    Best blood pressure monitoring watch

    Hi all,

    Do any of you use a watch with blood pressure monitoring, my blood pressure is all over the place and I don't always have time to use a cuff monitor, it needs to be accurate as I have to submit readings to a doctor, any info would be greatly received

    I don't think you can monitor the Bear Pit from your watch...

    I have a watch that measures your blood pressure, the Casio BP-100.

    You do need to set the watch up first by inputting your BP measurement from an accurate device. After that, the watch can measure changes in BP and produce an actual figure.

    I have one of these, but the sensor does not respond to me at all (It's the same with touch screens at the supermarket self-checkout). Even so, I don't think they're accurate enough for your purposes. You need to use the cuff and proper machine. As a doctor, I would not accept a patient's readings done on a device of this sort - the quality of information given by this wouldn't allow me to tailor your treatment. My view is that it's a fun gimmick, no more.

    +1, exactly my thoughts when I saw this. People are becoming conditioned to believe numbers generated by devices such as watches, phones etc without questioning whether they're likely to be reliable. Anything health-related needs to give an accurate picture.

    Just use the proper cuff. Smart watches are hopelessly unreliable on just about everything.

    I use an Omron unit daily, and I just timed myself using it.

    40 seconds end to end.

    Includes rolling up my sleeve, fastening the cuff, pressing the button, the machine doing it's thing, writing down the reading, taking off the cuff, and rolling down my sleeve again.

    40 seconds.

    if you can't find 40 seconds at each end of the day for something to do with your health that you profess to be concerned about, then I don't know what to say !

    Rather inconvenient if you’d like to monitor your bp while on a walk, climbing steps or another activity.

    The actual Doctor who has commented in the thread has already advised that the OP needs to use a proper cuff, and the proper cuff comes with a set of instructions on how to perform the measurement, which doesn't involve climbing stairs or being out on a walk.

    Yes, appreciate how a suitable measurement should be taken for medical purposes.
    On top of this some people may still like see how their bp varies whilst climbing stairs or being out on a walk.

    “ What is the significance of blood pressure monitoring?

    Blood pressure refers to the pressure of blood on the blood vessel wall when the heart beats, usually expressed as systolic blood pressure (SBP) and diastolic blood pressure (DBP).

    Healthy blood pressure is the key to maintaining the normal function of the cardiovascular system and preventing cardiovascular disease.

    FitHop Fitness Trakcer uses smart chips and optical technology to accurately monitor blood pressure fluctuations, check blood pressure status anytime and anywhere, and effectively help discover and warn of hypertension, cardiovascular and other diseases.”

    I was giving blood a year ago and the nurse advised me my BP was on the high side and I should consult a doctor. I purchased the bracelet awaiting the doctors appointment and the readings were similar to what the reading at the blood bank was.

    The bracelet at least here in Switzerland is medically approved and at least my doctor was familiar with the product and the app can give you a daily, weekly or montly chart of the low/high and the average for each day. You have to do one cuff measurement a month to keep the bracelet calibrated. The positive is, if you have a white coat syndrome this bracelet takes a "non-invasive" measurement each 30 minutes so it will give a more precise picture than the ocassional standard measurement.

    I could see how my BP was going up or down with sport activies and food or sleep.

    Anyway as I was borderline high BP my doctor didn't recommend therapy but to keep an eye for the moment so I tried introducing a lot of different things to see if any changes in the food and drink will make a difference, finally I found the absolute best thing for me is 1.5h running or power walking in the morning and the average falls into the green for the whole day.

    Well the inflating cuff is the usual medical measurement standard and I don't think Casio claim that the watch readings can be used instead of these. I wrote this when reviewing the watch.

    "The watch actually uses a combination of two sensor technologies.

    The pad on the left reads the pulse using a photosensor, exactly like the Lungman.

    The pad on the right is one lead of a two-lead ECG probe that's built into the watch, the other lead is on the watch backplate. Those leads measure the electrical signal that accompanies your heart beat. For the system to work properly, the watch's backplate must make contact with your bare wrist. In addition, your right hand can only touch the two sensors when measuring because otherwise you would create an alternate conduction path.

