest your left arm on a table so that the cuff is at the same level as your heart. Turn the palm of your hand upward.
    3. Put your left arm through the cuff loop. the bottom of the cuff should be approximately ½ inch above the elbow. The cuff tab should lie over the brachial artery on the inside of the arm. The cuff tube should run down the center of the arm even with the middle finger.
    4. Secure the cuff around your arm using the cloth closure. Pull the cuff so that the top and bottom edges are tightened evenly around your arm.
    5. Make sure the cuff is wrapped firmly in place. You should be able to fit your index finger between the cuff and your arm easily.
    6. Relax your arm and place your elbow on the table so that the cuff is at the same level as your heart.
    7. Be sure there are no kinks in the air tubing.
  • How do I know if I am using the correct cuff?

    To get accurate readings, and to avoid error messages, it is very important that you are using the correct size cuff and it is correctly applied to your arm. Please see your specific instruction manual.

  • How do I know if I have put on the arm cuff correctly?

    We recommend you apply the cuff using the following directions. First, make sure you have removed any tight-fitting clothing from your left arm. Put your left arm through the cuff loop. The bottom of the cuff should be about one-half inch above your elbow. Turn your arm so your palm is facing up. Adjust the cuff around your arm so that the tubing runs down the center of your arm. Secure the cuff so it stays in place.

    D-Ring Cuff

    You should be able to fit one finger between the cuff and your arm. This space is imperative for an accurate reading because OMRON's digital blood pressure monitors use the oscillometric method of blood pressure measurement that detects your blood's movement through your brachial artery and converts the movements into a digital reading.

    ComFit Cuff

    The cuff should be wrapped tightly around the arm. If the cuff slips or easily turns, the cuff should be tightened. If the cuff is wrapped too loose or too tight, you may get an inaccurate reading of error message. For more detailed directions, please refer to the instruction manual for the specific model.View a short video on how to apply the OMRON ComFit cuff.
  • How do I measure my arm circumference?

    To determine your arm size, use a cloth tape measure and place midway between your elbow and your shoulder around the circumference of your upper arm. Wrap the tape measure evenly around your arm. Do not pull the tape tight. Note the precise measurement in inches. Determine which size cuff is best for you, then purchase a home blood pressure monitor with that size cuff included. View a short video on selecting the right D-ring cuff.

  • Is it necessary to have the batteries installed in the monitor when using the AC adapter?

    No, the monitor will work on AC power without having the batteries installed in the device.

  • Is it normal for my blood pressure to vary?

    Yes, it is quite normal for people's blood pressure to change throughout the day and night, or in different settings where you may measure your blood pressure. Many things, such as stress levels, food or drink intake, activity levels, even time of day can all affect a person's blood pressure reading at any given time. In fact, there are published studies that show a given person's blood pressure can change by up to 20mm within a day, based on activity levels, food/drink intake, stress, etc. This is why it is important to take your blood pressure on a regular basis, and review the overall trend of your blood pressure readings with your doctor.

  • My blood pressure is not responding to the medications my doctor prescribe. What should I do?

    You should contact your doctor and discuss the situation. Only your doctor is qualified to diagnose and prescribe medication, or make changes to medications in managing blood pressure.
