Researchers, comprising those from India, have designed an innovative smartphone application and hardware that can assist calculate blood pressure more precisely in comparison to the current cuff gadgets. The group in the U.S. from Michigan State University also invented a more suitable measurement point.
“We aimed a separate artery, the artery present at the fingertip and dubbed as transverse palmer arch artery, to offer us enhanced power to take the measurement,” claimed doctoral student at MSU, Anand Chandrasekhar, to the media in an interview.
“We were eager when we authenticated this spot. Being capable of using your fingertip makes our method more accessible and much easier,” claimed Chandrasekhar, who is senior author of the research posted in the Science Translational Medicine journal. The approach employs 2 sensors. An optical sensor is mounted on top of a force sensor. The other circuitry including the sensor unit are kept in a 1 Centimeter-thick box connected to the rear of the smartphone.
Consumers switch on the application and apply their fingertip touching the unit of sensor. With their finger touching the unit, they hold their handset at level of heart and watch their handset display to make sure they are putting the right amount of pressure by the finger.
“A major point was to look if consumers can correctly apply the pressure by finger over time,” claimed professor at MSU, Ramakrishna Mukkamala, to the media in an interview. “We were happy to see that 90% of the users attempting to use it were capable of doing it simply after only 1 or 2 practice attempts,” claimed Mukkamala.
While elevated blood pressure is curable with medication and lifestyle changes, only about 20% of users with hypertension have their situation in control. This invention offers patients a suitable alternative from the traditional options, claimed Mukkamala to the media.
