Blood Pressure Monitor

An ambulatory blood pressure monitor is a small unit worn on your arm for 24 hours. This unit checks your blood pressure approximately every half hour. This test is ordered by a physician who is concerned about their patient’s blood pressure. A blood pressure monitor test will help the physician to make decisions on medications and other treatments. It may be used to evaluate how a medication is working. 

A physician may order a blood pressure monitor for the following reasons: 

  • White coat syndrome
  • High blood pressure
  • Low blood pressure

 This test is not covered by OHIP. The fee for a blood pressure monitor test is $80.00.

Frequently Asked Questions

How does the monitor work? A battery inflates the cuff and takes your blood pressure every half hour during the day and every hour during the night.
Do I have to do anything while wearing the monitor? Do not bathe or shower while wearing the monitor. Continue with regular activities throughout your day to get an accurate reading. When the cuff is inflating, keep your arm still.
Why did my physician order this test? Your physician wants to monitor your blood pressure during everyday activities.
Can I exercise? We encourage you to go about normal daily activities. If you do exercise, you will need to write this in the diary that we will give to you. If the monitor is taking a blood pressure during exercise, remain still for an accurate reading then resume exercise when its done checking your blood pressure.
Is the blood pressure monitor unit uncomfortable? The blood pressure can get tight while it is inflating. This is normal. Please remain still as moving will cause the unit to inflate tighter.
Can I still take my medications? Yes, you may continue to take your medications as normal as instructed by your physician.
I don’t think the monitor is working correctly. What do I do? Make sure the cuff is located about two inches above the elbow and is snug. Make sure the hose from the monitor to the cuff is not kinked. Keep still while the cuff is inflating.
What happens to the report/study when I return the monitor? We download the information to our computer system and forward a report to your doctor for interpretation.
