    1

    Prepare before taking your reading

    ~21s
    Sit quietly for five minutes before measuring. Do not drink coffee, exercise, or smoke for at least 30 minutes before. Sit in a chair with your feet flat on the floor — do not cross your legs. Rest your arm on a flat surface at heart height.

    Quick Tip

    Try to take readings at the same time each day so you can spot trends over time.

    2

    Put on the cuff correctly

    ~27s
    Slide the cuff onto your upper arm — the bottom edge should sit about one inch above the inside of your elbow. It should feel snug but not painfully tight. You should be able to slip two fingers under it. Push up your sleeve so the cuff is on bare skin, not over clothing.

    Warning

    Using the wrong arm size cuff gives inaccurate results. Check the measurement guide on the cuff packaging to confirm you are using the right size for your arm circumference.

    3

    Take the reading

    ~15s
    Press the Start button. The cuff will inflate and then slowly deflate. Stay still and quiet — do not talk or move your arm during the measurement. The device will display your systolic, diastolic, and pulse numbers within about 30 seconds.
    4

    Record and track your results

    ~20s
    Write the reading in a notebook or log it in the device's companion app (for example, Omron Connect or Withings Health Mate). Record the date, time, and which arm you used. Many apps will draw a chart over time so you can see trends.

    Quick Tip

    Take two readings one minute apart and average them. Most monitors do this automatically.

    5

    Share results with your doctor

    ~17s
    Before your next appointment, print or screenshot your log. Many apps let you export a PDF or share directly with a provider through Apple Health or Google Fit. Ask your doctor what range is healthy for you specifically — targets can differ based on age and other health conditions.

    A digital blood pressure monitor (also called a home blood pressure cuff) lets you check your blood pressure any time without going to a clinic. These devices are widely recommended by doctors — home readings are often more accurate than office readings because you are relaxed in a familiar place.

    Blood pressure is recorded as two numbers, for example 120/80. The top number (systolic) is the pressure when your heart beats. The bottom number (diastolic) is the pressure between beats. Most health organizations consider a normal reading to be below 120/80. Your doctor may have a specific target range for you.

    Modern monitors connect to your smartphone via Bluetooth and record every reading automatically. Popular brands include Omron, Withings, and QardioArm. Most are available at pharmacies or online for $30–$80.

    Consistent technique matters more than the device brand. Always take your reading the same way each time: same arm, same sitting position, same time of day. If you take it right after exercise or a stressful conversation, the reading will be higher than your true baseline.

    Doctors often recommend the "morning and evening" rule — take one reading in the morning before you take any medications and one reading in the evening before bed. Write down or save both, and bring the log to your next appointment.

    Quick Tip: Most home monitors have been validated by medical organizations. Look for one that says it is "clinically validated" on the box.
