24 Hour Blood Pressure Monitoring

Blood Pressure Monitoring (BPM) gives a recording of your blood pressure over a 24 hour period, while you move around, living your normal daily life. It uses a small digital blood pressure machine that is attached to a belt around your body and which is connected to a cuff around your upper arm. It is small enough that you can go about your normal daily life and even sleep with it on.

Why might I need a 24-hour monitor?

By measuring your blood pressure at regular intervals over 24 hours, your doctor is able to get clear pictures of how your blood pressure changes throughout the day and night, including the normal nocturnal dip. There are a number of reasons why your doctor might suggest this test:

  • To find out if your high blood pressure readings in the clinic are much higher than they are away from the clinic (called the 'white coat effect')
  • To see how well your medicines are working, to make sure they are controlling your blood pressure through the day.
  • To see if your blood pressure stays high at night. If this is the case, they may need to change or adjust your medicines.

What do I need to do during 24-hour blood pressure monitoring?

To allow the machine to work properly, it is important to make sure that the tube to the machine is not twisted or bent. Also, just before the machine is about to take a reading, it will beep. When this happens you should:

  • Sit down, if possible
  • Keep the cuff at the same level as your heart
  • Keep your arm steady

After the 24 hours have elapsed, the monitor is returned to the practice and the results are analysed and used to inform any treatment plan, if required.
