Hello, wrist blood pressure monitorswrist blood pressure monitors haveactually grown in popularity in the last couple of yearsBut the question is this: do they actually do whatthey are designed for? That is to say:do they give you accurate bloodpressure readings?That's what this video is about.
I want to say a word or two aboutWrist blood pressure monitors versus upper arm monitorsThe key phrase there is: 'accurate blood pressure readings'Do these wrist blood pressure monitors actually give you accurate blood pressure readings?That's what this video is about, so stay tunedAnd I'll see you after the channel introWelcome back.
I'm Dr Joe of TheDrJoe.
comSo, wrist blood pressure monitors have grown in popularityEveryone seems to be buying them and using them to monitortheir blood pressure at home.
That's not a bad thing.
But I'm really concerned about what those wrist blood pressuremonitors are deliveringCompared to this stuff.
This is the upper arm monitor.
So, I'll start with the positivesWell, the wrist blood pressure monitors are easy to useSo long as you can actually wrapa wrist watch around your wrist, you canuse them.
They are just like a wrist watchWrap them round and off you go.
You get your blood pressure readingsSo, they are very easy to use.
There's no dexterity involved in actually using themThe 2nd thing is; they're very portableBecause they are smaller than this oneThan the upper arm monitors.
So, they are very easy to put or fit into your bag andOff you go, if you're travelling, you can take them along with youThat is not to say; these are bulky.
I meanthese ones are also easy to carry aroundBut in comparison to the upper arm monitorsThey are smaller.
So, I'll give that to themNow, Accuracy of blood pressure readings because that's the mostimportant factorin all of thisDo they give accurate blood pressure readings? I'll tell you a storyI first came acrosswrist blood pressure monitorsa couple of years ago.
About 4, 5, 6 years ago.
I saw a full-page ad in a newspapertalking about these wrist blood pressure monitorsI thought, that's a great idea.
And I thought, I will get one.
So, I got one for myselfIt arrived in the post a couple of days later andI was very keen to get on with itSo I applied it and I was getting some really wild blood pressure readingson the left arm.
Or left wrist, I should sayI did it twice.
I was getting ridiculous readings like240/160 mmHgI thought; that's not rightI transferred to the right wrist.
I was getting wild readingsOf course, because I have this one at homeI double-checked with that and I was getting low readingsAt the time my blood pressure was well-controlledI didn't believe the readings I was getting from itSo I called thethe retailerOkay, may be that's a dodgy one, sothey said I should send it backThey sent me another one.
So, I sent it back.
And I bought some more brands ever sinceat the timeI tried them and to be honestI got the same wild readingsSo, the point is: they don't give accurate readingsIn terms of accuracy, they fail on that oneIf you get decent readings, that's probably sporadicYou need something you can rely onSo, accuracy? There's a very big doubtabout wrist blood pressure monitorsas far as accuracy of blood pressure readings is concernedJust to underscore the point about accuracy, let me give a review.
What I'll callan honest review by a customer from that popular retailing websiteSo this customer wrote and I quoteHe says:I'm really disappointed with this productThe readings were wildly offcompared to my doctor's monitorand it was dubious to say the leastI want to return this product and get a full refundThat's what I call an honest reviewSo, why do the wrist monitors give unreliable readings?Well, for a start,the wrist blood pressure monitorsthey're ultra-sensitive to the body's positioncompared to the upper arm monitorsSo, that's the 1st reason.
The 2nd reason iswhen you're trying to measure your blood pressurethe cuffed part of the body, whether it is the wrist or the armit should be at the level of the heartand as you can tell, this is not a natural position for the wristIt's not a very natural position for the wrist to be inFor the arm, the arm isalready at the level of the heartSo, all it needs is a little bit of elevationand you are right thereSo, this is a natural position for the upper armThat's the 2nd pointThe 3rd point is that, the artery thatyou 're trying to measure the blood pressure offwith the wrist monitor is called the Radial ArteryThe radial artery is narrower andis a lot more superficial compared tothe Brachial Artery from which you're taking the blood pressure offwith theUpper arm monitorsthe brachial artery is bigger and more deeply setcompared to the radial arterythat is more superficial and narrowerSo, the blood pressure readings you get from the Radial artery areusually higher compared to the Brachial arteryit then begs the question; why do peoplego for the wrist blood pressure monitorsinstead of using the regularupper arm monitorsOne reason is this.
Some people havea big armIn which case, this regular size cuffwon't do.
It's going to give abnormally high readingsSo, they then gofor the wrist blood pressure monitor becauseit doesn't require a huge cuffWell, the way around that is; you go online andsearch for'big cuff for upper arm monitors'So, you just buy a bigger cuff.
So that takes care of that problemIndeed if you go online, you're going to see a lot of optionsfor you to buy the bigger cuffThe other issue is thatto use the upper arm monitor, it does require acertain amount of dexterityAnd some people have issues with that.
Here's what I'd say:What you need to do is; always threadthe free end of the cuffthrough the metal guideAlways thread it all the time.
Have it threaded throughAll you then need to do when you want to measure your blood pressureYou just slip your hand, your forearm throughAnd then slide it upAll you then need to do is FASTENHave it threaded through like this ready all the timeYou might think byvirtue of this presentation that I am Anti-InnovationWell, I am not.
Nothing could be further from the truthThe thing is; I'm all for InnovationBut if innovation does not come with reliability, then I'll be asking myself thequestion: what is the point?I've tested a lot of these wrist blood pressure monitorsand in my opinion, they fail the Reliability TestIt's for that reason, I will NOT recommend the wrist blood pressure monitorsfor you of you are watching this videoStick with this upper arm monitorsThey are reliable.
They give accurate readingsSo long as they are well calibratedAsk yourself this.
When was the last time you went into a hospital or a doctor's officeand you saw them using the wrist blood pressure monitors?After all,these wrist blood pressure monitors have been around for a good number of years nowWhy haven't they made their way intothe hospital environment.
It's for that same reasonThey are NOT reliableBecause they are very convenient to use and we should be using them in hospitalBut we don't.
It's because they are not reliableBy the way, I have donea video on the checklist, the guidelines onforgetting your blood pressure right every timeThe video should be up there now.
