How to Measure Blood Pressure at Home

A repeatable setup helps make home readings more useful to you and your health professional. Use a properly fitted cuff, take the reading while seated and relaxed, then record more than one result.

Home monitoring can give your clinician readings taken outside the exam room. It does not replace medical visits or diagnose a condition by itself. If a clinician has asked you to monitor, follow their schedule and bring the monitor and your log to an appointment.

Choose a monitor that fits

The American Heart Association recommends an automatic, cuff-style monitor that measures at the upper arm. Choose a model validated for accuracy and a cuff sized for your arm; the AHA links to ValidateBP to look up validated devices. If you have questions about a wrist monitor, a special cuff size or a device for pregnancy or a child, ask a health professional which type is appropriate.

Take the monitor to a medical appointment so a professional can check that you are positioning it correctly and compare its readings with office equipment. Follow the monitor’s instructions for cuff placement and maintenance.

Prepare for a clean reading

• For 30 minutes beforehand, avoid smoking, caffeine and exercise.
• Empty your bladder.
• Put the cuff on bare skin, not over a shirt sleeve.
• Sit quietly for at least five minutes. Avoid conversation, phone use and other distractions.

Food, drink, recent activity and posture can affect a measurement. The CDC’s measurement guide recommends a quiet rest and a consistent position each time.

Set your body and cuff in position

1. Sit upright in a chair with your back supported.
2. Keep both feet flat on the floor and your legs uncrossed.
3. Rest your forearm on a table so the middle of the cuff is at heart level; keep your palm facing up and your arm relaxed.
4. Place the cuff on your bare upper arm, with its lower edge just above the bend of the elbow. Check the monitor’s manual for the exact fit.
5. Stay still and do not talk while the device takes the measurement.

Take two readings and write them down

Take at least two readings, one minute apart. Measure at the same time each day if your clinician recommends regular monitoring, and follow their instructions about how often to check. Record the date, time and both results. Bring the log—or the device’s stored readings—to your next appointment.

What to do with a high reading

A single high reading is not enough to diagnose high blood pressure. Repeat it after a short rest and record both results; contact your health professional for guidance about what the numbers mean for you. Do not start, stop or change medication based only on home readings unless your clinician tells you to.

The AHA says that if a reading is above 180/120 mm Hg, wait at least one minute and measure again. If it remains that high, contact a health professional immediately. If a reading that high occurs with symptoms such as chest pain, shortness of breath, weakness, numbness, vision changes or difficulty speaking, call 911.
