Monitoring BP Through a Smartphone Application is Possible Now, Check it Out Here!

However, the app still needs to be validated in a standard regulatory test

Researchers have developed a novel blood pressure (BP) application that can give accurate readings using an iPhone, without requiring any special equipment.

Developed by the Michigan State University researchers, the new “iPhone X” app measures BP via the ‘oscillometric finger pressing method’, or ‘peek and pop’ that enables users looking to open functions and apps with a simple push of their finger.

The user presses her fingertip on both the front camera and screen to increase the external pressure of the underlying artery, while the application measures the resulting variable-amplitude blood volume oscillations via the camera and applied pressure via the strain gauge array under the screen.

The application, featured in the journal Scientific Reports, also visually guides the fingertip placement and actuation and then computes BP from the measurements just like many automatic cuff devices.

When tested, along with a finger cuff device, against a standard cuff device, the app yield indicated that cuff-less and calibration-free BP monitoring may be feasible with many existing and forthcoming smartphones, the researchers said.

“By leveraging optical and force sensors already in smartphones for taking ‘selfies’ and employing ‘peek and pop’, we’ve invented a practical tool to keep tabs on blood pressure,” said lead author Ramakrishna Mukkamala, Professor at MSU.

“Such ubiquitous blood pressure monitoring may improve hypertension awareness and control rates, and thereby help reduce the incidence of cardiovascular disease and mortality,” he added.

If things keep moving along at the current pace, an app could be available in late 2019, Mukkamala said.

However, the app still needs to be validated in a standard regulatory test.

“But because no additional hardware is needed, we believe that the app could reach the society faster,” he noted.

While high blood pressure is treatable with lifestyle changes and medication, only around 20 per cent of people with hypertension have their condition under control. This invention gives patients a convenient option and keeping a log of daily measurements would produce an accurate average. (IANS)

Apple has released the first public beta of its upcoming iPhone and iPad operating systems (OS), iOS 13 and iPadOS 13, open for everybody to download and experience the test versions.

The final version of the new iPhone and iPad operating systems is scheduled to release later this year, most likely by September, TechCruch reported on Monday.

However, because of bug-risks and chances of patchy experience, users are advised to proceed with caution and not install the beta versions on their primary iPhones and iPads.

According to the report, while some apps and features would not work at all as part of the beta tests, but in some rare cases, beta softwares could also brick devices and make them unusable.

Last week, the iPhone-maker announced the availability of the developer beta of iOS 13 and iPadOS 13.

Apple unveiled iOS 13 with features like the Dark Mode and Apple sign-in, a sturdy Mac Pro desktop for creative professionals and a 30 per cent snappier Face ID.

The new operating system on iPhones is loaded with India-specific features like the Indian-English accent for virtual assistant Siri that would now speak in a more natural and expressive way – in both male and female voices. The users would be able to access content drawn from Indian languages in a seamless conversational style.

According to the iPhone-maker, iOS 13 would reduce app download sizes by up to 50 per cent and make app updates over 60 per cent smaller, resulting in apps launching up to twice as fast.

With iPadOS, users would be able to work with apps in multiple windows, see more information on a redesigned Home screen and more natural ways to use Apple Pencil.

On the other hand, just like iOS 13, iPadOS with Dark Mode feature would be available this fall as a free software update for iPad Air 2 and later, all iPad Pro models, iPad 5th generation and iPad mini 4. (IANS)
