New Technology to Measure Blood Pressure Using Smartphone Videos

Take a video selfie and get your blood pressure measured. Yes, you heard it right, monitoring BP is now that handy.

Researchers have come up with innovative technology – ‘transdermal optical imaging’ which can monitor and measure your blood pressure with the help of smartphone captured video. The video detects changes in the blood flow which aids in measuring BP.

According to one of the researchers, the face video captured by the smartphone consists of some kind of information about the systolic blood pressure.

A Canada based professor from the University of Toronto stated that death rates and the number of disabilities have increased recently due to high blood pressure. Hence, regular monitoring of blood pressure has become more than a necessity, to prevent the condition.

Cuff-based devices to measure blood pressure are quite accurate but at the same time are uncomfortable and inconvenient.

Researchers have used all the necessary data and information to study the technology and understand how accurately facial flow patterns can contribute to monitoring blood pressure and pulse. And it was discovered that the transdermal optical imaging technology can monitor systolic blood pressure at an average accuracy of 95%.

The accuracy rate of this technology actually matches the international standards which are set for measuring blood pressure.

The researchers suggested that the facial videos captured for monitoring BP should be in an environment with good lighting, even home with controlled light is preferable. Only ensure the video is not unclear.

The study was conducted on varied skin tones, except extremely fair and dark skin.
