Ann: Positive Results from At-Home Sleep Apnoea Study, page-79

Regarding the next phase of product developments you mentioned.
My thoughts are that we will see the rap wearable rugged devices now in development deliver constant monitoring of COPD and Asthma by the wearer. Not just 5 particular coughs but every cough and wheeze 24 hours. A fairly simple extension of the AI already in place.
I also note Professor Abeyratne’s research and interest in other body sounds particularly IBS- Irritable bowel syndrome.
A paper he has authored on the subject.
