Blood pressure monitor


There is no special preparation for the test, however there are some things you may want to consider.

  1. You will not be able to shower or bathe while wearing the monitor so you may want to do this prior to your appointment

  2. For your comfort, you may wish to wear a loose-fitting short sleeve shirt to ensure that the cuff fits underneath your clothing

  3. You will need to list your medications on a take-home worksheet, if you bring them in with you the technologist may be able to assist with this!

  4. This test is NOT covered by OHIP and you will be required to pay $75 at the time of your appointment. We accept cash, credit, debit, and cheque for transactions.


This test is performed in Medical Centre 1

Suite 206, 430 The Boardwalk, Waterloo, ON

Please head to the CPS Registration Desk and we will direct you from there.

A blood pressure cuff will be placed around your upper arm by one of our highly trained cardiovascular technologists (CVTs). This is attached to a device that inflates the cuff and records your blood pressure. This is a painless test; however some people find the pressure of the cuff uncomfortable while it is inflating.

How long will my appointment be?

15 mins


The monitor will inflate to take your blood pressure every 30 minutes during the day, and every 60 minutes throughout the night. All pressures are recorded within the device and will be downloaded and interpreted by a qualified member of the CPS team upon return. A report will be written by one of our CVTs and will then be sent back to your doctor.

There are some things to remember while wearing the device:

  1. The monitor cannot get wet. Do not bathe, shower, or swim while wearing the monitor.

  2. This device is sensitive and must not be tampered with. 

  3. While wearing the device, please avoid the following

    • Electric blankets​

    • High-voltage areas

    • Magnets

    • Metal detectors


Note: You may be asked to remove the device if you are going for other testing such as an MRI, CT scan, or X-ray​


We have two secure grey CPS return boxes (see right) you can use to return your monitor. The first is located on the main floor across from the elevators, and the other is found outside our doors of Unit 206. 

Both boxes act similar to mailboxes. Please refer to the figure below to see steps of the return process.

More Information

Your blood pressure is a measurement of the force of blood felt by the walls of your arteries (the blood vessels that primarily move blood away from the heart and towards the rest of your body).


Your blood pressure consists of two different numbers. The top number is called your systolic, and it measures the pressure in the arteries while the heart is contracting. The bottom number is called your diastolic, and it measures the pressure in the arteries while the heart is relaxing.
