The best blood pressure monitor won’t break the bank

Blood pressure

We tested blood pressure monitors and found six Best Buys, but almost as many Don’t Buys. Surprisingly – it’s not always about the price. Our tests showed that expensive monitors aren’t necessarily the best.

If you have high blood pressure and the very thought of going to the GP’s surgery sends it through the roof, you are probably relying on your home monitor to keep you firmly in control of those all-important numbers.

Using a blood pressure monitor at home can be very useful, and for April’s issue of Which? magazine we tested well-known brands including Omron, Boots and IBP to find out how accurate and helpful they are.

So why have we found, not for the first time, that so many monitors don’t make the grade when we put them through their paces against three international standards, in clinic conditions?

In our blood pressure monitor tests, the wrist monitors have fallen down again – although we did find reliable examples – and this is likely to be for a practical reason. You have to lift the wrist to heart level if you’re using a wrist-worn monitor, and this introduces inconsistencies into readings.

Expensive doesn’t mean excellent

Often when I’m buying goods on the high street, I’ll use price as an indicator of quality, but this rule isn’t as easy to apply for blood pressure monitors. Although pricier models tend to have fancier features, some of our most accurate monitors were the cheapest. Sometimes, basic can be just as good as high spec.

As many as 16 million people in the UK suffer from high blood pressure, some of whom don’t know they have it if they have no symptoms. It’s vital that those who turn to home monitoring get a correct result.

The British Hypertension Society has lists of validated monitors, but we also rate usability and tell you models that are Don’t Buys as well as the Best Buys.

Do you monitor your own blood pressure? How did you choose your monitor and are you confident that it gives you accurate readings?

I bought a Boots BP monitor with an arm cuff and used it for a few years now. Recommended by my Doctor who used a similar monitor. The readings seem consistent and in line with the occasional surgery reading. My Doc is happy to check them side by side when I visit (rarely) – must remember to take it next time. I found it useful to take regular readings over a week or two before a BP check, helping avoid the white coat syndrome which seems to result in inflated readings, as I’m not a great fan of pills.

I am type 2 diabetic and have regular BP checks (4 times a year), as part of my treatment. As I suffer from ‘white collar’ higher BP results when I visit the surgery I have used a Boots BP monitor since May 2003 (model code 22-42-532). It has given very consistent results and has been tested against the equipment used at the surgery. It is also still operating on the original batteries..

I used to have a Boots wrist blood pressure monitor which was little more than a random number generator, even taking care to keep my wrist at the correct height as Joanna mentions in her introduction. I know others who have had the same problem with wrist-type monitors.

I now have an Omron blood BP with a cuff. I have not compared it with my GP’s meter but the readings seem plausible and that is reassuring.

I purchased an Omron M7 shortly after discovering I had high blood pressure. At that time most doctors at my surgery seemed to prefer manual blood pressure gauges but I have noticed that, over the last three to four years the Omron M7 has taken over. I had not thought to take my own gauge in to check it against theirs but will do so in the future. I have been pleased with the Omron though a little concerned and curious at the huge price difference between it and other manufacturers.

The only Which test I can find on BP monitors is 2.5 years ago !
I assume you are talking about a more recent review can you post a link to it please ?

Joanna has said that they were tested for the April issue of Which? magazine, so maybe we will find something on the website soon.

Thanks, I always thought that Which had a strict embargo on articles before the Magazine was actually posted to subscribers but they seem to have done away with it recently !

They’ll be online soon Rarrar. Sometimes things go online a little earlier because members start getting mags from the weekend. In those mags are links to these Conversations (which makes us happy!), but those links need to be live. If they’re not, when members type them in, they get broken pages! And that makes people unhappy! So, that’s why it might look like things are going online ‘early’, when really we’re just trying to keep everyone happy 🙂 Reviews take a little longer to get online, but you won’t have to wait much longer

Two of the makes of BP monitors have a model in the Which? ‘Best Buy’ category and another model in the ‘Don’t Buy’ category, because of poor accuracy.

On the basis that most of the models tested were inaccurate, perhaps there is a case for requiring BP monitors to meet the requirements of the British Hypertension Society before they can be sold in the UK.

Congratulations Which? on a really useful article.
