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)

To Avoid China Ban, Apple Will Update iPhones

The ban does not cover the new iPhone XS, iPhone XS Plus or iPhone XR, which were not yet available when Qualcomm filed its lawsuit.

Apple has decided to update iPhones in China to avoid a ban after a court ruling banned the sale and import of most iPhone models after granting Qualcomm an injunction against Apple.

According to a report in The New York Times on Friday, the Cupertino-based tech giant said it would update the software of iPhones in China early next week to try to resolve the legal dispute.

The company said it would update its iPhones “to address any possible concern about our compliance with the order”.

“Apple said its update would change the iPhones’ software so it did not infringe on Qualcomm patents, which relate to switching between apps and changing the size and appearance of photographs,” said the report.

Apple and Qualcomm are suing one another in courts across the world. Billions of dollars are at stake, and each side has claimed some victories.

A Chinese court had banned the sale and import of most iPhone models after granting Qualcomm an injunction against Apple, a stunning decision that comes amid the trade war between the US and China.

Apple, however, is still selling iPhones in China.

According to Don Rosenberg, Qualcomm’s Executive Vice President and General Counsel, Apple is violating the court’s order.

“They are legally obligated to immediately cease sales, offers for sale and importation of the devices identified in the orders and to prove compliance in court,” he was quoted as saying.

Apple has also appealed against the Chinese court ruling.

It accused Qualcomm of playing dirty tricks, including asserting a patent that had already been invalidated by international courts, and other patents that it had never before used.

“Qualcomm’s effort to ban our products is another desperate move by a company whose illegal practices are under investigation by regulators around the world,” Apple said in a statement earlier this week.
