Although for measuring blood pressure not only modern electronic ones are used, but also old ones, blood pressure monitors tested over the years, science does not stand still and in this plan.
So, scientists at the University of Toronto Paul Zheng and Kang Lee developed a completely new technology for determining blood pressure with using TOV (transdermal optical imaging). For this not you do not even need any ultra-modern tonometer, enough with using a smartphone or computer, take a selfie and send it, for example, your healthcare provider. And he is not only easy and fast determine your condition, but also immediately give the necessary recommendations.
In principle, in the near future, all this can be done by yourself at home, as computer and mobile applications that can determine your selfie blood pressure.
The whole secret of this technique is that our skin is translucent, and modern optics are able to capture the shade, which creates hemoglobin located in the subcutaneous capillaries. Thanks to this, TOV captures the strength and changes in blood flow, and then – produces the result. Its accuracy is 95 percent, moreover this is commensurate with the professional use of the tonometer, for example, by the attending physician. Patients themselves, using the device, sometimes make serious mistakes and get results far less accurate, what technology TOV can do.
As scientists at the University of Toronto said, using their technology in the near future it will be possible to determine not only blood pressure, but also the level of hemoglobin or glucose in the blood, the same cholesterol and some other indicators of human health. And for all you need is just to take a selfie using modern smartphone …
