What is a 24 Hour Blood Pressure Monitor?

A 24 Hour Blood Pressure Monitor or Ambulatory Blood Pressure Monitor (APB) involves measuring blood pressure at regular intervals over a 24-hour period while you perform your normal daily activities.

The monitor will automatically pump up every half hour during the day (7am to 10pm) and every hour at night (10pm to 7am).

The monitor is portable and worn on a belt connected to a standard cuff on the upper arm and detects systolic, diastolic and mean blood pressure, as well as heart rate.

When complete, the device is connected to a computer to download information, which is then correlated by a cardiac technician.

How do I Prepare?

You will not be able to shower with a 24 Hour Blood Pressure Monitor on, as the device is unable to get wet, so you will need to coordinate bathing before or after wearing your device. A top with loose sleeves will best accommodate the cuff and a firm waistband will help support the monitor.

You should continue with your normal daily activities, including work and exercise. You should take all your usual medications.

When the cuff starts to inflate you should stop moving and talking, keep the arm still and relaxed, breath normally.

You will be given a sheet to keep a brief diary, which is important to record timing of activities, sleep, taking of medications and symptoms that may be related to blood pressure. If you feel any symptoms (dizziness, shortness of breath), you can record an additional measurement by pressing “start” on the device, and then record those symptoms in your diary.
