Indian-Origin Duo Develop App To Detect Sleep Apnoea At Home

"ApneaApp" correctly classified 32 out of 37 patients in the clinical study.
To determine, if a person is experiencing sleep apnoea events, "ApneaApp" transforms an Android smartphone phone into an active sonar system that tracks tiny changes in a person's breathing movements.
The phone's speaker sends out inaudible sound waves, which bounce off a sleeping person's body and are picked back up by the phone's microphone.
Because the sound waves are at a frequency adults cannot hear, the app easily screens out audible background noise from people talking, cars honking or a bedroom fan.
Right now phones have sensing capabilities that people do not fully appreciate.
"If you can recalibrate the sensors that most phones already have, you can use them to achieve really amazing things," added co-author Shyam Gollakota, assistant professor of computer science and engineering.
The initial results are impressive and suggest that 'ApneaApp' has the potential to be a simple, noninvasive way for the average person to identify sleep apnea events at home and hopefully seek treatment, the authors noted.
The app is much simpler to use than other home sleep apnoea tests.
"Using ApneaApp at home over the course of several nights or weeks could produce a more complete picture of real-life sleeping patterns," the authors concluded.
The researchers are now exploring the process of getting the US Food and Drug Administration (FDA) approval.
The clinical study will be presented at the "MobiSys 2015" conference in Florence, Italy, in May this year.