    But how does Casio use these sensors to measure blood pressure? It relies on a concept called "Pulse Wave Transit Time," or PWTT.


    PWTT, by itself, can only tell you the relative changes in blood pressure, not an absolute number. Therefore, you have to input some basic data into the watch before using any of its blood pressure features. After you input your normal resting blood pressure, you're good to go. You can also input your post-exercise BP to use the more advanced functions.


    I checked my BP with my machine and entered the data into the watch and then checked my BP with the watch and it was very close to the machine measured data. The watch also retains data from each measurement in its memory and these can be recalled showing the time and date of the measurement. You can have a graph of your changing BP displayed in timekeeping mode if you wish."

    There have been a number of studies about PWTT.

    100% agree on this. Blood pressure measurement is serious. Your bp goes up and down even standing and sitting. Swanbourne wrote on a bp thread here one “ in the army they make you sit in a darkened room for ten mins before taking a reading”

    Having a dynamic reading is like an “ instantaneous fuel consumption “ view on your car. One minute 150/90 mm the next 120/75. 150 is medication time, 120 is pat you on your back and send you on your way.

    Doctors ( mine have) ask for two readings a day for 7-14 days , then they average am/ pm over the period. The exact opposite of measuring it on the move.

    I recently had to collect some medication from Tesco's pharmacy. After queuing for about 10 minutes I finally made it to the counter, whereupon I was told it wasn't ready so I should walk around the store and come back in 30 minutes. 20 minutes later I rejoined the queue for another 10 minutes and was finally presented with my medication. The assistant then tried to talk me into having a blood pressure test, with a smile on my face I told her that after having to queue for 20 minutes and walk around tesco's for another 20 there wasn't a hope in hell of me passing a BP test, the dispensing chemist was at the back of the dispensary sniggering his head off - but the assistant completely failed to see the humour and scowled at me

    As others have said, I can't see how these so called 'Blood Pressure monitoring' devices could work.

    Any time I've ever had my Blood Pressure taken it's been with a cuff - You can buy fairly accurate ones online for not much money.

    I can see the appeal of such a device, on the other hand. My elderly mother gets dizzy sometimes and has had some falls and the doctor's think it's a BP issue, but obviously it's hard to prove that the falls she's suffered WERE due to a BP drop.

    Something you could wear all the time that kept a history, would be excellent, but I don't see anything that can do that with any degree of accuracy so far.

    And whoever invents something that can monitor ambulatory BP to clinical standards will make an absolute fortune.

    I have just had to wear a holter for 24 hours to check my low heartbeat.

    Very compact nowadays pretty much the size of a credit card although you have to have the stickers on your chest.

    Yes.
    Sorry, I should have added some sort of device without a cuff.

    Check out this video. The channel is excellent as it takes a genuine evidence based approach to measuring the performance of a wide range of wearables.

    I wouldn't trust a watch to monitor my blood pressure or to do an ECG... and I worked as a medic.

    I am currently monitoring my blood pressure.
    I had a bought blood pressure machine which tended to mark me as 'fine' compared to the GP's cuff. I bought another to make sure.. and that was similar.
    Then one day the new one carried on inflating and didn't stop.

    I then went out and purchased a 'better machine' that was officially recognised and sanctioned by the UK and Ireland hypertension organisation, BIHS.

    And guess what? My blood pressure is reading HIGHER than the two others I bought. This new one is definitley more in line with my GP readings and even though technically I am more 'unwell' LMAO... I want this stuff to be right. It was £28 on Amazon too.

    So... two ACTUAL blood pressure machines... with good Trustpilot ratings etc... not good enough IMHO. And that is solely their manufactured purpose.

    On that thinking... would I trust a watch to read my blood pressure accurately?

    Not on your nelly.


    *I know how to measure one manually with a steth too.. and what actually happens to the CV system in the process.

    They hurt your arm for a reason hahaha.
