Now that would be a cool product. Lots of datapoints. 
I&#x27;m skeptical about the claim - yes, it&#x27;s important, but there are so many variables that feed into it, and I need to be convinced that constant, 24 hr monitoring of BP would enable better management than spot tests, home BP management and the occasional 24 hr ambulatory monitoring.<p>It&#x27;s a very consumer-targeted technology, although it would certainly find a place in emergency departments and ICUs.
I am at a loss to think of ways as to how we would actually capture the data, although better minds than mine I hope come up with ways.<p>The problem is that to get a good read on arterial pressure you either need to do it the old fashioned way (occlude the artery and record that pressure, then slowly drop it until it&#x27;s constantly flowing again - see [0]) - or you need to stick a cannula into an artery, as we do in ICUs, and measure pressure using a transducer.<p>Even technologies that stress their &#x27;passivity&#x27; (see [1]) and try to capture this market use the old fashioned way. I don&#x27;t see that changing anytime soon - you could try and somehow monitor the stretch of a small artery maybe using some variation of current o2 saturation sensors, coupled with advanced computer models of flow rate and variation in small arterioles, but that is a world away and would seem to me to be highly subject to variation&#x2F;sensitivity.<p>My prediction is that this won&#x27;t be possible until we are commonly implanting biometrics in people, but I guess we will wait and see!<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Korotkoff_sounds" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Korotkoff_sounds</a>
