How are 24-hour ambulatory blood pressure readings taken?
BP readings are taken continually over a 24-hour period. You’ll wear a device that is about the same size as a portable radio. The device is attached to a belt or strap worn on your body. It collects information throughout the 24-hour period that will later be transferred to a computer.
You’ll wear a BP cuff that is attached to the device around your upper arm. (The cuff can be worn under clothing so it isn’t visible.) The cuff inflates at certain intervals throughout the day and night. You may be told to keep a diary to record your daily readings. This can help show how changes in your BP relate to periods of activity or rest.
After 24 hours, you can remove the device and BP cuff and return the equipment to your clinic or doctor’s office. A computer analyzes the readings and generates results.
