It is really very convenient. It does not inflate, but if it is not in the right position on the wrist it does not get a measurement. I think it is tracking skin movements or movements in capillaries. If the results were more in line with Omron I would think is very good.

I have now worn it for about 6 weeks. Because it is not invasive I am more inclined to keep wearing it and see if I get any useful information from it. I do quite frequent checks with Omron which is a standard upper arm cuff. My doctors tend to use Omron devices and I have I think 5 in different locations.

It weighs 20 grams and it is not possible to detect when it measures blood pressure which is does every 2 hours, around 10 measurements a day. I think it only measures BP if you are very still, and it does multiple measurements around the same time it seems and then averages it out. It’s pretty insane value to me to get BP reading in such an easy way which is a very important marker for current and future health. Tech seems sci-fi.

You get averages for every two hours, but number of measurements is far greater, up to about 1000 in a day, that number will depend of how still you are. it only measures when you are still and not moving

I think you are mistaken, it says it is taken several times an hour randomly if the user is determined to be sitll using an accelerometer:

Might be. I haven’t checked their site in a while, but did in depth research in March and my memory is just so good. But I from what I remember it said that it will try to measure BP every few minutes… maybe they have changed something?

@RapAdmin @AnUser

Not sure if you saw this. Seems to be FDA approved (which for devices tends to be more difficult than CE mark it seems).

Pro is that it uses inflation and hence is probably more accurate

Con is that it uses inflation and hence you’ll probably notice it

Above wrist version is by this brand that @John_Hemming used for his stationary BP device

The Aktiia blood pressure bracelet also seems to have FDA approval.

Aktiia FDA Approval - Statcare.

Interesting. They don’t seem to have updated their own webpage and doesn’t seem available to buy in the US yet?

Aktiia is only available in countries where we have received regulatory clearance. Currently, those countries include the United Kingdom, France, Germany, Austria, Switzerland, the Republic of Ireland, and Italy.

Where is the Aktiia app available? : Aktiia.

Maybe I’m wrong, I just did a search and posted the first entry. It’s 4:40am where I am so I’m going back to bed. I’ll do a more thorough search when I get up. Apologies if I’m wrong

My apologies. The Aktiia blood pressure bracelet is NOT FDA APPROVED.

I think the people who published the press release in January 2023 got confused by this article.

….and by this quote from above article

"Aktiia is available in the USA for inclusion in clinical investigations, under an Investigational Device Exception. Pending FDA authorization for commercial availability.”

I’m not going to use a device with inflation personally, as that is not going to work as it will probably wake me up during sleep or be annoying generally. The Aktiia is very accurate, similar to a 24h ambulatory one.

There is always going to be rare exceptions that have inaccurate results. Using a wrist one with inflation feels like going back to the stone age compared to this. I think this will also get more accurate over time. I don’t even like using regular inflation ones as its a bit of a hassle. The aktiia comes with one that is used every 30 days for calibration though.

#143

Funny you should say that :laughing:. I bought mine off Gumtree from a guy in Northern Ireland, who bought it to use for a 24h ambulatory blood pressure measurement as part of a hospital visit.

I may still try the inflating wrist system. I am going to stick with Aktiia for now. I don’t think it is that accurate (when compared to measurements by Omron cuffs, but there may be usable information from it.)

The average data of the Aktiia from 7 days is said to be equivalent to 1 day of AMBP:

Doing 1 or 2 readings with Omron in a 2 hour window vs. multiple readings that are most likely done at different times randomly is comparing apples to oranges I think.

#146

It depends on how stable the cardiovascular system is. If you get up and do some exercise then the heart rate and blood pressure will vary, but if you settle down and basically don’t move materially or do any exercise (and are some distance from eating) then it will stabilise (putting and psychological stresses aside). Hence the value you get from Omrom at such a point should be comparable to a value from Aktiia.

#147

If the Aktiia did the measurement at around the same time as the Omron, then I of course believe the Omron to be more accurate. However the value Aktiia provides is the measurements when you don’t use the Omron, during night, and the average over days, weeks, months, and trends.

#148

For those that like Omron and believe that pressure based tech is the gold standard, then here is the cheaper albeit bulkier solution that seems design for during the night also by Omron than the watch by Omron above. Have not looked into it, but thought I’d share.

Omron NightView Silent Automatic Wrist Blood Pressure Monitor HEM-9601T-E3

Clinically validated wrist monitor to use for automated overnight readings - with data transfer to the Omron app

The Omron NightView is a completely silent way to measure daytime blood pressure and automatically measure nighttime blood pressure, while still sleeping soundly.

It is clinically validated so you can rely on the readings obtained. NightView is the first at-home wrist monitor designed to measure nighttime blood pressure.

Even with controlled daytime blood pressure, 1 in 4 people still have a condition called nocturnal hypertension.

Interesting… definitely something people might want to consider. But I wonder if its still going to wake you up during the night. While the sound is one factor… the sudden constriction around your arm has to be something I would think could impact your sleep…

The device has completely silent pumping action for minimal sleep disturbance and measures with gentle inflation and less compression time

Yeah, wonder where this one is in the spectrum - smaller, but a bit more expensive
