Topic Overview

An ambulatory blood pressure monitor is a small device that is worn throughout the day, usually for 24 or 48 hours. The device takes your blood pressure automatically while you do your normal activities.

The device periodically inflates and takes blood pressure measurements, which are recorded for later printout and analysis. The devices are usually loaned by a clinic, hospital, or pharmacy.

You doctor might ask you to use one of these monitors if you might have white-coat (or office) hypertension or there is a difference between the blood pressure you have at home and in your doctor's office. These monitors are also valuable for diagnosing and treating high blood pressure in pregnant women and older adults.

If you are required to use an ambulatory blood pressure monitor, keep in mind that it is important for a health professional to properly size the cuff, which fits around your arm. Fitting does not take long.
