A Guide to Monitoring Blood Pressure at Home

How to Measure Your Blood Pressure

The American Heart Association recommends six key steps to monitoring your blood pressure.

  1. Don’t smoke, exercise or drink caffeinated beverages or alcohol within 30 minutes of measurement.
  2. Rest in a chair for at least five minutes with your left arm resting comfortably on a flat surface at heart level. Sit calmly and don’t talk.
  3. Make sure you’re relaxed. Sit still in a chair with your feet flat on the floor with your back straight and supported.
  4. Use a properly calibrated and validated heart monitor that measures blood pressure on the upper arm. Check on the cuff size and fit.
  5. Place the bottom of the cuff above the bend of your elbow.
  6. Take at least two readings one minute apart — in the morning before taking medications and in the evening before dinner. Record all results immediately and share them with your doctor.
