Monitoring your blood pressure at home is an important part of staying on top of your health. Whether you’ve been advised by a medical professional to track your readings or you simply want to keep an eye on your numbers, a reliable blood pressure monitor can make a real difference.
This guide will help you understand what to look for in a monitor and how to choose the right one for your needs.
What should you consider when choosing a monitor?
Whichever home blood pressure monitor you go for, you must ensure it is labelled as being ‘clinically validated’ by the British Hypertension Society. This is a guarantee that the equipment has been thoroughly tested and that you can rely on the accuracy of its readings.
Prices vary, and you will pay more for equipment with more features, such as built-in memory. However helpful these additional features may seem, remember they are not necessary. You just need a good machine that you can afford, and pen and paper to take your readings.
Do Blood Pressure Monitors Need Maintenance?
Yes. Like any medical device, your monitor should be maintained to keep it working accurately. It’s best to send it to the manufacturer every two years to have it recalibrated.
Does cuff size matter?
Machines measuring blood pressure in the upper arm come with a cuff you wrap around your arm, and the wrong-sized cuff will produce an incorrect reading.
Place the cuff halfway between your shoulder and elbow.
Before buying, measure your upper arm. If its circumference is 18-22cm, you need a small cuff; for 22-32cm use a medium sized one. Bigger arms require a large cuff.
Bear in mind that most monitors are supplied with a medium cuff, and you may have to buy a different size separately.
Types of Blood Pressure Monitors
There are three main types:
- These Automatic digital blood pressure monitors are inflated at the push of a button and display results on a screen. They’re the most popular for home use because they’re straightforward to read.
- Manual blood pressure machine require a stethoscope and are mostly used by trained professionals. They are accurate but less convenient for everyday users.
- This Wrist blood pressure device is lightweight and portable, but correct positioning is essential. They are best for occasional readings when you're on the go.
When to Replace Your Blood Pressure Monitor
Like other devices, your monitor should be replaced when it stops delivering reliable results. If your readings become inconsistent or vary greatly from what your doctor’s equipment shows, it may be time for a new one.
Also, consider replacing your monitor every 3 to 5 years, especially if the cuff or electronics show signs of wear. Even high-quality models lose accuracy over time. Many people don’t realise how important regular calibration is-some brands allow recalibration, but in other cases, replacing the device is more practical.
