Research Summary:

COVID-19 has accelerated the need for remote respiration monitoring to support clinical management of patients in the home. In this study, we developed methods to accurately monitor respiration remotely using smartphone technology. These methods could facilitate low-cost and accurate respiration monitoring, suitable for monitoring large patient groups remotely.  Audio respiration data were collected remotely using smartphone microphones by 210 volunteers, including 53 volunteers with a previous diagnosis of COVID-19.  These data were used to develop a respiration monitoring method, and to automatically classify signal quality. Twenty-seven healthy volunteers also participated in a laboratory study to validate the audio methods against gold standard respiratory monitoring equipment.  The results of this study have been published (see publications). The researchers would like to thank everyone who volunteered for this study.
