Researchers Can Accurately Measure Blood Pressure Using Just A Cellphone Video Of Your Face

A new study published in the American Heart Association journal Circulation: Cardiovascular Imaging found that blood pressure can be measured accurately by taking a quick video selfie.

An anonymous reader quotes this announcement from the University of Toronto:

Kang Lee, a professor of applied psychology and human development at the Ontario Institute for Studies in Education and Canada Research Chair in developmental neuroscience, was the lead author of the study… Using a technology co-discovered by Lee and his postdoctoral researcher Paul Zheng called transdermal optical imaging, researchers measured the blood pressure of 1,328 Canadian and Chinese adults by capturing two-minute videos of their faces on an iPhone. Results were compared to standard devices used to measure blood pressure. The researchers found they were able to measure three types of blood pressure with 95 to 96 per cent accuracy.

Lee co-founded a company to turn their technology into a smartphone app (named Anura) that reports stress-level measurements and resting heart rate from a 30-second video of your face — with plans to release a new version also returning blood pressure results sometime this fall in China.

The university also notes that the researchers now hope to extend their technology so it can measure blood-gluclose levels and cholesterol.
